Abstract: A method for outputting alternative instruction sequences. The method includes tracking repetitive hits to determine a set of frequently hit instruction sequences for a microprocessor. A frequently miss-predicted branch instruction is identified, wherein the predicted outcome of the branch instruction is frequently wrong. An alternative instruction sequence for the branch instruction target is stored into a buffer. On a subsequent hit to the branch instruction where the predicted outcome of the branch instruction was wrong, the alternative instruction sequence is output from the buffer.

Abstract: Instructions are grouped into instruction groups based on optimizations that may be performed. An instruction is obtained, and a determination is made as to whether the instruction is to be included in a current instruction group or another instruction group. This determination is made based on whether the instruction is a candidate for optimization, such as decode time instruction optimization. If it is determined that the instruction is to be included in another group, then the other group is formed to include the instruction.

Abstract: Systems and methods for implementing certain load instructions, such as vector load instructions by cooperation of a main processor and a coprocessor. The load instructions which are identified by the main processor for offloading to the coprocessor are committed in the main processor without receiving corresponding load data. Post-commit, the load instructions are processed in the coprocessor, such that latencies incurred in fetching the load data are hidden from the main processor. By implementing an out-of-order load data buffer associated with an in-order instruction buffer, the coprocessor is also configured to avoid stalls due to long latencies which may be involved in fetching the load data from levels of memory hierarchy, such as L2, L3, L4 caches, main memory, etc.
