Abstract: Disclosed embodiments relate to systems and methods for performing instructions to transform matrices into a row-interleaved format. In one example, a processor includes fetch and decode circuitry to fetch and decode an instruction having fields to specify an opcode and locations of source and destination matrices, wherein the opcode indicates that the processor is to transform the specified source matrix into the specified destination matrix having the row-interleaved format; and execution circuitry to respond to the decoded instruction by transforming the specified source matrix into the specified RowInt-formatted destination matrix by interleaving J elements of each J-element sub-column of the specified source matrix in either row-major or column-major order into a K-wide submatrix of the specified destination matrix, the K-wide submatrix having K columns and enough rows to hold the J elements.

Abstract: Methods and apparatuses relating to memory corruption detection are described. In one embodiment, a hardware processor includes an execution unit to execute an instruction to request access to a block of a memory through a pointer to the block of the memory, and a memory management unit to allow access to the block of the memory when a memory corruption detection value in the pointer is validated with a memory corruption detection value in the memory for the block, wherein a position of the memory corruption detection value in the pointer is selectable between a first location and a second, different location.
