Abstract :
To overcome the shortcoming of time-consuming digital signal processing functions performed in a NS32016 microcomputer system, the TMS32010 serves as an independent numeric processor to implement the numeric processor to implement the numeric intensive algorithms. Hardware developments including direct memory expansion and extended memory interface are presented. Also, ADC (analog-to-digital conversion) and DAC (digital-to-analog conversion) are provided by this system to perform various DSP (digital signal processing) applications. Software development of this enhanced DSP system can be expanded to various applications. Some demonstration programs including an FIR bandpass filter, an IIR low-pass filter, and a rotation (graphics) application were used to test the system.<>
