摘要:
A register file is provided. The register file includes a plurality of registers configured to form at least one register cluster, each of the registers being configured to have a virtual index defined for each cluster and a physical index defined for each register, and an index converting unit configured to convert the virtual index to the physical index.
摘要:
A debugging apparatus and method are provided. The debugging apparatus may include a breakpoint setting unit configured to store a first instruction corresponding to a breakpoint in a table, stop a program currently being executed, and insert a breakpoint instruction including current location information of the first instruction into the breakpoint; and an instruction execution unit configured to selectively execute one of the breakpoint instruction and the first instruction according to a value of a status bit.
摘要:
A memory managing apparatus and method are provided. The memory managing apparatus may determine, based on a pointer indicator bit, the target memory area on which garbage collection is to be performed, and may perform the garbage collection on the target memory area. The memory managing apparatus may generate the pointer indicator bit and store the generated pointer indicator bit in a pointer field.
摘要:
An interrupt handling technology and a reconfigurable processor are provided. The reconfigurable processor includes a plurality of processing elements, and some of the processing elements are designated for interrupt handling. When an interrupt request occurs while the reconfigurable processor is executing a loop operation, the designated processing elements may process the interrupt request. The interrupt handling technology allows the interrupt request and the loop operation to be processed in parallel.
摘要:
A technology for reducing pipeline a control hazard is provided. A conditional branch is processed through a conditional branch prediction, and a predetermined conditional branch prediction, which is determined as incorrect, may be modified through a following test for the conditional branch prediction, thereby reducing the pipeline control hazard quickly without additional hardware.
摘要:
Provided is a reconfigurable processor that may process a first type of operation in first mode using a first group of functional units, and process a second type of operation in second mode using a second group of functional units. The reconfigurable processor may selectively supply power to either the first group or the second group, in response to a mode-switch signal or a mode-switch instruction.
摘要:
An instruction compressing apparatus and method for a parallel processing computer such as a very long instruction word (VLIW) computer, are provided. The instruction compressing apparatus includes a bundle code generating unit, an instruction compressing unit, and an instruction converting unit. The bundle code generating unit may generate a bundle code in response to an input of instructions to be compressed. The bundle code may indicate whether a current instruction group is terminated, and also whether an instruction group following the current instruction group is a no-operation (NOP) instruction group. The instruction compressing unit may remove a NOP instruction and/or a NOP instruction group from the input instructions according to the generated bundle code. The instruction converting unit may include the generated bundle code in the remaining instructions which have not been removed by the instruction compressing unit.
摘要:
An apparatus and method for dynamically determining the execution mode of a reconfigurable array are provided. Performance information of a loop may be obtained before and/or during the execution of the loop. The performance information may be used to determine whether to operate the apparatus in a very long instruction word (VLIW) mode or in a coarse grained array (CGA) mode.
摘要:
An interrupt support determining apparatus and method for an equal-model processor, and a processor including the interrupt support determining apparatus are provided. The interrupt support determining apparatus determines whether an instruction input to a processor decoder is a multiple latency instruction, compares a current latency of the instruction with a remaining latency if the instruction is a multiple latency instruction, and updates the current latency to the remaining latency if the current latency is greater than the remaining latency.
摘要:
Provided are a computing apparatus based on a reconfigurable architecture and a memory dependence correction method thereof. In one general aspect, a computing apparatus has a reconfigurable architecture. The computing apparatus may include: a reconfiguration unit having processing elements configured to reconfigure data paths between one or more of the processing elements; a compiler configured to analyze instructions to generate reconfiguration information for reconfiguring one or more of the reconfigurable data paths; a configuration memory configured to store the reconfiguration information; and a processor configured to execute the instructions through the reconfiguration unit, and to correct at least one memory dependency among the processing elements.
