SuperH (SH) support

The SuperH (SH) architecture is a 32-bit RISC ISA originally developed by Hitachi as the successor of the H8 Family for use in embedded systems and was later outsourced to a SuperH Inc., owned by Hitachi and ST Microelectronics. Nowadays the CPU family is supported and designed by Renesas.

Known for its compact, efficient instruction set and good code density, SuperH processors were often used for graphic intensive embedded systems, powering devices like automotive controllers and the Sega Dreamcast.

J-Core: Open-Source SuperH

J-Core is a fully open-source implementation of the SH-2 ISA, designed for FPGAs and ASICs. It adds modern features like MMU and SMP, runs Linux, and is ideal for custom embedded applications. As a libre CPU core, J-Core continues the SuperH legacy with a focus on transparency and flexibility.
