We propose a new variable-sized-block method for VLIW code compression. Code compression traditionally works on fixed-sized blocks and its efficiency is limited by the small block size. Branch blocks-instructions between two consecutive possible branch targets-provide larger blocks for code compression. We propose LZW - based algorithms to compress branch blocks. Our approach is fully adaptive and generates coding table on-the-fly during compression and decompression. When encountering a branch target, the coding table is cleared to ensure correctness. Decompression requires only a simple lookup and update when necessary. Our method provides 8 bytes peak decompression bandwidth and 1.82 bytes in average. Compared to Huffman's 1 byte and V2F's 13-bit peak performance, our methods have higher decoding bandwidth and comparable compression ratio. Parallel decompression could also be applied to our methods, which is more suitable for VLIW architecture.
