Abstract: There is provided a system and method of prefetching array segments. A prefetcher management unit (PMU) is disclosed. The PMU includes an interface to interact with programs via an application programming interface (API) and one or more data structures configured to store a plurality of addresses, each of the plurality of addresses representing a memory location of data stored in an array segment. The PMU also includes a prefetcher interface configured to use an address in the one or more data structures to instruct a prefetcher to prefetch data into a cache and a load-store unit interface configured to use the address in the one or more data structures to instruct a load-store unit to load data from the cache.

Abstract: A method of branch prediction includes, in a pre-execute loop, loading a series of instructions leading to a load dependent branch (LDB) instruction including a load instruction, executing the load instruction to receive a part of a branch condition, computing a branch outcome of the LDB instruction based on the branch condition, and storing the branch outcome to a branch-outcome memory. Then, in a main loop corresponding to the pre-execute loop, loading the LDB instruction, reading the branch outcome from the branch-outcome memory, and executing the main loop based on the branch outcome. In some cases, the method, in the main loop, computes the branch outcome of the branch condition again.
