The Z80, 180, and 380 processor families represent three generations of upward-compatible µPs. The Z80 includes 150 instructions, many of which have numerous variants for operand location and ...

Toshiba's TLCS-90 incorporates the basic Z80 instruction set in an 8-bit µC with various peripherals. Unlike the Z80, which is a µP, the TLCS-90 can execute code from on-chip ROM and RAM. The µCs ...

This project implements an emulator for the Zilog Z80 microprocessor, written in C. The goal is to provide an educational and functional base to understand the internal workings of this classic ...

So, I'm curious about the Intel aspect of this. . . The 8-bit Z80 microprocessor was designed in 1974 by Federico Faggin as a binary-compatible, improved version of the Intel 8080 with a higher clock ...

This chapter focuses on perhaps the most important characteristic of an ISA (Instruction Set Architecture), which is a processor's instruction set. It defines and proposes how to classify instructions ...

Abstract: Microprocessor system is a must know subject in electrical engineering. Despite of learning through simulation, student, especially in polytechnic, have to be more involved in the hands on ...

40 years ago today, Intel Corporation introduced the 4004, the world’s first commercially available microprocessor. The 2,300 transistor device was made on a 10µm process in 1971 for Japanese ...

Why it matters: Zilog is retiring the Z80 after 48 years on the market. Originally developed as a project stemming from the Intel 8080, it eventually rose to become one of the most popular and widely ...

While using the generated Z80 tests for testing my Z80 emulator, I discovered a couple of discrepancies in the timings of certain instructions tested in the generated cases in comparison to floooh's ...
