Abstract
Cache layout is simplified by swizzling the bits of instruction words. Then the words are read out of cache by using a shuffled bit stream which simplifies cache layout. The object is further met using a cache structure which includes a device for storing a shuffled instruction stream; and a device for multiplexing bits from the storage means onto the bus so that the bits are deshuffled. The multiplexing means includes a multiplicity of lines leading from the storage device to the bus. The read lines do not cross each other.
