Abstract:
A clustered superscalar processor for reducing the miss rate of a register cache and reducing the possibility of miss penalties. The processor checks before storing an instruction in an instruction window whether there is a data dependency relationship between the instruction that will be stored in the instruction window and a previous instruction stored in the instruction window. When there is a data dependency relationship, the execution result of the previous instruction of one cluster is communicated to a register cache of another cluster that executes the instruction having a data dependency relationship with the previous instruction.
