Abstract
Time constraints and cost are the major limitations
for developing optimized DSP based solutions for the
consumer market. Exploiting the DSP architecture and
software development tools with various optimization
techniques can lead to the desired performance goals.
Developing a highly optimized with more features in
the shortest possible time gives an edge over the competitors.
Optimization helps to cut the cost (processing power
and memory) of an existing product or helps to introduce
more features and more functionality with the same cost.
A cost effective solution requires employing optimization
not only in its constituent components but also in total.
This paper presents optimization techniques for execution
speed and memory in general and specific to Texas Instruments’
TMS320C6x series of DSP processors. Texas Instruments’
optimizing C compiler does most of the desired optimization
in C. At the heart of the compiler based optimization
techniques is tuning the C code to give maximum information
about the code to the compiler enabling the compiler
to do maximum optimization. An assembly based solution
should be used only when the compiler is unable to exploit
the full resources of the C6x CPU.
