INTRODUCTION TO THE DELFINA DSP
1. What is Delfina DSP?
Delfina DSP is a multifeatured audio board containing a 40MHz Motorola
56002 Digital Signal Processor. The board is capable of 16bit stereo
digitizing and playback at 48kHz, and it has 192kB of dual ported SRAM
memory, high speed RS232 and Centronics interfaces. The price will be
under $700, with an introductionary price for the Internetters at $400.
