US Classification:

712 22

Abstract:

Systems, methods and articles of manufacture are disclosed for transposing array data on a SIMD multi-core processor architecture. A matrix in a SIMD format may be received. The matrix may comprise a SIMD conversion of a matrix M in a conventional data format. A mapping may be defined from each element of the matrix to an element of a SIMD conversion of a transpose of matrix M. A SIMD-transposed matrix T may be generated based on matrix M and the defined mapping. A row-wise algorithm may be applied to T, without modification, to operate on columns of matrix M.

Abstract:

A system for protecting an electronic device from cosmic rays includes a frame in which the circuit is disposed, a cosmic ray detection circuit and a protection circuit. The cosmic ray detection circuit is supported by the frame and is spaced apart from the circuit. The cosmic ray detection circuit is configured to assert an incoming cosmic ray signal when a cosmic ray interacts with the cosmic ray detection device. The protection circuit is coupled to the incoming cosmic ray signal and is configured to cause the electronic device to enter a protected state when the cosmic ray signal is asserted.
