16/32-bit Microprocessor

The D68000-CPU32 soft core is binary-compatible with the industry standard 68000’s CPU32 version of the 32-bit microcontroller.

Overview

The D68000-CPU32 soft core is binary-compatible with the industry standard 68000’s CPU32 version of the 32-bit microcontroller. The D68000-CPU32 has a 16-bit data bus and 24-bit address data bus. It is code compatible with the MC68008, MC68010 and CPU32 (version of MC68020). The D68000-CPU32 has an improved instructions set, which allows program execution with higher performance than the standard 68000 core. It contains a built-in DoCD-BDM debugger interface. The D68000-CPU32 is delivered with fully automated test bench and complete set of tests, allowing easy package validation at each stage of SoC design flow.
