Show HN: A High-Performance CRC Hardware Generator in Bluespec SystemVerilog What is it and why make it? The Cyclic Redundancy Code(CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to digital data. And blue-crc repo provides a parallel, pipelined and highly-parameterized hardware implementation of CRC targeting high-throughput applications, such as network transmission. CRC is a mature and widely-adopted error-detecting technology, and there have been numerous hardware implementations of it. However, most existing hardware designs are either implemented using pure combinational logic or are only designed to process input data byte-by-byte serially, which results in extremely low throughput. Other designs targeting high-performance applications lack proper parameterization and only support some specific CRC configurations. Blue-crc aims to solve these problems by providing both high-throughput and well-parameterized CRC hardware implementation. Main Features of Blue-CRC Complete CRC Configuration: the implementation supports complete CRC configuration parameters, including polynomial, initVal(the initial CRC value), finalXor(the result is xor’d with this value if desired), reflectData(if True, the input bit order is reversed), and reflectRemainder(if True, the result bit order is reversed). Standard Interfaces: The input interface follows AxiStream protocol, with a parameterized data width. The output CRC result is guarded by the basic handshake protocol. Parallel: The IP is designed to process multiple bytes per cycle. Fully Pipelined: The implementation takes in raw data and produces results every cycle. High Throughput: The implementation, configured with 256-bit input and 32-bit CRC output, runs at 500MHz on Xilinx xcvu9p FPGA. Have a try? For BSV users, you can import our codes and instantiate CrcAxiStream interface in your design directly. Besides, we provide a script to generate custom Verilog CRC implementation automatically. If you are interested in high-performance CRC hardware acceleration, it’s worth giving it a try. We are also open to any recommendations for further improving our designs.

Show HN: I made an in-browser code editor with code replay and REPL https://ift.tt/hHFcx9Q

Show HN: I made an in-browser code editor with code replay and REPL I made a Logicboard.com — A collaborative code editor with code-replay feature. Code-replay lets you run the coding session like a movie, I wrote a blog post on how I implemented this: https://ift.tt/UfbRuKT You can try out the demo here: https://ift.tt/4pWwF7k And play around with the code editor here: https://ift.tt/pmt2AXa Logicboard also has an REPL shell, just type "start()" and hit enter in the output area. https://ift.tt/xqSa4D0 May 27, 2023 at 12:36AM

Show HN: Private instances are the secret sauce for Unleash Hi HN, I want to share how important Private instances are for us, and how we build at Unleash. Hope you find this helpful and if you have any questions, ask away! In case you don't know - Unleash is an open source, enterprise-ready feature management solution built with privacy in mind. I would love to know your thoughts about this, and share your thoughts about Unleash or the way we build software. Questions about the setup are also welcome, if you would like to build something like this yourself! https://ift.tt/alp9dUG May 25, 2023 at 11:30PM
