20080282061 | Array Type Operation Device - An array calculation device that includes a processor array composed of a plurality of processor elements having been assigned with orders, acquires an instruction in each cycle, generates, in each cycle, operation control information for controlling an operation of a processor element of a first order, and then generates an instruction to the processor element of the first order in accordance with the operation control information and the acquired instruction, and also generates, in each cycle, operation control information for controlling an operation of each processor element of a next order and onwards, in accordance with operation control information generated for controlling an operation of a processor element of an immediately preceding order, and then generates an instruction to each processor element of the next order and onwards, in accordance with the operation control information generated and the acquired instruction. | 11-13-2008 |
20090037779 | EXTERNAL DEVICE ACCESS APPARATUS - In response to a write request from a master to write to an external device, a control unit holds a write address and write data from the master in a write address holding unit and in a write data holding unit, respectively, outputs a reception signal to the master, and writes the write data to the external device specified by the write address. When the master holds the read address in the read address holding unit, the control unit reads data from the external device specified by the read address, and holds the read data in the read data holding unit. | 02-05-2009 |
20090037916 | PROCESSOR - The present invention provides a processor that cyclically executes a plurality of threads in accordance with an execution time allocated to each of the threads, comprising a reconfigurable integrated circuit. The processor stores circuit configuration information sets respectively corresponding to the plurality of threads, reconfigures a part of the integrated circuit based on the circuit configuration information sets, and sequentially executes each thread using the integrated circuit that has been reconfigured based on one of the configuration information sets that corresponds to the thread. While executing a given thread, the processor selects a thread to be executed next, and reconfigures a part of the integrated circuit where is not currently used for execution of the given thread, based on a circuit configuration information set corresponding to the selected thread. | 02-05-2009 |

20110113220 | MULTIPROCESSOR - Provided is a multiprocessor capable of executing a plurality of threads without decreasing execution efficiency. | 05-12-2011 |
20120060017 | PROCESSOR - A processor including L computing units, L being an integer of 2 or greater, the processor comprising: an instruction buffer including M×Z instruction storage areas each storing one instruction, M instruction streams being input in a state of being distinguished from each other, each of the M instruction streams including Z instructions, M and Z each being an integer of 2 or greater, M×Z being equal to or greater than L; an order information holding unit holding order information that indicates an order of the M×Z instruction storage areas; an extraction unit operable to extract instructions from the M×Z instruction storage areas; and a control unit operable to cause the extraction unit to extract L instructions in executable state from the M×Z instruction storage areas in accordance with the order indicated by the order information, and input the instructions into different ones of the L computing units. | 03-08-2012 |
20120167036 | PROGRAM GENERATION DEVICE, PROGRAM PRODUCTION METHOD, AND PROGRAM - A program generation apparatus references a source program including a loop for executing a block N times (N≧2) and having such dependence that a variable defined in a statement in the block pertaining to i | 06-28-2012 |
20120167114 | PROCESSOR - Provide is a processor that can maintain a dependency relationship between a plurality of instructions and one read instruction. The processor comprises: a setting unit configured to set, when an instruction that exists at a location ensuring that writing into a memory area has been completed is executed, usage information indicating whether writing into the memory area has been completed such that the usage information indicates that writing into a memory area during execution of one thread has been completed; and a control unit configured to (i) perform execution of a read instruction to read data stored in the memory area when the usage information indicates that writing into the memory area during execution of the one thread has been completed, and (ii) suppress execution of the read instruction when the usage information indicates that writing into the memory area during execution of the one thread has not been completed. | 06-28-2012 |

20140136821 | MULTIPROCESSOR SYSTEM - To provide a multi-processor system that efficiently debugs operations of one processor and operations of another processor. The multiprocessor system has a first processor and a second processor that executes processing by receiving notification from the first processor. The first processor: sequentially specifies instructions to be executed from an instruction queue; sends a notification based on a processing request instruction to the second processor when an instruction that is specified is the processing request instruction; executes the instruction that is specified when the instruction that is specified is not the processing request instruction; and determines whether or not a debug mode is set. When the first processor determines that the debug mode is set, the first processor stops specifying instructions after specifying the processing request instruction, and, after sending the notification, resumes specifying instructions after detecting that the second processor has completed processing corresponding to the notification. | 05-15-2014 |
