CoCo: A Hardware/Software Platform for Rapid Prototyping of Code Compression Technologies

摘要

In recent years instruction code compression/decompression technologies have emerged as an efficient way to a) reduce the memory usage of an embedded system, b) to improve performance through effectively higher bandwidths and/or to c) reduce the overall power consumption of a system processing compressed code. We have presented efficient code compression/decompression techniques and architectures in the past. For the commercialization phase, we designed a novel hardware/software code compression/decompression platform (CoCo). It consists of a software platform that prepares, optimizes, compresses and compiles instruction code and a generic, parameterizable FPGA-based hardware architecture in form of a hardware platform that allows to rapidly evaluate prototypes of diverse compression/decompression technologies. We show the flexibility of CoCo, its ability to achieve code compression ratios (parameterizable) of up to 50% with a slight system performance gain and its ability to apply compression on real-world compiled code without any limitations where others have made implicit software-restrictive assumptions.
