Abstract
A parallel processing unit operable in a delayed branch method has a branch-delay slot filled with instructions to be executed when a branch by a branch instruction is taken. The instructions in the branch-delay slot are those fetched in a period from fetching of the branch instruction till the execution of the branch instruction. Instructions are prefetched from an instruction memory into a queue memory. The queue memory includes a plurality of blocks of storage units. Instructions in the same block as a branch instruction and subsequent to the branch instruction, and instructions in the block adjacent to the block including the branch instruction provide the branch delay slot for the branch instruction. A parallel processing unit operable in a predicted branch method includes a queue memory including a plurality of entries, each of which includes an instruction and a flag indicating that an associated instruction is executed according to a prediction of a branch. This flag is utilized to control execution and non execution of an associated instruction.
