Abstract

A method and apparatus for implementing device simulation. A slave device without Universal Serial Bus (USB) client controller is inserted into a master device, and enumerated as a USB device. Control messages from the master device are parsed; the slave device implements transmitting data with the master device through General Purpose Input/Output (GPIO) interfaces, controls end point buffer to save the data transmitted between the master device and the slave device according to the parsed control messages. According to the method, in the situation that a device does not have a hardware USB client controller, by simulating USB data transmission through the GPIO interfaces of device chip, the master device can identify the inserted slave device as a USB device, the data transmission functions between the master device and the slave device are implemented, and it makes that the transmission based on USB can be used more widely.

Description

 Various methods and devices

 This relates to the field of communications, and in particular to various methods and apparatus. Background

 Looking at the informatization, the more embedded, the more popular. In the following, different information communication functions will be informatized. Currently, ve sa SeTa B s (SB) has many types of communication methods, namely, s sa, high speed, and the like.

 However, considering the cost, many of the current functions of the hardware SB client controller are not available, even if the SB slot is inserted, why not have the SB of the SB client controller, and the SB has not yet Propose an effective solution. Content

 In view of this, the purpose of this is to provide various methods and devices for each SB that does not have a hardware SB client controller.

 Solve the wood, the wood plan is

 Each device does not have a universal (SB) client controller, each of which is plugged in,

 1 is the device of this

 2 is the difference of each device of this

Schematic

 4 is the device of this in SB

Message flow and receipt 6 is the flow of each method of the present. Hugh way

 In the phase, there will be no SB client controllers.

 SB each, this considers that SB communication requires the use of 吋 difference, the medium of force, and S. The characteristics of 1 SB have different requirements. Therefore, this proposal is different from the general (Ge ea se p /O, GPO), and the GP connection force can be used as the front force, so that it can be used for household and power systems. Each SB, SB

 , to help the various communication methods.

 Here's the rest of this.

 In this case, various devices are provided, and the devices can be used in each. Each of them needs to be each of the SBs.

 As shown in Fig. 1, each device of the present system includes the SBB S e ce aye 1. The GPO is connected to each of the connected ones, including receiving the SBs that are not autonomous.

 And each of the SBs (SB evCe aye) 2, each of the control registers (, B), the memory is used to be sent by the master to each under the control of each 2, and each will be sent to Each of the two main supports the batch (B) and control (Co o ) modes, where Co o is for each SB and B is for each file function (SBF co aye ) 3 , for each SB Each, and parsing the commands that are not autonomous, and

. In the case where each of the upper devices does not have a hardware SB client controller, each GPO is connected to the SB, so that each of the masters (i.e., each of the plugs, each of which may include, etc.) inserts each of the SBs. In addition, considering the rate of each, nearly 5 low SB each, in S. 1 Each has its own.

 Among them, the GPO can be connected to each other, wherein the GPO connected letters form a difference, and the respective contents are different from the upper device of the difference, and the functions using the GPO are not received. In the case of the GPO function, the level of the GPO function is not 0 or 1, and the contents of each of the GPO functions are available for the GPO function.

 Since the GPO is connected up or down, and the SB has the same requirements on the rising edge, the falling edge, and the stability of the flat letter, the GPO is required to be connected. Taking into account the various, the device provided can be low SB each, for example, can be S. 10 of 1.5 / s.

SB 1.1 requires SB to meet the requirement of 2, that is, up to 4.6V, the lowest 1. V, the highest value is the same as the minimum 6 s, the rising edge and the falling edge are the same 42 s, the period is 166.7 s, The frequency of 6 z GPO is connected to the highest 3.3V, and the 5 SB of each of the 5 meets the requirements shown in 2, in each SB 1 can be connected with the same GPO with the middle and the function, or the difference or the GPO is not connected, so that the requirements shown in 2 can be met, and the 2 GPO can be used as the force difference P and For the SB of the sum P, for example, the SB will each have a low SB. 3, each ( aseba ) P, and VS, that is, the PCOTG (CO TheGo) connection shown in 3, increase the stabilizer (ow opO eg ao, O) force, can be improved , and can be added

The GPO connection, that is, the GP CT and GP CT 2 shown in 3 are not controlled by O, and the O management (Powe a age e , ) is connected, and, in the middle, the middle and the middle are received. each. Hugh, pick up

 1 Control information that can be received or in each.

 And, as shown in 1 , 1 is sent to each SB in the near/receive, and the solution and the remainder are

 (Cyc cRed da cyChec, CRC), the obtained (P) is returned to each message (AC) or message (A), and each SB is obtained, and in addition, there is a near error.

Each 2 can be used for each of the registers, and the like. Hugh, each 2 can be SB each (Res eRese S spe d), 矣 type of middle (each, OT) (E North e, medium E dpo, group ( ac e ) (Fa eCo C e E dpo E dpo FFO , And (Se dsa Se sa F s FFO p Tdy odeFFOF FFO OTE PT ), can be connected to the 1 interaction request (ep Req es, RQ) global, / receive whether there is spare storage, whether there are friends in the memory. Moreover, in the present device, the register can be EP and P parts, wherein the EP can be used for each of the SB audios, and so on. Among them, the EP component EP and EP T parts, the EP is stored in the received control information, EP T

 The storage of the control information EP also divides the E and EP T parts, the storage of the received files, the storage of the files of the EP T, and the storage and storage of the SB (SBB s aye ). Includes rest information for control information and files.

 Function 3 Near SB program connection (pp ca o oga g e ce, 1) and SB each 1, function 3 can be 2 C d, 1 interaction, to each, each SB, some control.

 4 is the message flow of the SB of the device.

 Among them, the program can be configured in the sheep (e p SeTVce Ro e, SR), in each.

 4, SR, that is, in the SB, the receiving SB will be SB to / receiving, and can be high SR(S) in the event, each can be viewed,

 / receiving SB, SB internal

In the memory, the corresponding function message, function

Receive in the register, will exist in the existence of reason Each message will be received/received in the SR, and will pass the message function, by function.

 In addition to the hardware, the framework proposed by SB can be said that each program is not connected.

The function. For each and function, you can separate functions.

 5 The process of receiving and receiving this device.

 5, first of all, it is necessary to establish three receiving and 13, GPO connected to the low, and the sca e file can be connected to each internal RA.

 The low SBs are each controlling the largest Payoad 8B e, and the most BP +daa+CR 8+64+bs F+ +B s , where B s is filled, whether it is wrong or not, so it is receiving /, ie (12+1) bye The control information of the reception or the storage is not stored, and the received or unstored file is not stored.

 In each program, SB, ie GPO, AR (Adva cedRSC ach es) command RQ fast (as e T p Req es, FQ), in rabbit. GPO connection

 , .

Synchronization (SY) x 0001, if it is Rese, then it is passed by SR, and each received Rese is SB, then CRC, non-inverted (oRe T ze o ve s , Rz ), remove B s , SB The analysis, including 矣, , content. If it is Se p or O e L, it means that the power is the main control information, which must follow, in the ATA / ATA, whether there is spare memory before storage, if not, then return to the handshake A, if there is, then This is the same as by SR. If it is not ATA / ATA, you can make the AR, and the GPO is connected.

 If the SB parsing is e L, it means that the memory is empty, if there is, then adding B s , R , Rz to send out the fruit does not mean that each SB client does not have each good, return Handshake A

 If each is good, can, if there is any before, if it does not exist, then the handshake A exists, then, Rz, add synchronization.

 In the return A or , you can make the AR, and the GPO is connected.

 On, the device needs to meet the following requirements.

 Each of the same requirements in the same requirements is in each of the requirements of ACe, as required by Rese, S spe d.

 The strength of the low SB is 1.5 / s each , required . 5 with b, if the C is waiting, because waiting is the same

 The occupied instruction period is multiplied by the P/frequency, so the method b/1.5 considers the requirement that the AR 4 statement does not receive and the instruction (oOpe aos, O) instruction does not match, and here, all In this, not external, unsigned

. In the above reason, in the middle of the same need to meet the following requirements all the reception, R, B s, address (that is, the address of each destination address received), and the handshake, and the need to be in the same, in the GP connection is the same High requirements, the front is the same, because the same loss 2, 3b, can be synchronized, fake lost 5, 6b, and lost, often, directly in the ARM4 program added procedures SB, Receive, etc. Therefore, the reverse of RQ is very common. Usually F is the same as 1.1 to 1.2 s, and the speed of low SB is the second place of SY C, so you can go to SY C.

 In the line of P, P Seep is prohibited in the same period, and (C) function can also be disabled, and P can work at a specific frequency.

 For each, in OR, the same value of the comparison, usually 45 times the command line speed, if it is in the internal S, can not refer to the speed of the instruction, so

Internal medium. Need to pay attention to this, otherwise it is easy to exceed the internal size.

 In the rationale shown in Figure 5,

 First, the EP, EP EP (B eT) 12 is established to store the received or control information EP (B e □ 16 , for storing the received or file.

Upon receiving the message of the medium SR, the system C functions to receive the SB step, and if it is Rese, then each, each B and the receiving phase are, will receive The B-step parsing, extracted to dev x 6], B each received the result is &, received 0, error, does not receive the function of the message, each, then in step, including adding ATA / ATA P information

5 system function.

 For function, it needs e 矣, 假, SB, function needs to fill the memory, message, that is, control information is fake in the file, then the file system, stored in the Fash or file to the memory, the message 0 .

 In the case of storing the RA4 file, you can use o Fash or a dFash with lower speed. Also note that

 To each, because of the low maximum Payoad 8, so it needs to be multiple times, and packaged, you need a large number of A first, each still 5 is working, but there is not much time, and a lot of processor resources are consumed. Similarly, in receiving each, frequently switching to medium mode reception also consumes a large amount of processor resources.

 This device is the largest Payoad 8 B e in B O y Ta s, so the second occupied B

 SY C+P + ATA+CRC 6+ P+ 8+8+64+B s F+ 6+2+ 99+ B s , so the maximum can be reached on the device

 1.5 *64/9g+B s f )/8*70% efficiency loss 850 Bye/S 83 ye/s

 , in terms of efficiency loss including operating system, other SB as higher priority as occupied resources.

5 This method is provided in close proximity to each other, 6

Various methods include Step 601: Each of the SBs does not have the hardware SB client controller, and each SB is analyzed, and the control information is not analyzed.

 Step 603, each GP is connected to the same number, and the analyzed control information is controlled by the same number of registers.

 .

 The number of GP connections is different from that of the GPO, and the respective numbers are represented by 吋 difference.

 Moreover, in the case of each direction, the difference between the various directions of the city is included, so that the predetermined requirements are met, and the predetermined requirements refer to the requirements of the SB, and the rest is not.

 Up, with the help of the top wood, in the case that each hardware SB client controller is not provided, the number of SBs connected to each GPO is such that each SB of each main plug is inserted. In addition, considering the respective rates, each of the low SBs will be each near S. 1 each with the same number.

 The above is better than the limit, and any modifications, equivalents, etc. made in this spirit and principle are included in this document.
