    Abstract: An apparatus and method are described for multi-bit error correction and detection. For example, one embodiment of a processor comprises: error detection logic to detect one or more errors in data when reading the data from a storage device, the data being read from the storage device with parity codes and error correction codes (ECCs); error correction logic to correct the errors detected by the error detection logic; and a matrix usable by both the error detection logic to detect the one or more errors and the error correction logic to correct the errors, the matrix constructed into N regions, each region having M columns forming a geometric sequence, wherein each successive region is a shifted version of a prior region.

    Abstract: According to one embodiment, a processor includes an instruction decoder to decode a first instruction to gather data elements from memory, the first instruction having a first operand specifying a first storage location and a second operand specifying a first memory address storing a plurality of data elements. The processor further includes an execution unit coupled to the instruction decoder, in response to the first instruction, to read contiguous a first and a second of the data elements from a memory location based on the first memory address indicated by the second operand, and to store the first data element in a first entry of the first storage location and a second data element in a second entry of a second storage location corresponding to the first entry of the first storage location.
