The DSP series of coprocessors. DSP-1 was used in many games for computational support, often to assist games with 3D features. DSP-2, DSP-3, and DSP-4 were used in a single game each. This family of chips shares a similar interface, but they differ in their command functions.
The SNES CPU would write computation commands to the DSP's memory mapper registers, then read back the computed result.
DSP is an acronym for "Digital Signal Processor", but the name seems poorly chosen. It does not operate on a continuous signal like most DSPs.
Not to be confused with the S-DSP sound device built into the SNES.
