M68000-compatible, High-performance, 32-bit Microprocessors , Inc

The MC68040 MC68040V MC68LC040 MC68EC040 and MC68EC040V (collectively called M68040 are Motorolas third generation of M68000-compatible, high-performance, 32-bit Microprocessors All five devices are virtual memory Microprocessors employing multiple concurrent execution units and a highly integrated architecture that provides very high performance in a monolithic HCMOS device. They integrate an MC68030-compatible integer unit (IU) and two independent caches. The MC68040 MC68040V and MC68LC040 contain dual, independent, demand-paged memory management units (MMUs) for instruction and data stream accesses and independent, 4-Kbyte instruction and data caches. The MC68040 contains an MC68881/MC68882-compatible floating- point unit (FPU). The use of multiple independent execution pipelines, multiple internal buses, and a full internal Harvard architecture, including separate physical caches for both instruction and data accesses, achieves a high degree of instruction execution parallelism on all three processors. The on-chip bus snoop Logic which directly supports cache coherency in multimaster applications, enhances cache functionality. By Freescale Semiconductor, Inc
