The TS68040 is a virtual memory microprocessor employing multiple, concurrent execution units and a highly integrated architecture to provide very high performance in a monolithic HCMOS device. On a single chip, the TS68040 integrates a 68030-compatible integer unit, an IEEE 754-compatible floating-point unit FPU , and fully independent instruction and data demand-paged memory management units MMUs , including 4K bytes independent instruction and data caches. A high degree of instruction execution parallelism is achieved through 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. The TS68040 also directly supports cache coherency in multimaster applications with dedicated on-chip bus snooping logic. The TS68040 is user-object-code compatible with previous members of the TS68000 Family and is specifically optimized to reduce the execution time of compiler-generated code. The 68040 HCMOS technology, provides an ideal balance between speed, power, and physical device size. Figure 1 is a simplified block diagram of the TS68040. Instruction execution is pipelined in both the integer unit and FPU. Independent data and instruction MMUs control the main caches and the address translation caches ATCs . The ATCs speed up logical-to-physical address translations by storing recently used translations. The bus snooper circuit ensures cache coherency in multimaster and multiprocessing applications.
