Abstract

This note discusses some fixed-point concepts, from number representation to several real-time applications in DSP. Analog Devicesí DSP chip will be used in the discussion and compared to the Texus Instrument C67 and C32. Readers should understand the big picture of fixed-point representation, the architecture, instruction sets, stack, circular buffer, and C-callable of the ADSP-2100.
