The Zilog Z80 is an 8-bit microprocessor designed by Zilog that played an important role in the evolution of early computing. Launched in 1976, it was designed to be software-compatible with the Intel 8080, offering a compelling alternative due to its better integration and increased performance.
The HD64180 is a Z80-based embedded microprocessor developed by Hitachi with an integrated memory management unit (MMU) and on-chip peripherals. [1] It appeared in 1985. [ 2 ] The Hitachi HD64180 "Super Z80" was later licensed to Zilog and sold by them as the Z64180 and with some enhancements as the Zilog Z180 .
In order to do so, the CPU has a full 24-bit address mode called ADL mode. In ADL mode, all Z80 16-bit registers are extended to 24 bits with additional upper 8-bit registers. For example, the HL register pair is extended with an uppermost register called HLU. The resulting 24-bit multi-byte register is collectively accessed by its old name, HL.
The company's most famous product is the Z80 microprocessor, which played an important role in the evolution of early computing. Software-compatible with the Intel 8080, it offered a compelling alternative due to its lower cost and increased performance, propelling it to widespread adoption in video game systems and home computers during the ...
Programming the Z80 is a seminal computer programming text, written by Rodnay Zaks and first published in 1979 by Sybex. It is designed as both an educational text to teach programming techniques of elementary to intermediate level using assembly language , and as a self-contained reference book.
The Zilog Z800 was a 16-bit microprocessor designed by Zilog and meant to be released in 1985. It was instruction compatible with their existing Z80, and differed primarily in having on-chip cache and a memory management unit (MMU) to provide a 16 MB address range. It also added a huge number of new more orthogonal instructions and addressing ...
R800. The R800 is the central processing unit used in the MSX Turbo-R home computer.The R800 was designed by ASCII Corporation of Japan and built by Mitsui & Co The goal was a modern and pipelined CPU binary compatible with the Z80, and therefore with MSX software, while also maintaining compatibility with older MSX Z80-based hardware.
Build Your Own Z80 Computer: design guidelines and application notes is a book written by Steve Ciarcia, published in 1981 by McGraw-Hill.. The book explains step-by-step the process of building a computer from the ground up, using the Zilog Z80 8-bit Microprocessors, including building a power supply, [1] keyboard, and interfaces to a CRT terminal and tape drive.
