compiler can accelerate practically any ANSI C code, can it accelerate C library functions like printf()?
A. The Nios II processor C2H acceleration compiler can accelerate C library functions, but a better question is “what functions should it be used to accelerate?” The Nios II processor C2H acceleration compiler is designed for use in computationally challenged algorithms typically found in signal processing, image processing, and packet processing applications. Typical candidates include C subroutines that consist of tight loops that transform blocks (or streams) of data; in other words, code that can benefit from parallel access to memory and requires many CPU clock cycles to complete each calculation. These subroutines typically consist of dozens of lines of code, not thousands of lines of code.
