University of Toronto True Blue Expo

By Andrew Canis,

Thanks to everyone who came by and visited out booth at MaRS for the University of Toronto startup showcase! We really enjoyed talking about how LegUp Computing’s technology makes FPGAs much easier to program. I was amazed at how many startups are being spun out of the University of Toronto. We appreciate the support from the UTEST incubator and University of Toronto as we grow the company.

LegUp Seminar Talk at the University of Toronto

By Andrew Canis,

Our CEO and CTO, Andrew Canis and Jongsok Choi, gave a talk at the monthly FPGA seminar at the University of Toronto last week. We started with an overview of LegUp Computing and how FPGAs compare to CPUs. We talked about how our LegUp high-level synthesis software tool makes FPGA design easier by allowing a C/C++ input language even for system-level design. We showed off some surprising results we found for floating point cores generated with LegUp HLS compared to hand-written RTL cores. Then we showed a demo of our Memcached F1 instance using cloud FPGAs on AWS, and we gave some highlights on what it’s like to working at a startup.

Check out the youtube video of the talk below (sorry for the poor audio quality). The slides are available here.

LegUp 6.6 Release and Floating Point Multiplier Example

By Ruolong Lian,

We are excited to announce that LegUp 6.6 has been released! You can download LegUp here.

Floating-Point Multiplier Example

We’re happy to announce a new member of the team, Mehul Gupta, who has just joined the company for an internship from the University of Waterloo. He has been helping to build a floating-point library written in C++ using LegUp HLS that offers user-configurable precision (single, double, half, and arbitrary precision). The first example is a floating-point multiplier available in our public git repository:

Release Notes

New features and bug fixes for this release:

  • Generic floating-point support for all FPGA vendors. We no longer rely on vendor-provided floating point cores. The floating-point cores can be tuned to the target FPGA architecture for optimal performance and area results. Our HLS floating-point cores are shown to produce better results than hand-written floating-point IP cores.
  • Standard IP-XACT packaging file generation for LegUp cores to support integration into vendor system builder tools
  • CentOS 6+ support, LegUp Linux installer no longer requires root privileges
  • VHDL top-level wrapper generation to support integration into VHDL projects
  • Various bug fixes

LegUp 6.6 comes with a 30-day free trial period so that you can try out the tool.

LegUp 6.5 Release!

By Zhi Li,

We are excited to announce that LegUp 6.5 has been released! You can download LegUp here.

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

LegUp 6.5 comes with a 30-day free trial period so that you can try out the tool.

The main goal of the repository is to provide more design examples using high-level synthesis to help users understand the coding style needed to achieve good performance. These examples are all released using a BSD license so the code can be used for academic or commercial applications. We will add more examples to this repository over the coming months.
We are also excited to announce that LegUp 6.3 has been released! You can download LegUp here.

Release Notes

New features and bug fixes for this release:

  • Allow LLVM intermediate representation as input to allow tools such as LeFlow
  • Various bug fixes
