Usually, designing a CPU is a lengthy process, especially so if you’re making a new ISA too. This is something that can take months or even years before you first get code to run. But what if it ...

The DZ80 is an advanced, 8-bit microprocessor, with 208 bits of user-accessible registers. It is composed of six general purpose registers, which can be used individually, as either 8-bit or 16-bit ...

The W65C02S IP is a 8/16-bit 65xx Microprocessor available in GDSII Hardcore, RTL Softcore, and FPGA Specific Firm Cores. It is software compatible with the 8-bit NMOS and CMOS 6500-series ...

[c0pperdragon] set himself the task of designing a very capable 8-bit CPU using just 74HC type logic chips on a large plug-in breadboard. To emphasize the “bread” theme, he put the whole thing ...

The processor and its peripherals had to be available ... We chose the 8088 because of its 8-bit data bus. The smaller bus saved money in the areas of RAM, ROM, and logic for the simple system.

Microcontrollers exist in almost everything, but can RISC-V satisfy the needs of this market? Is it small enough to replace 8-bit processors? What might help people migrate to a more modern processor ...
