1. Introduction to the
C2H Compiler
The Nios ? II C-to-Hardware Acceleration (C2H) Compiler is a tool that
allows you to create custom hardware accelerators directly from ANSI C
source code. A hardware accelerator is a block of logic that implements a
C function in hardware, which often improves the execution performance
by an order of magnitude. Using the C2H Compiler, you can develop and
debug an algorithm in C targeting an Altera ? Nios II processor, and then
quickly convert the C code to a hardware accelerator implemented in a
field programmable gate array (FPGA).
The C2H Compiler improves the performance of Nios II programs by
implementing specific C functions as hardware accelerators. The
C2H Compiler is not designed to create arbitrary hardware systems from
C code. Rather, the C2H Compiler is a tool for generating a hardware
accelerator module, functionally identical to the original C function, that
offloads and enhances the performance of the Nios II processor.
User Guide
This user guide comprises the following chapters:
Overview
Chapter 1, Introduction to the C2H Compiler provides a detailed
background on the C2H Compiler and the concepts required to use
it.
Chapter 2, Getting Started Tutorial provides hands-on instructions
that teach you the first steps to begin using the C2H Compiler.
Chapter 3, C-to-Hardware Mapping Reference provides reference on
how the C2H Compiler translates C constructs to hardware
structures.
Chapter 4, Understanding the C2H View helps you use the C2H
view to get performance information and to control the compilation
of accelerators.
Chapter 5, Accelerating Code Using the Nios II Software Build Tools
Command Line explains how to use the C2H Compiler with the
Nios ? II software build tools.
Chapter 6, Pragma Reference summarizes usage of all C2H #pragma
directives.
Chapter 7, ANSI C Compliance and Restrictions documents all
sections of the ANSI C specification that the C2H Compiler does not
support.
