Webb17 juli 2024 · Using a CPLD or FPGA for programmable logic is often a better choice as you have a broader range of functionality in a smaller footprint. Most CPLDs implement sum-of-product combinatorial logic and optional flip-flops for logic operations. The use of combinatorial logic function supports wide fan-in. csx slack

Webb12 mars 2024 · ManCloud, in collaboration with Seewood and derKevin, have designed a new modchip for the Nintendo Gamecube. This modchip utilizes a Complex Programmable Logic Device (CPLD) which is similar to an FPGA, and was inspired by an older Gamecube modchip called the Shuriken Attack. Webb26 apr. 2024 · In addition to an expensive toolset, the Lattice CPLDs have 1.8V cores, and just 10yrs data retention instead of 20. So the real choice was between an small FPGA (Lattice parts are better in this intermerdiate range) and an obsolete CPLD. So DDuck is right, in my opinion. \$\endgroup\$ – Webb21 dec. 2024 · The interface comprises a Raspberry Pi Zero and a specially designed Hat containing a small CPLD. Custom firmware on the Raspberry Pi, in conjunction with the CPLD, is able to correctly sample each of the Beeb's video modes to give a pixel-perfect rendition.
