CHIP DSP-2 Super Nintendo
Not a game
The DSP-2 can only be found in the SNES port of Dungeon Master. Its primary purpose is to convert Atari ST bitmap image data into the SNES bitplane format. It also provides dynamic scaling capability and transparency effects.
This series of fixed-point digital signal processor chips allowed for fast vector-based calculations, bitmap conversions, both 2D and 3D coordinate transformations, and other functions. Four revisions of the chip exist, each physically identical but with different microcode. The DSP-1 version, including the later 1A die shrink and 1B bug fix revisions, was most often used; the DSP-2, DSP-3, and DSP-4 were used in only one title each. All of them are based on the NEC µPD77C25 CPU and clocked at 8Mhz
