HLS Arbitrary Precision Types Library

This repo provides simulation code of HLS Arbitrary Precision Types.

The code is based from headers shipped with Vivado, but due to absence of synthesis support it should not be used in an HLS project targeting FPGA.

Compatibility

Tested with g++ (GCC) 6.2.0 on x86_64 GNU/Linux.

Usage

Include the ap_int.h or ap_fixed.h in C++ code, and set compiler option to add the path of include directory in this repo into header search directory list.

$ cd examples/ap_int
$ g++ -I ../../include/ test.cpp
$ ./a.out
a = 11.3137 (0x0b.504ea4p0)
b = 11.3137 (0x0b.504f33p0)
c = a + b = 22.6274 (0x16.a09dd7p0)
$
