Abstract: PURPOSE: A method for processing a command through a processing element and a processing apparatus thereof are provided to realize a DISE(Double Issue Single Execution), thereby rapidly processing a branch statement on the processing element. CONSTITUTION: A branch statement includes a first sentence unit which is a set of instructions to successively execute if a condition is satisfied, and a second sentence unit which is a set of instructions to successively execute if the condition is not satisfied. An instruction fetching unit(320) stores a first instruction and a second instruction in separate spaces of instruction buffer at the same time. A condition comparison unit(340) sets up a flag, which commands execution of the first or the second sentences, in a register assigned to a PE(Processing Element) according to a calculation result of the PE and a comparison result of the condition. A decoder(350) decodes the first or the second instructions saved in the instruction buffer according to the flag.

Abstract translation: 目的：提供一种通过处理元件处理命令的方法及其处理装置，以实现DISE（双问题单执行），从而快速处理处理元件上的分支语句。 构成：分支语句包括第一句子单元，其是如果条件被满足则连续执行的一组指令，以及第二句子单元，其是如果条件不满足则连续执行的一组指令。 指令取出单元（320）同时在指令缓冲器的分离空间中存储第一指令和第二指令。 条件比较单元（340）根据PE的计算结果和条件的比较结果，在分配给PE（处理单元）的寄存器中设置命令执行第一或第二句子的标志。 解码器（350）根据标志解码存储在指令缓冲器中的第一或第二指令。

Abstract: PURPOSE: A processing device, a PE control device, and a method thereof are provided to support predication execution in a SIMD(Single Command Multiple Data) machine by the state of PE is changed according to the conditional information of sleep command. CONSTITUTION: A PE(Processing Element)(200) performs calculation according to control signals. A PE controller(210) transmits control signals outputted based on external command to the PE. When the command is a sleep command including condition information and a sleep cycle value, the PE controller compares the condition information of the sleep command with the former calculation result performed by the PE. When the calculation result is matched in the condition of the condition information of the sleep command, the PE controller blocks the electrical transmission of the control signal according to the command for the cycle of the sleep cycle value.

Abstract translation: 目的：提供一种处理装置，PE控制装置及其方法，以根据睡眠命令的条件信息来改变SIMD（Single Command Multiple Data，单命令多数据）机器中的状态的预测执行。 构成：PE（处理元件）（200）根据控制信号进行计算。 PE控制器（210）将对外部命令输出的控制信号发送给PE。 当命令是包括条件信息和睡眠周期值的休眠命令时，PE控制器将休眠命令的条件信息与PE执行的前一计算结果进行比较。 当在睡眠命令的条件信息的条件下计算结果匹配时，PE控制器根据睡眠周期值周期的命令来阻止控制信号的电传输。
