The amazing multi-processor 8-bit microcomputer, featuring Z80, 6502 and AVR processors. Built with CPLDs, CERBERUS 2100™ is fully programmable even with respect to its hardware, at the individual gate and flip-flop level. • CERBERUS 2100TM is an innovative, fully- functional computer, not a toy • It is an open-source educational platform for students of electronics and computer engineering • It gives the user direct, convenient and unrestricted access to the hardware • It allows for easy hardware changes and experimentation through in-system reprogramming of three CPLDs • Its BIOS is an Arduino AVR sketch written in C, thus very easy to edit • Its architecture is highly modular, allowing for compartmentalized, safe experimentation • CERBERUS 2100TM aims to demystify computers by showing in detail how one is built, down to single gates and flip-flops • Its architecture illustrates how a multi- processor system—with expansion possibility for even more processors— can be built • Its design was done explicitly at the gate-level, with no high-level hardware synthesis tools • CERBERUS 2100’s architecture is clean and very easy to understand • Two BASIC interpreters: one for the Z80 and the other for the W65C02S CPU
