Advanced 8-bit microprocessor

Overview

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 register pairs. Additionally, DZ80 supports two sets of accumulator and flag registers. The DZ80 contains also Stack Pointer, program Counter, two index registers, a REFRESH register and an INTERRUPT register. All output signals are fully decoded and timed, to control standard memory or peripheral circuits. The DZ80 is supported by a wide range of peripherals.
DZ80 is fully customizable - it is delivered in the exact configuration, to meet user's requirements. There is no need to pay extra, for unused features and wasted silicon.
It includes fully automated testbench with complete set of tests, allowing easy package validation, at each stage of SoC design flow.
