THIS PAPER will discuss a 32b microprocessor implemented on a 290mil square chip containing approximately 60K transistors. The processor* is the first of a family of 16/32b microprocessor components. The device supports software transparent extensions of the basic instruction set through the use of slave processor chips. One such slave processor, a memory management unit, added to the processor will implement a demand paged virtual memory system. The basic instruction set contains 82 instructions supporting operations on 8, 16 and 32b integers, strings, packed decimal, bit/bitfields, arrays and high level program control constructs.
