<p>PURPOSE: To speed up a processing by receiving first data, interrupting the processing of a first process, accessing to a second register set and processing a second process. CONSTITUTION: At the time of the operation of a system, the selectors of respective CPU pick out the processes which can be executed among register sets R, R2.... A processor P executes an instruction for the selected process until access to one (for example) of memory banks M1, M2... is required. Then, the processor P typically sends a pertinent memory request for reading or writing a memory, and imposes conditions on one o flags F1, F2... so that the execution of the process is reported to be impossible. Then, the selector S selects the process which is flagged as that which can be executed, and which can be used next. Thus, the high speed processing can be executed.</p> |
