LegUp 6.4 Release!

By Andrew Canis,

We are excited to announce that LegUp 6.4 has been released! You can download LegUp here.

Release Notes

New features and bug fixes for this release:

  • Fused multiply-add (FMA) support using hard floating-point DSPs on Intel Arria 10. This allows performing multiply-add (a = b*c+d) or multiply-accumulate (a += b*c) using a single hardened DSP block running at 300+ MHz.
  • Ability to control from software implementing FIFOs in registers, block RAMs, or Ultra RAMs (on Xilinx UltraScale devices)
  • Various bug fixes

Pricing

LegUp 6.4 comes with a 30-day free trial period so that you can try out the tool. Please note that during the trial period, you may only use LegUp for evaluation purposes, and the generated hardware cannot be used in a commercial product. To purchase a full license, please contact us at sales@legupcomputing.com.

Github with LegUp examples and LegUp 6.3 Release!

By Andrew Canis,

We are excited to announce that we now have a public github repository with LegUp example code to give our users a better idea of real-life example applications using LegUp:
https://github.com/LegUpComputing/legup-examples
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

World’s Fastest Cloud-Hosted Memcached: 11M+ Ops/sec at 0.3 msec Latency with a Single AWS F1

By Jongsok Choi,

We are pleased to present the world’s fastest cloud-hosted Memcached on AWS using EC2 F1 (FPGA) instances. With a single F1 instance, LegUp’s Memcached server prototype achieves over 11M ops/sec, a 9X improvement over ElastiCache, at <300 μs latency. It offers 10X better throughput/$ and up to 9X lower latency compared to ElastiCache. Please refer to our 1-page handout for more details.

If you would like a demo of the Memcached server, please contact us at info@legupcomputing.com.

LegUp 5.1 is released!

By Jongsok Choi,

We are pleased to announce that LegUp 5.1 has been released!

This release is a culmination of more than 25 man-years of research and development. Prior to this release, LegUp has had 4 major releases for academic research. During these years, LegUp has been used by thousands of researchers around the world, making it the de-facto standard in high-level synthesis (HLS) research. In 2014, LegUp won the Community Award at the International Conference on Field Programmable Logic (FPL) for contributions to HLS research. LegUp has also been shown to produce state-of-the-art hardware.
We have brought all of the best features from our previous releases, and made it even better by adding new features, as well as improving the quality of the generated hardware.

New Features

Here are just some of the highlights of what we have added for this release.

  • LegUp IDE which provides a complete development environment with a debugger and a profiler.
  • Support for Xilinx, Lattice, Microsemi, and Achronix FPGAs (LegUp previously only supported Altera FPGAs).
  • Windows OS support (LegUp previously only supported Linux OS).
  • Improved pipelining.
  • Improved memory architecture.
  • Improved user messages.

Pricing

LegUp 5.1 comes with a 30-day free trial period so that you can freely try out the tool. Please note that during the trial period, you may only use LegUp for evaluation purposes only, and the generated hardware cannot be used in a product.
