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.
