In this paper, the authors present a code compression and on-the-fly decompression scheme suitable for coarse-grain reconfigurable technologies. These systems pose further challenges by having an order of magnitude higher memory requirement due to much wider instruction words than typical VLIW/TTA architectures. Current compression schemes are evaluated. A highly efficient and novel dictionary-based lossless compression technique is implemented and compared against a previous implementation for a reconfigurable system. This paper looks at several conflicting design parameters, such as the compression ratio, silicon area, latency, and power consumption.
