Calculation Of TMS320C5x Power Dissipation
The power supply current requirements for the 16-bit fixed-point TMS320C5x digital signal processor (DSP) depend not only on the device functionality, but also on the system parameters. This document describes the techniques for analyzing the system and device operating current levels. Once these factors are determined the power dissipation can be calculated followed in turn by the device thermal

Minimizing Quantization Effects Using the TMS320 DSP Family
Due to its discrete nature, DSPs represent variables and performs arithmetic functions with a finite word length. This produces three effects: the selection of filter transfer functions is quantized with filter poles and zeros existing only at specific locations in the z plane; the input is quantized; and noise is introduced from DSP multiplication and division operations. This document shows how

Setting Up TMS320 DSP Interrupts in 'C'
Four steps are required to set the TMS320 DSP interrupts: create a interrupt service routine, initialize the vector table and set the memory map, enable the interrupts in the CPU, and enable the interrupt sources. This document shows how to set the interrupts in C, C callable assembly, or in-line C. Sample C code segments are provided. The appendix gives complete examples for setting interrupt vec
