Abstract
This present invention provides a fast data transfer for a concurrent transfer of multiple ROI areas between an internal memory array and a single memory where each PE can specify the parameter set for the area to be transferred independently from the other PE. For example, for a read transfer, the requests are generated in a way that first the first element of each ROI area is requested from the single memory for each PE before the following elements of each ROI area are requested. After the first element from each ROI area has been received from the single memory in a control processor and has been transferred from the control processor over a bus system to the internal memory array, all elements are in parallel stored to the internal memory array. Then, the second element of each ROI area is requested from the single memory for each PE. The transfer finishes after all elements of each ROI area are transferred to their assigned PEs.
