High Perfomance Multitask Processor For Real Time Applications

A new high performance 16 bit NMOS microprocessor is presented which is dedicated to time critical multitask applications. A hardware implemented task scheduler allows the handling of up to 8 concurrent tasks with a medium restart latency time of 5.25 ¿s. The memory address space is 1 Moyte and the I/O space 128 bytes. High regularity in chip layout is achieved using bitslice technique in the data path and PLAs in the control section.
