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