The SPG series is a series of systems-on-a-chip (SOCs) made by the Taiwanese company Sunplus. They are probably the most commonly used SOCs in plug-and-play game consoles other than Famiclones.

Many technical details about SPG systems are currently unknown as Sunplus releases very little public information, and barely even acknowledges the existence of the SPG series on its website. It is known that the SPG2xx series uses the µ’nSP instruction set except the 29x which uses "s+core" architecture.[1] At least the SPG29x series supports eCOS.[2]
