The Nintendo SA-1 (Super Accelerator 1) is a microprocessor developed by Nintendo for use in Super Nintendo Entertainment System (SNES) game cartridges. A microprocessor incorporates most or all of the functions of a Central processing unit (CPU on a single Integrated is a Multinational corporation headquartered in Kyoto Japan founded on The Super Nintendo Entertainment System or Super NES (also called SNES and Super Nintendo) is a 16-bit Video game console that was At its base, the SA-1 is an upgraded 65816-compatible coprocessor that runs alongside the SNES's 5A22 CPU (also a 65816-based processor). The WDC 65816 (also 65C816) a 16-bit Microprocessor CPU developed by the Western Design Center (WDC, is an expanded and compatible A coprocessor is a Computer processor used to supplement the functions of the primary processor (the CPU The Ricoh 5A22 is the Microprocessor CPU produced by Ricoh for the Super Nintendo Entertainment System (SNES video game console The coprocessor scheme allows the game console to process data faster.

The SA-1 as used in the SNES is not a slave CPU for the 5A22; both can interrupt each other independently. In Computing, an interrupt is an asynchronous signal from hardware indicating the need for attention or a synchronous event in software indicating the need for a change

Major features

The Nintendo SA-1 features a wide range of enhancements over the standard 65816:

• Upgraded 10 MHz clock speed, up from a max of 3. The hertz (symbol Hz) is a measure of Frequency, informally defined as the number of events occurring per Second. The clock rate is the fundamental rate in cycles per second (measured in Hertz) at which a Computer performs its most basic operations such as adding two 58 MHz
• Faster RAM
• Memory mapping capabilities
• Limited data storage and compression
• New DMA modes such as bitmap to bitplane transfer
• Built-in CIC lockout, for piracy protection and regional marketing control
