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.

D32PRO, scalable & royalty free 32-bit CPU

D32PRO is one of the newest 32-bit CPUs available on the market. It’s been designed by Digital Core Design, IP Core provider and SoC design house from Poland, responsible e.g. for the world’s fastest or world’s smallest 8051 CPU. DCD launched more than 70 different architectures since 1999, which have been implemented in more than 300 000 000 electronic devices, that’s why one can be sure that quite considerable experience stands behind the D32PRO.
