DESCRIPTION

The WC32P040 is a 68000-compatible, high-performance,

32-bit microprocessor. The WC32P040 is a virtual

memory microprocessor employing multiple concurrent

execution units and a highly intergrated architecture that

provides very high performance in a monolithic HCMOS

device. It has a 68030-compatible integer unit (IU) and

two independent caches. The WC32P040 contains dual,

independent, demand-paged memory management units

(MMUs) for instruction and data stream accesses and

independent, 4-Kbyte instruction and data caches. The

WC32P040 has a 68881/68882-compatible ﬂoating-point

unit (FPU).

Independent Instruction and Data MMUs

Simultaneously Accessible, 4-Kbyte Physical

Instruction Cache and 4-Kbyte Physical Data Cache
