Overview - Super Nintendo Entertainment System
Three Main Processing Units:
żSplit into PPU1 & PPU2
Central Processing Unit: Ricoh 5A22
ż1 word per instruction: 1-byte opcode, 0-3 byte operandCentral Processing Unit: Bus Connections

ż512 x 224 and 521 x 476 also possible through interlaced graphics żModes use different combinations of backgrounds and palettes żCertain modes are dedicated to scrolling, scaling, and rotationPicture Processing Unit - Example of Mode 1
Mode 1 uses:

sometimes with the game cartridgeGame Pak
żBattery-backed SRAM for saving the game's state żAdditional RAM to supplement the console's native RAM żEnhancement chips to operate in-parallel with the native processors żData transfer speed between the console and the cartridge żCurrent limit of the console to supply power to the cartridgeGame Pak - Enhancement Chips
Design Philosophy: Allow cartridges to interface supporting hardware rather relying solely on an expensive CPU that would become obsolete in a few years Game Pak with DSP-1 Game Pak with SA-1 Game Pak with Super FXEnhancement Chips: Super FX
Enhancement Chips: DSP-1
transformations scaling, and rotationEnhancement Chips: Super Accelerator 1 (SA1)
ż10.74 MHz clock speed
żFaster RAM and 2kB of internal RAM
żMemory-mapping capabilities
żBitmap to bitplane transfer
żPPU-synched hardware timers

Use of SNES Architecture (2000's and beyond)
simulate the behavior of the console żSome designed for accuracy, while others designed for modern performance żUsed modern hardware to mimic the behavior of the SNES żNo cartridges; stored game data on internal memory żCame with additional features such as save-states on-command żSeveral online documents preserved 15+ years after its lifespan for hardware modifications, software development using the 65c186 ISA, or simulated recreations of the architecture (Arduino & other microprocessors, FPGAs, etc.)References
