Microprocessor

Description

The TS68040 is Atmel’s third generation of 68000-compatible, high-performance, 32-

bit microprocessors. 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 manage-

ment units (MMUs), including 4K bytes independent instruction and data caches. A

high degree of instruction execution parallelism is achieved through the use of multi-

ple 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 appli-

cations with dedicated on-chip bus snooping logic.

TS68040

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-gener-

ated 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 pipe-

lined 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 log-

ical-to-physical address translations by storing recently used translations. The bus

snooper circuit ensures cache coherency in multimaster and multiprocessing

applications.
