C2H Compiler Concepts
The accelerator's connections are managed by the C2H Compiler. You can
manually customize the connections using pragma directives in the
accelerated C code. Chapter 6, Pragma Reference , describes
C2H Compiler pragma usage. You cannot edit the accelerator's
connections in the SOPC Builder GUI.
Generation of a Hardware Accelerator
The C2H compilation flow shares commonalities with a conventional C
compiler, but the scheduling of statements, optimization, and object
generation is different. When generating a hardware accelerator, the
C2H Compiler does the following:
1.
2.
3.
4.
5.
6.
7.
Runs the GNU GCC preprocessor to evaluate macros, includes, and
other preprocessing directives.
Parses code.
Creates a graph of data dependencies.
Performs some optimizations.
Determines the best sequence in which to perform each operation.
Generates an object file for the hardware accelerator. This object file
is a synthesizable HDL file.
Generates a C wrapper function that isolates and hides the details of
how the Nios II processor interacts with the hardware accelerator.
The wrapper function is a C file that replaces the original C function
at software link time.
The generated accelerator logic includes the following:
One or more state machines that manage the sequence of operations
defined by the C function. On any clock cycle, an arbitrary number
of computations and memory accesses can happen simultaneously,
orchestrated by the state machines.
One or more Avalon Memory-Mapped (Avalon-MM) master ports,
which fetch and store data as required by the state machines.
An Avalon-MM slave port and a set of memory-mapped registers
that allow the processor to set up, start, and stop the accelerator.
