Introduction to C6000 DSP Optimization

• Introduction to C6000 DSP Optimization This application report helps DSP newcomers optimize their code for the C6000 family of DSPs.

C6000 Optimization Workshop and Materials

• TMS320C6000 DSP Optimization Workshop
  • The workshop materials on this page show a user how to optimize their high-level C code for the TMS320C6000 DSP.
  • Scroll down to "Workshop Materials"

c64, c64Plus Compiler Overview

• C64plus_cgt_overview.pdf‎
  • Compact instructions, sploop, trampolines, performance/codesize data for c64x+ and a very brief splattering of tuning tips

c64, c64Plus Optimization Techniques

• C64p_cgt_optimization.pdf‎
  • Selecting the right build options
  • Also adds intermediate/advanced techniques for optimizing structure accesses, using restrict with structures and new examples.
  • Examples use cgt version 6.0.x.
  • Good data on control code optimizations

Hand-Tuning Loops and Control Code on the TMS320C6000

• Detailed Application Report
  • The TMS320C6000 compiler automatically performs a great deal of performance-related tuning. This compiler-driven optimization usually suffices. For the occasional cases where additional CPU performance is needed, this application report presents strategies and examples for improving performance of C/C++ applications. Memory-related performance improvements (such as background DMA transfers or cache usage) are outside the scope of this report. The techniques apply to all members of the C6000 architecture family.
  • The target audience is intermediate to advanced application developers. Familiarity with the C6000 architecture and experience developing code for this architecture is assumed.
