Abstract: In a data processing arrangement that includes multiple processing circuits, a group of storage elements provides temporary storage of data intended for the processing circuits. An element selection circuit enables a single storage element to be selected from a plurality of storage elements in order to supply the content of the selected storage element to an input of a processing circuit. A group selection circuit enables a group of storage elements to be selected from a plurality of separate groups of storage elements in order to supply the contents of all the storage elements forming part of the selected group to an input of another processing circuit. Such an arrangement affords a flexible and efficient use of all the storage elements. As a result, a comparatively small number of storage elements are necessary, which leads to cost reduction. The relevant arrangement may be employed in, for example, a digital signal processor capable of (finite impulse response) FIR filtering.

Abstract: A data processing arrangement comprises a plurality of processing circuits [PRC]. A group of storage elements [SE] serves for the temporary storage of data intended for the processing circuits [PRC]. An element selection circuit [SELN] enables a single storage element [SE(i, 1)] to be selected from a plurality of storage elements [SE(1,1), SE(1,2), . . . SE(N,1), SE(N,2)] in order to supply the content of the selected storage element [SE(i,1)] to an input of a processing circuit [PRC1]. A group selection circuit [SELW] enables a group of storage elements [GRP(j)] to be selected from a plurality of separate groups of storage elements [GRP(1)-GRP(N)] in order to supply the contents of all the storage elements [SE] forming part of the selected group [GRP(j)] to an input of another processing circuit [PRC2].
