Description

Sunplus S+core is Taiwan first self-defined 32-bit RISC CPU with Sunplus-owned instruction set architecture (ISA). The ISA has 32/16-bit hybrid instruction mode. The optional MMU is said to support Linux OS. To obtain the support for Linux OS, you may need to email [email protected] directly as no drivers are available on the website.

According to Sunplus website, the main application for Sunplus S+core is used on SPG290A, an SoC designed specifically for TV game and handheld game products. SPG290A is composed of S+core, a 32-bit CPU developed by SUNPLUS Technology, Picture Processing Unit (PPU), Sound Processing Unit (SPU) and other primary functions for video game and ELA applications.

SPG290A is able to generate graphics and sound for the television system (NTSC or PAL) and LCD.
