Abstract

Data processing apparatus has a central processing unit which is arranged to form a plurality of processors, and is connected to a memory. In use, the central processing unit swaps one process for another, and for each swap writes into the memory an identification of at least one of two respective processes at a time related to the time occurrence of the respective swap. The memory is monitored by monitoring means which stores each identification with a timestamp indicative of the time at which the identification was written into the memory, and hence of an associated time of occurrence of the swap. The monitoring means thus can determine which processes are being performed during which periods of time, whilst having a minimal effect on the operation and design requirements of the central processing unit. One example of the monitoring means determines a proportion of time spent on each of the processes under consideration during each of a plurality of windows of time. The results of this analysis can be shown in graphical form with the windows of time plotted on one axis and the proportions on the other axis.
