Section 6.9. Summary


6.9. Summary

In this chapter we have explored how FPGA hardware, in the form of hardware description language files, is created by the Impulse C compiler. We have also seen how these hardware processes may be connected to external hardware components, using a VHDL test bench for demonstration purposes. And lastly, we have explored some of the language-level optimizer controls available to you as an Impulse C program and have shown (briefly) how cycle-accurate debugging can be accomplished using a hardware simulator.

The chapters that follow spend more time exploring important topics related to hardware generation and optimization, using a series of examples as the basis for discussion. First, however, it is important for us to examine in more detail the statement-level optimizations available to you and to describe how certain programming techniques can help increase application performance.

Learn the latest about hardware generation

The structure of hardware descriptions created by the Impulse C compiler depends on many factors, including the coding style used (in particular, how stream reads and writes are specified), the target platform, and the version of the hardware generator and/or optimizer. Changes are being made to the software at a rapid pace. For a more complete understanding of the generated hardware structure, you may want to visit the Impulse C online discussion forums at www.ImpulseC.com/forums.
