Fifty years ago, Hewlett-Packard introduced the first handheld scientific calculator, the HP-35. It was quite the engineering feat, since equivalent machines of the day were bulky desktop affairs, if not …read more Continue reading Remoticon 2021 // Rob Weinstein Builds an HP-35 from the Patent Up
The list of requirements for hosting one of our weekly Hack Chats is pretty short: you’ve got to be knowledgeable, passionate, and above all else, willing to put those two …read more Continue reading Al Williams Tells All in the Logic Simulation Hack Chat
Building your own computer has many possible paths. One can fabricate their own Z80 or Motorola 6502 computers and then run a period correct OS. Or a person could start …read more Continue reading Homebrew 16 Bit Computer Reinvents All The Wheels
VHDL and Verilog are hardware description languages, used to describe and define logic circuits. They’re typically used to design ASICs and to program FPGAs, essentially using software to define hardware. …read more Continue reading Using VHDL To Generate Discrete Logic PCB Designs
We are accustomed to seeing RISC-V implementations in Verilog or VHDL, but [Low Level JavaScript] has one in TypeScript. Before you dismiss it as a mere emulator, know that the …read more Continue reading RISC-V in… Typescript?
A recent trend has been to convert high-level constructs into FPGA code like Verilog or VHDL. Slice goes the other way: it converts very hardware-specific concepts to Verilog and aims …read more Continue reading Slice Your Next FPGA Design
Digital filters are always an interesting topic, and they are especially attractive with FPGAs. [Pabolo] has been working with them in a series of blog posts. The latest covers an …read more Continue reading FIR Filters for Xilinx
We were always envious of Star Trek, for its computers. No programming needed. Just tell the computer what you want and it does it. Of course, HAL-9000 had the same interface and that didn’t work out so well. Some researchers at NYU have taken a natural language machine learning system …read more

For most people, adding WiFi to a project means grabbing something like an ESP8266 or an ESP32. But if you are developing your own design on an FPGA, that means adding another package. If you are targeting Linux, the OpenWifi project has a good start at providing WiFi in Verilog. …read more
There’s a lot of argument over which was the first modern computer to be built. There’s room for debate, but EDSAC — the work of Dr. Maurice Wilkes — certainly was among the first. While we’ve seen simulators before, [hrvach’s] FPGA-based simulator for the MiSTer platform has a lot going …read more
