Abstract: An apparatus and method for efficient matrix alignment in a systolic array.

Abstract: In one embodiment, logic is provided to receive and execute a mask move instruction to transfer a vector data element including a plurality of packed data elements from a source location to a destination location, subject to mask information for the instruction, such that only portions of the plurality of packed data elements are transferred to the destination location. Other embodiments are described and claimed.

Abstract: In one embodiment, the present invention includes logic to receive a permute instruction, first and second source operands, and control values, and to perform a permute operation based on an operation between at least two of the control values so that selected portions of the first and second source operands or a predetermined value can be stored into elements of a destination. Multiple permute instructions may be combined to perform efficient table lookups. Other embodiments are described and claimed.

Abstract: Methods and apparatus for using micro-op caches in processors are disclosed. A tag match for an instruction pointer retrieves a set of micro-op cache line access tuples having matching tags. The set is stored in a match queue. Line access tuples from the match queue are used to access cache lines in a micro-op cache data array to supply a micro-op queue. On a micro-op cache miss, a macroinstruction translation engine (MITE) decodes macroinstructions to supply the micro-op queue. Instruction pointers are stored in a miss queue for fetching macroinstructions from the MITE. The MITE may be disabled to conserve power when the miss queue is empty-likewise for the micro-op cache data array when the match queue is empty. Synchronization flags in the last micro-op from the micro-op cache on a subsequent micro-op cache miss indicate where micro-ops from the MITE merge with micro-ops from the micro-op cache.

Abstract: A memory cache bank prediction unit is provided for use in a processor having a plurality of memory cache banks. The memory cache bank prediction unit has an input port that receives an instruction. The memory cache bank prediction unit also has an evaluation unit, coupled to the input port, that predicts which of the plurality of memory cache banks is associated with the instruction.

Abstract: According to an embodiment of the present invention, a microprocessor includes an expanded logical register set that can be accessed by instructions including legacy opcodes and remapped addressing mode information. The known IA-32 instruction set is limited to accessing eight logical general integer registers. An IA-32 instruction can specify which of the eight logical general integer registers are to be accessed via 3-bit register identifier fields of the addressing mode information of the instruction. Each 3-bit register identifier can specify any of the eight logical general integer registers. An expanded logical register set (e.g., sixteen logical registers, thirty-two logical registers, sixty-four logical registers, etc.) can be accessed by remapping the addressing mode information to include at least four-bit register identifiers without defining new opcodes or defining additional instruction prefixes.
