DSP1
From SnesLab
DSP1 in an enhancement chip with part number 22943 that implements common 3D math operations.
The DSP1 has registers named DR and SR.
The following commands are supported:
- DSP1/Attitude
- DSP1/Distance
- DSP1/Gyrate
- DSP1/Inverse
- DSP1/Multiply
- DSP1/Objective
- DSP1/Parameter

- DSP1/Project
- DSP1/Radius
- DSP1/Range
- DSP1/Raster
- DSP1/Rotate
- DSP1/Scalar

The DSP1 hardware supports DMA, but the SNES does not have a way to kick it off. [2]
In Figure 3-1-1 of the manual, the connection between the DSP1 chip and the 62-pin cartridge slot incorrectly appears outside the game pak.[3]
