Abstract

Subleq (Subtract and Branch on result Less than or Equal to zero) is both an instruction set and a programming language for One Instruction Set Computer (OISC). We describe a hardware implementation of an array of 28 one-instruction Subleq processors on a low-cost FPGA board. Our test results demonstrate that computational power of our Subleq OISC multi-processor is comparable to that of CPU of a modern personal computer. Additionally, we provide implementation details of our complier from a C-style language to Subleq.
