Acorn - 1

EDA platform : ispADVANCED

design type : VHDL 87

　

 Description

*Acorn-1 is very similar to PopCorn-1. It is so similar that given the choice, I'd choose PopCorn-1 over this design. Ok, so then why designed this one ? It actually was a class project.

*Architecturally it is CISC, with somewhat minimmal instruction set.

*16Kbyte of address space.

*Support 1 edge triggered interrupt.

*Fits nicely in one Altera 10K20 FPGA. You can even embed with code and enough variable RAM using the Altera's EAB (embbeded array block)

Documentation

to come soon, in the mean time this is the instruction set summary: instruction.doc
