Abstract: A processor of an aspect includes a decode unit to decode a matrix multiplication instruction. The matrix multiplication instruction is to indicate a first memory location of a first source matrix, is to indicate a second memory location of a second source matrix, and is to indicate a third memory location where a result matrix is to be stored. The processor also includes an execution unit coupled with the decode unit. The execution unit, in response to the matrix multiplication instruction, is to multiply a portion of the first and second source matrices prior to an interruption, and store a completion progress indicator in response to the interruption. The completion progress indicator to indicate an amount of progress in multiplying the first and second source matrices, and storing corresponding result data to the third memory location, that is to have been completed prior to the interruption.

Abstract: In one embodiment, a heterogeneous multicore processor is described that is optimized to execute multi-stage computer vision algorithms such as cascade classifier workloads. In such embodiment the heterogeneous processor includes at least one SIMD core, such as a vector processor core, coupled with one or more scalar cores. In one embodiment the heterogeneous multiprocessor executes multi-stage compute operations, where the SIMD core computes a first set of stages and the one or more scalar cores compute the second set of stages. In one embodiment, a process for designing a heterogeneous multicore processor is disclosed which optimizes the ratio of scalar to SIMD cores based on execution time of the multi-stage compute operation in relation to processor die area consumed by a processor configuration having the ratio.

Abstract: In an embodiment, a method is provided. The method includes managing user-level threads on a first instruction sequencer in response to executing user-level instructions on a second instruction sequencer that is under control of an application level program. A first user-level thread is run on the second instruction sequencer and contains one or more user level instructions. A first user level instruction has at least 1) a field that makes reference to one or more instruction sequencers or 2) implicitly references with a pointer to code that specifically addresses one or more instruction sequencers when the code is executed.

Abstract: Embodiments of an invention a processor architecture are disclosed. In an embodiment, a processor includes a decoder, an execution unit, a coherent cache, and an interconnect. The decoder is to decode an instruction to zero a cache line. The execution unit is to issue a write command to initiate a cache line sized write of zeros. The coherent cache is to receive the write command, to determine whether there is a hit in the coherent cache and whether a cache coherency protocol state of the hit cache line is a modified state or an exclusive state, to configure a cache line to indicate all zeros, and to issue the write command toward the interconnect. The interconnect is to, responsive to receipt of the write command, issue a snoop to each of a plurality of other coherent caches for which it must be determined if there is a hit.

Abstract: A processor includes a decode unit to decode a packed finite impulse response (FIR) filter instruction that indicates one or more source packed data operands, a plurality of FIR filter coefficients, and a destination storage location. The source operand(s) include a first number of data elements and a second number of additional data elements. The second number is one less than a number of FIR filter taps. An execution unit, in response to the packed FIR filter instruction being decoded, is to store a result packed data operand. The result packed data operand includes the first number of FIR filtered data elements that each is to be based on a combination of products of the plurality of FIR filter coefficients and a different corresponding set of data elements from the one or more source packed data operands, which is equal in number to the number of FIR filter taps.

Abstract: A processor includes a decode unit to decode an instruction that is to indicate a first source packed data operand that is to include at least four data elements, to indicate a second source packed data operand that is to include at least four data elements, and to indicate one or more destination storage locations. The execution unit, in response to the instruction, is to store at least one result mask operand in the destination storage location(s). The at least one result mask operand is to include a different mask element for each corresponding data element in one of the first and second source packed data operands in a same relative position. Each mask element is to indicate whether the corresponding data element in said one of the source packed data operands equals any of the data elements in the other of the source packed data operands.

Abstract: Instructions and logic provide SIMD vector packed histogram functionality. Some processor embodiments include first and second registers storing, in each of a plurality of data fields of a register lane portion, corresponding elements of a first and of a second data type, respectively. A decode stage decodes an instruction for SIMD vector packed histograms. One or more execution units, compare each element of the first data type, in the first register lane portion, with a range specified by the instruction. For any elements of the first register portion in said range, corresponding elements of the second data type, from the second register portion, are added into one of a plurality data fields of a destination register lane portion, selected according to the value of its corresponding element of the first data type, to generate packed weighted histograms for each destination register lane portion.
