PN22: Intro to Field Programmable Gate Arrays
An FPGA is one step more general than a CPU, it's a reconfigurable grid of configurable boolean gates and routing logic, and you can reload the configuration anytime you want.
While previously expensive and only usable with expensive closed source tools, FPGAs are now affordable and have open source toolchains.
Programming an FPGA is a bit like programming and a bit like circuit design, find out how in this presentation!
I'll be demonstrating the open source yosys toolchain used with an ice40 series FPGA.
