perform memory accesses. It also requires a multiplier and a barrel shifter
to perform the right shift operation. The pragma statements inform the
C2H Compiler that the input data is stored in a memory called
onchipRAM1 and the output data is to be stored in onchipRAM2. When
the C2H Compiler compiles this function, the Nios II IDE generates a
build report as shown in
