Fan Peck Ling, Fung Kah Khuen, Damu Radhakrishnan · 2002
The design of an audio processor card for generating special sound effects is presented. This is designed as an add-on card that plugs directly into the ISA bus of a PC. The card uses a Motorola DSP processor, DSP56001, for audio signal processing. External SRAM modules are used for program and data storage. A codec chip is employed to handle the digital interfacing between the DSP processor and the analog audio world.
