This article explores the concept of a ROM or Read-Only-Memory circuits. Today, the venerable ROM chip is rare, largely replaced by updateable non-volatile storage devices like flash memory. Before the age of flash updateable firmware, most consumer electronic devices had their data and code permanently encoded in one or more chips. If you needed to […]

You may have heard about SystemVerilog. And if you have, maybe you have also heard that SystemVerilog is simply an extension of Verilog, focused on testing and verification. That is both partly true and partly false. Let’s explore this a bit further to learn why that is the case. A brief history of SystemVerilog As

It is back to FPGA topics for this next article. This time we are going to be exploring register files. A register file is nothing more than an array, collection or “file” of registers. We have encountered registers before, first when I introduced sequential circuits and the Verilog reg keyword. A register is nothing more

I am taking a short break from FPGA topics because I want to introduce you to Firth. Firth is an experimental programming language heavily inspired by Forth. Its design goals are to be small, fast and efficient, portable and embeddable. Forth was designed by Charles Moore in 1968 to be a procedural, stack-oriented programming language
