During a compressing portion, memory (20) is divided into cache line blocks (500). Each cache line block is compressed and modified by replacing address destinations of address indirection instructions with compressed address destinations. Each cache line block is modified to have a flow indirection instruction as the last instruction in each cache line. The compressed cache line blocks (500) are stored in a memory (858). During a decompression portion, a cache line (500) is accessed based on an instruction pointer (902) value. The cache line is decompressed and stored in cache. The cache tag is determined based on the instruction pointer (902) value.
