Abstract

Area performance of systolic sorters is investigated by introducing the river routing model. Three kinds of systolic sorters; Batcher's bitonic sort, Stone's shuffle sort, and odd-even transposition sort on a mesh-connected array, are discussed. It is pointed out that the area performance of systolic sorters is dominated by wiring space between cells. To remedy the synchronization problem due to the clock skew, a hybrid sorter and a recirculating hybrid sorter are proposed here. It is confirmed that the recirculating hybrid sorter is reconfigurable and suitable for WSI implementation.
