摘要： The present invention discloses a method and apparatus for encoding an instruction in an instruction set which uses a prefix code to qualify an existing opcode of an existing instruction. An opcode and an escape code are selected. The escape code is selected such that it is different from the prefix code and the existing opcode. The opcode, the escape code, and the prefix code are combined to generate an instruction code which uniquely represents the operation performed by the instruction.

摘要： The present invention discloses a method and apparatus for saving and restoring registers. A single instruction is decoded. The single instruction moves contents of a plurality of registers associated with a functional unit in a processor to a memory; the processor operates under a plurality of operational modes and operand sizes. The single instruction arranges the contents in the memory according to a predetermined format into a plurality of groups, each group is aligned at an address boundary which corresponds to a multiple of 2N bytes. The predetermined format is constant for the plurality of operational modes and operand sizes. The single instruction retains the contents of the plurality of registers after moving.

摘要： Method, apparatus, and program means for shuffling data. The method of one embodiment comprises receiving a first operand having a set of L data elements and a second operand having a set of L control elements. For each control element, data from a first operand data element designated by the individual control element is shuffled to an associated resultant data element position if its flush to zero field is not set and a zero is placed into the associated resultant data element position if its flush to zero field is not set.

摘要： A method for an extended precision integer divide algorithm includes separating an L-bit integer dividend into two equal width integer format portions, a first portion including lower M bits of the integer dividend and a second portion including upper M bits of the integer dividend, where M is equal to ½ L. An N-bit wide integer divisor is converted from an integer format into a floating point format divisor. The first integer portion is converted into a floating point format and divided by the floating point format divisor to obtain a first floating point quotient, which is converted into a first integer format quotient. The second integer portion is converted into a floating point format and divided by the floating point format divisor to obtain a second floating point quotient which is also converted to a second integer format quotient. Then first and second integer format quotients are summed together to generate a third integer format quotient.

摘要： A method and apparatus for including in a processor, instructions for performing multiply-intra-add operations on packed data is described. In one embodiment, a processor is coupled to a memory. The memory has stored therein a first and a second packed data. The processor performs operations on data elements in the first packed data and the second packed data to generate a plurality of data elements in a third packed data in response to receiving an instruction. At least two of the plurality of data elements in the third packed data store the result of multiply-intra-add operations.

摘要： Method, apparatus, and program means for rearranging data between multiple registers. The method of one embodiment comprises shuffling first set of packed data from a first source based on a first set of masks to produce a first set of shuffled data. The first set of masks is to include a first plurality of control entries to set designated data element positions in the first set of shuffled data to zero. A second packed data from a second source is shuffled based on a second set of masks to produce a second set of shuffled data. The second set of masks includes a second plurality of control entries to set to zero data element positions in the second set of shuffled data opposite to said designated data element positions in the first set of shuffled data. The first set of shuffled data and said second set of shuffled data are merged together to form a packed data resultant.
