Using unmodified C code in HLS tool (CtoS or Stratus)

Hi,

     I would like to know if is possible to synthesize unmodified C code in CtoS or Stratus.

     Looking at Cadence community and documentation, I found the following statements:

     1 - "The main input language is SystemC, but CtoS also offers the capability to read in C/C++ functions in which you can then choose a built-in TLM lib interface/transactor and CtoS automates the generation of the SystemC wrapper." (by Mark Warren - Forum at Cadence Online Support)

     2 - "The Cadence C-to-Silicon Compiler accepts most built-in and user-defined data types for C, C++, and SystemC... Pointers are fine to use as long as CtoS can determine what they will be pointing to... We have a "Preparing Models for CtoS" Application Note that goes into further details. Please contact your local Sales rep or AE." (by Mark Warren - Forum at Cadence Online Support)

     3 - "CtoS provides a way to use pure C/C++ as input. It is not recommended for complex designs with crucial interface requirements, but it is intended to ease the introduction to SystemC." (Section 5.1.2 in CtoS User Guide)

     Considering the simple array multiplication presented below. Is there a way (documentation or example) to automate HLS flow and use unmodified C code over CtoS/Stratus? Or I should at least make some handcode modifications as illustrated in Section "Example of Design Code Transformation" in Stratus HLS User Guide? ("This section shows the transformation​ of an algorithm written in C to an SC_MODULE that can be synthesized using Stratus HLS.")

     Thanks!

- Array multiplication

#include <stdio.h>
#define N 16

void array_mult(int a[N], int b[N], int c[N]){
  int i;
  for (i=0; i<N; i++)
    c[i] = a[i] * b[i];
}

int main(){
  int i, a[N], b[N], c[N];

  for(i=0; i<N; i++){
    a[i] = i;
    b[i] = i;
  }

  array_mult(a, b, c);
  return 0;
}
