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.

Abstract: An arithmetic logic unit (ALU) pipeline of a processing unit collapses execution bubbles in response to a stall at a stage of the ALU pipeline. An execution bubble occurs at the pipeline in response to an invalid instruction being placed in the pipeline for execution. The invalid instruction thus consumes an available “slot” in the pipeline, and proceeds through the pipeline until a stall in a subsequent stage (that is, a stage after the stage executing the invalid instruction) is detected. In response to detecting the stall, the ALU continues to execute instructions that are behind the invalid instruction in the pipeline, thereby collapsing the execution bubble and conserving resources of the ALU.in response to a stall at a stage of the ALU pipeline.

Abstract: Three-dimensional electrical source imaging of electrical activity in a biological system (e.g., brain or heart) may involve sensor array recording, at multiple locations, of signals (e.g. electrical or magnetic signals) of electrical activity. An initial estimate of an underlying source is obtained. Edge sparsity is imposed on the estimated electrical activity to eliminate background activity and create clear edges between an active source and background activity. The initial estimate is iteratively reweighted and a series of subsequent optimization problems launched to converge to a more accurate estimation of the underlying source. Images depicting a spatial distribution of a source are generated based on the iteratively reweighted edge sparsity, and the time-course of activity for estimated sources generated. Iterative reweighting penalizes locations with smaller source amplitude based on solutions obtained in previous iterations, and continues until a desirable solution is obtained with clear edges.
