Abstract
An apparatus and method for unaligned cache reads is implemented. Data signals on a system bus are remapped into a cache line wherein a plurality of data values to be read from the cache are output in a group-wise fashion. The remapping defines a grouping of the data values in the cache line. A multiplexer is coupled to each group of storage units containing the data values, wherein a multiplexer input is coupled to each storage unit in the corresponding group. A logic array coupled to each MUX generates a control signal for selecting the data value output from each MUX. The control signal is generated in response to the read address which is decoded by each logic array.
