Abstract: Systems and methods for supporting a plurality of load and store accesses of a cache are disclosed. Responsive to a request of a plurality of requests to access a block of a plurality of blocks of a load cache, the block of the load cache and a logically and physically paired block of a store coalescing cache are accessed in parallel. The data that is accessed from the block of the load cache is overwritten by the data that is accessed from the block of the store coalescing cache by merging on a per byte basis. Access is provided to the merged data.

Abstract: A matrix of execution blocks form a set of rows and columns. The rows support parallel execution of instructions and the columns support execution of dependent instructions. The matrix of execution blocks process a single block of instructions specifying parallel and dependent instructions.
