Patent number: 10983800Abstract: A processor core having multiple parallel instruction execution slices and coupled to multiple dispatch queues provides flexible and efficient use of internal resources. The configuration of the execution slices is selectable so that capabilities of the processor core can be adjusted according to execution requirements for the instruction streams. A plurality of load-store slices coupled to the execution slices provides access to a plurality of cache slices that partition the lowest level of cache memory among the load-store slices.Type: GrantFiled: June 6, 2018Date of Patent: April 20, 2021Assignee: International Business Machines CorporationInventors: Lee Evan Eisen, Hung Qui Le, Jentje Leenstra, Jose Eduardo Moreira, Bruce Joseph Ronchetti, Brian William Thompto, Albert James Van Norstrand, Jr.

Patent number: 10157064Abstract: A method of managing instruction execution for multiple instruction streams using a processor core having multiple parallel instruction execution slices. An event is detected indicating that either resource requirement or resource availability for a subsequent instruction of an instruction stream will not be met by the instruction execution slice currently executing the instruction stream. In response to detecting the event, dispatch of at least a portion of the subsequent instruction is made to another instruction execution slice. The event may be a compiler-inserted directive, may be an event detected by logic in the processor core, or may be determined by a thread sequencer. The instruction execution slices may be dynamically reconfigured as between single-instruction-multiple-data (SIMD) instruction execution, ordinary instruction execution, wide instruction execution.Type: GrantFiled: February 27, 2017Date of Patent: December 18, 2018Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Lee Evan Eisen, Hung Qui Le, Jentje Leenstra, Jose Eduardo Moreira, Bruce Joseph Ronchetti, Brian William Thompto, Albert James Van Norstrand, Jr.

Patent number: 10083039Abstract: A processor core having multiple parallel instruction execution slices and coupled to multiple dispatch queues by a dispatch routing network provides flexible and efficient use of internal resources. The configuration of the execution slices is selectable so that capabilities of the processor core can be adjusted according to execution requirements for the instruction streams. Two or more execution slices can be combined as super-slices to handle wider data, wider operands and/or vector operations, according to one or more mode control signal that also serves as a configuration control signal. The mode control signal is also used to partition clusters of the execution slices within the processor core according to whether single-threaded or multi-threaded operation is selected, and additionally according to a number of hardware threads that are active.Type: GrantFiled: January 30, 2018Date of Patent: September 25, 2018Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Lee Evan Eisen, Hung Qui Le, Jentje Leenstra, Jose Eduardo Moreira, Bruce Joseph Ronchetti, Brian William Thompto, Albert James Van Norstrand, Jr.

Patent number: 9690585Abstract: A method of operation of a processor core having multiple parallel instruction execution slices and coupled to multiple dispatch queues coupled by a dispatch routing network provides flexible and efficient use of internal resources. The dispatch routing network is controlled to dynamically vary the relationship between the slices and instruction streams according to execution requirements for the instruction streams and the availability of resources in the instruction execution slices. The instruction execution slices may be dynamically reconfigured as between single-instruction-multiple-data (SIMD) instruction execution and ordinary instruction execution on a per-instruction basis. Instructions having an operand width greater than the width of a single instruction execution slice may be processed by multiple instruction execution slices configured to act in concert for the particular instructions.Type: GrantFiled: June 10, 2014Date of Patent: June 27, 2017Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Lee Evan Eisen, Hung Qui Le, Jentje Leenstra, Jose Eduardo Moreira, Bruce Joseph Ronchetti, Brian William Thompto, Albert James Van Norstrand, Jr.

Patent number: 8271765Abstract: The illustrative embodiments described herein provide a computer-implemented method, apparatus, and a system for managing instructions. A load/store unit receives a first instruction at a port. The load/store unit rejects the first instruction in response to determining that the first instruction has a first reject condition. Then, the instruction sequencing unit activates a first bit in response to the load/store unit rejection the first instruction. The instruction sequencing unit blocks the first instruction from reissue while the first bit is activated. The processor unit determines a class of rejection of the first instruction. The instruction sequencing unit starts a timer. The length of the timer is based on the class of rejection of the first instruction. The instruction sequencing unit resets the first bit in response to the timer expiring. The instruction sequencing unit allows the first instruction to become eligible for reissue in response to resetting the first bit.Type: GrantFiled: April 8, 2009Date of Patent: September 18, 2012Assignee: International Business Machines CorporationInventors: Pradip Bose, Alper Buyuktosunoglu, Michael Stephen Floyd, Dung Quoc Nguyen, Bruce Joseph Ronchetti
