Release Notes

New features and bug fixes for this release:

  • Support for arbitrary bitwidth integers using the ap_uint C++ class. LegUp can now support operations on integers with more than 64 bits which wasn’t possible with our previous C-based arbitrary bitwidth datatypes.
  • AXI-Stream interfaces can also be created by using FIFOs containing structs with ap_uint elements:
#include "legup/ap_int.hpp"
 
struct axiWord {
     legup::ap_uint<128> data;
     legup::ap_uint<16> keep;
     legup::ap_uint<1> last;
};

void kernel(legup::FIFO<axiWord> &input_fifo, legup::FIFO<axiWord> &output_fifo) {
     axiWord currWord = input_fifo.read();
     if (currWord.last) currWord.data += 10;
     output_fifo.write(currWord);
}
  • Co-simulation supports the new ap_uint types.
  • Various bug fixes
