    • A SIMD processor architecture (2) for processing a stream of data vectors is provided, the architecture comprising a processor array (4) comprising a plurality of processors (PE(0), . . . , (PE(N)), each processor ((PE(0), . . . PE(N)) being adapted to process a data element in each vector, the operation of the processor array (4) being controlled by a local clock signal having a first frequency; a control processor (16) adapted to control the operation of the SIMD processor architecture (2) and generate signals to synchronise the operation of the processor array (4) with the stream of data vectors, the operation of the control processor (16) being controlled by a local clock signal having a second frequency; and power management means (30) for adjusting the frequencies of the local clock signals in response to the synchronisation signals generated by the control processor (16), thereby minimising the power consumption of the SIMD processor architecture (2).
    • 提供了一种用于处理数据向量流的SIMD处理器架构(2),该架构包括包括多个处理器(PE(0),...,(PE(N))的处理器阵列(4) ((PE(0),...,PE(N))适于处理每个向量中的数据元素,处理器阵列(4)的操作由具有第一频率的本地时钟信号控制;控制处理器 (16)适于控制SIMD处理器架构(2)的操作并产生信号以使处理器阵列(4)的操作与数据向量流同步,控制处理器(16)的操作由 具有第二频率的本地时钟信号;以及用于响应于由控制处理器(16)产生的同步信号调整本地时钟信号的频率的功率管理装置(30),由此最小化SIMD处理器架构的功耗 2)。
