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.
Zilog, Inc. is an American manufacturer of microprocessors, microcontrollers, and application-specific embedded system-on-chip (SoC) products. The company was founded in 1974 by Federico Faggin and Ralph Ungermann, who were soon joined by Masatoshi Shima. All three had left Intel after working on the 4004 and 8080 microprocessors.
The Zilog Z8000 is a 16-bit microprocessor architecture designed by Zilog and introduced in early 1979. Two chips were initially released, only differing in the width of the address bus: the Z8001 (23-bits) and Z8002 (16-bits).
The basic architecture, a modified (non-strict) Harvard architecture, is technically very different from the Zilog Z80. Despite this, the instruction set and assembly language syntax are quite similar to other Zilog processors: Load/store operations use the same LD mnemonic (no MOV or MOVEs), typifying instructions such as DJNZ, are the same ...
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 ...
The Zilog Z180 is an 8-bit microprocessor designed by Zilog as a successor to the Z80. It is compatible with the large base of software written for the Z80. [ 1 ] The Z180 family adds higher performance and integrated peripheral functions like clock generator, 16-bit counters/timers, interrupt controller, wait-state generators, serial ports and ...

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. It covers more general concepts, such as information representation and data structures, and describes in detail topics specific to the Zilog Z80 microprocessor, such as ...
