16/32-bit Microprocessor with BDM

Overview

The D68000-BDM soft core is binary-compatible with the industry standard 68000 32-bit microcoprocessor. It has a 16-bit data bus and a 24-bit address data bus. Of course, its code is compatible with the MC68008, upward code compatible with the MC68010 virtual extensions and the MC68020 32-bit implementation of the architecture. Our efficient IP Core has an improved instructions set, which allows to execute the program with higher performance, than a standard 68000 core.
The D68000-BDM s delivered with fully automated test bench and complete set of tests, which allow easy package validation at each stage of SoC design flow.

A special testing platform has been built to run D68000-BDM with uCLinux Operating System.
