A dramatic effect of optimization in DSP processors is rather than complicating the code, compiler optimization can often clarify it. Figure 1 shows a simple loop in C and the output of the compiler. ...

In this special guest feature, James Reinders describes why roofline estimation is a great tool for code optimization in HPC. "As a long-time teacher of optimization techniques, I can confidently say ...

Optimizing code, therefore, begins with choosing the right algorithm for the target DSP. It is necessary to set a clear, reasonable optimization goal that takes into account the underlying ...

With the optimizing option activated, the Diab-Data compiler will automatically generate code from Listing 1 to use the fast auto-incrementing instructions without the necessity of "persuasion" by ...

The code works by using a hardware timer to trigger an interrupt. After calculating the next time it should run again, and changing the state of the data line, the code just sits quietly until it ...

Code was developed for the Power () subroutine using the White Mountain VisualDSP compiler with all optimization deactivated. This SHARC code will run much faster than the equivalent 68k code.

Fortunately, highly efficient C compilers are appearing today that not only make the parallelism more manageable, but also save vast amounts of time by automating the optimization of code size and ...
