7.2 MC68040
This section presents an overview of the Motorola 68040 32-bit microprocessor. Emphasis is given to the coverage of its on-chip floating-point hardware.
7.2.1 Introduction
The MC68040 is Motorola’s enhanced 68030, 32-bit microprocessor. The MC68040 is implemented in Motorola’s latest HCMOS technology. Providing an ideal balance between speed, power, and physical device size, the MC68040 integrates an MC68030-compatible integer unit, an MC6888l/MC68882-compatible floating-point unit (FPU), dual independent demand-paged memory management units (MMUs) for instruction and data stream accesses, and independent 4K-byte instruction and data cache. A high degree of instruction execution parallelism is achieved through the use of multiple ...
