8-bit Microprocessor

ver 1.00

OVERVIEW

Document contains brief description of DZ80

core functionality. The DZ80 is an advanced 8-

bit microprocessor with 208 bits of user acces-

sible registers, composed of six general pur-

pose registers, able to be used individually as

either 8-bit registers, or as 16-bit register pairs.

Additionally to those registers, DZ80 supports

two sets of accumulator and flag registers.

The DZ80 contains also Stack Pointer, program

Counter, two index registers, a REFRESH reg-

ister, 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 peripher-

als family.

DZ80 is fully customizable, which means it is

delivered in the exact configuration to meet

users requirements. There is no need to pay

extra for not used 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.

CPU FEATURES

Fully compatible with industry standard Z80

Fully synthesizable, static synchronous de-

sign with no internal tri-states

No internal reset generator or gated clock

Scan test ready

Technology independent HDL source code

Core can be fully customized
