Unit-Generator Implementation on the NeXT DSP Chip

The Motorola DSP56001 is a state-of-the-art digital signal processing chip that can execute (with the clock at 25 MHz) 12.5 million instructions per second and, in a single instruction, can perform a 24 by 24-bit multiply, a 48 plus 56-bit addition, two parallel data moves, an instruction fetch and decode, and two general index updates. The 24-bit data paths and computational architecture make the DSP56001 exceptionally well suited for real-time digital audio synthesis.
