S+core is a hybrid 32/16-bit instruction set architecture designed by Sunplus Technology.
The 32-bit microarchitecture features Advanced Microcontroller Bus Architecture (AMBA) support and includes SJTAG for In-circuit emulation. It is implemented on the Sunplus SPG290 system-on-a-chip (SoC).
Before the SPG (S+core) the company designed the 8bit SPLB31A/GPLB31A and PLB20D2 based on the MOS Technology 8502 and 6502 microprocessors respectively. The Sunplus/ Generalplus SPLB31A/GPLB31A is an embedded chip that integrates LC display and I/O controllers alongside the 8502.
George Chou was in charge of Design Methodology Service.
