This document is the user guide of Altera's Nios II C2H compiler
The Nios II C-to-Hardware Acceleration (C2H) Compiler is a tool that allows users 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).
It is a tool that allows you to create custom hardware accelerators directly from ANSI C source code.
It implements specific C functions as hardware accelerators, which often improves execution performance by an order of magnitude.
