8088 PDF Datasheet – 8-BIT HMOS Microprocessor

An 8-bit HMOS microprocessor refers to a microprocessor architecture that processes data in 8-bit chunks using HMOS (High-Speed Metal Oxide Semiconductor) technology. HMOS is a type of semiconductor technology known for its speed and efficiency characteristics. An 8-bit microprocessor has an 8-bit data bus, which means it can process and manipulate data in 8-bit units. These microprocessors were prevalent in the early days of computing and are still used in some specialized applications today.

One of the most famous 8-bit HMOS microprocessors is the Intel 8088, which was introduced in 1979. The 8088 was used in the original IBM PC and many other early personal computers. It had an 8-bit external data bus and a 16-bit internal architecture. The 8088 was the heart of the IBM PC’s CPU, responsible for executing instructions and managing data.
