Abstract

A system and method of detecting events such as DMA requests, computation operations, configuration set-up operations, occurring in a processing system which are performed by functional system blocks within the system by using logic flags stored in registers within each of the functional system blocks. The registers are coupled to the CPU on dedicated signal lines. Each time a functional block completes an operation or function it updates its corresponding logic flag. The CPU monitors the state of the flags to determine whether certain events have taken place in the system in order to sequentially coordinate functions and operations within the system without the use of interrupt signals on the system bus.
