Conditional execution with multiple destination stores

A computer system for conditionally performing a SIMD operation using operands from at least one source store and causing a predetermined number of result objects to be held in a combination of different ones of a plurality of a destination stores, the computer system comprising:

• a plurality of stores;
• decode circuitry for receiving and decoding an instruction and operable to determine at least one source store, a plurality of destination stores, and at least one control store, wherein each said source and destination store is capable of holding one or a plurality of source objects and result objects, respectively, each source object defining a SIMD lane, and wherein said at least one control store comprises a plurality of pre-set indicators for controlling per SIMD lane conditional execution;
• a plurality of operators operable to perform the operation defined in the instruction on each said SIMD lane;
• control circuitry for controlling per SIMD lane conditional execution of the operation, wherein the control circuitry comprises said at least one control store and said plurality of pre-set indicators are operable to indicate for each of a plurality of result lanes whether or not a result should be generated on that result lane, each said pre-set indicator being operable to control a plurality of result lanes;
• and
• a plurality of destination stores connected to receive a predetermined number of result objects, wherein the predetermined number of result objects are held by a combination of different ones of the plurality of destination stores.

A method for conditionally performing a SIMD operation using operands from at least one source store and causing result objects to be sent to different ones of a plurality of destination stores, the method comprising:

• receiving and decoding an instruction defining an operation, the instruction indicating at least one source store, a plurality of destination stores, and at least one control store, each said source and destination store being capable of holding one or a plurality of source and result objects, respectively, each source object defining a SIMD lane;
• controlling per SIMD lane conditional execution of the operation, wherein respective pre-set indicators of said at least one control store are operable to control a plurality of corresponding result lanes;
• and
• sending objects resulting from the operation on respective predetermined lanes to said plurality of destination stores.

A method for conditionally performing multiple data processing operations and multiple load/store operations contemporaneously, the method comprising:

• providing first and second SIMD execution channels, each being capable of processing a data processing operation and a load/store operation contemporaneously;
• receiving and decoding a first portion of an instruction responsive to parameters defining first and second data processing operations;
• receiving and decoding a second portion of an instruction responsive to parameters defining first and second load/store operations;
• and
• conditionally performing said first and second data processing operations and said first and second load/store operations contemporaneously on a per SIMD lane basis, wherein said first data processing operation and said first load/store operation are contemporaneously performed by said first SIMD execution channel and said second data processing operation and said second load/store operation are contemporaneously performed by said second SIMD execution channel.
