Abstract: Systems and methods for efficient replicated block arrays are disclosed. In some embodiments, a computing system can include a plurality of functional blocks, wherein each of the plurality of functional blocks is an instance of a computing circuitry block, and a globals block having a same footprint as an individual one of the functional blocks, the globals block comprising circuitry that is different than the functional block, wherein the plurality of functional blocks and the globals block are included in an array.

Abstract: Systems, apparatuses, and methods for implementing a decoupled crossbar for a stream processor are disclosed. In one embodiment, a system includes at least a multi-lane execution pipeline, a vector register file, and a crossbar. The system is configured to determine if a given instruction in an instruction stream requires a permutation on data operands retrieved from the vector register file. The system conveys the data operands to the multi-lane execution pipeline on a first path which includes the crossbar responsive to determining the given instruction requires a permutation on the data operands. The crossbar then performs the necessary permutation to route the data operands to the proper processing lanes. Otherwise, the system conveys the data operands to the multi-lane execution pipeline on a second path which bypasses the crossbar responsive to determining the given instruction does not require a permutation on the input operands.
