ABSTRACT:
A system for managing the flow of real time data streams into a data system cache memory is disclosed. The data system includes a central processing unit or micro controller, with a cache memory, which operates at a relatively fast operating speed, near that of the central processing unit. An interrupt controller is provided as well as a quantization timer that disables the interrupts to the CPU during an execution quantization (EQ) period, and allows the interrupts to pass at an EQ boundary. In operation, the quantization timer controls interrupts to occur only when cache load actions are at a specific quantized time, thus ensuring that a given task in the cache will execute or load for a given quantized length of time, and therefore, the possibility of loading a cache randomly only to execute a few instructions is eliminated.
