S+core architectureEdit

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).[1]

It was supported by the Linux kernel since version 2.6.32[2] until version 4.17.[3]

Company informationEdit

Sunplus Technology is a fabless design company based in Taiwan. The company's chief executive is Sun Ching-jie.[4]

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.

In 2007, HP released the HP 35s, a calculator that uses the SPLB31A/GPLB31A.[5]

George Chou was in charge of Design Methodology Service.[6]

S+core is Taiwan's first 32bit embedded processor design and has commercial success.[4][1]
