View source for DSP-1

The '''DSP''' series of coprocessors '''DSP-1''', '''DSP-2''', '''DSP-3''', '''DSP-4''' were used in many games for computational support, usually to assist games with 3D features.
DSP is an acronym for "Digital Signal Processor".

The SNES CPU would write computation commands to the DSP's memory mapper registers, then read back the computed result.

Not to be confused with the [[S-SMP|S-DSP]] sound device built into the SNES.
