In this paper, a method combining the loop pipelining technique with data prefetching, called Partition Scheduling with Prefetching (PSP), is proposed. In PSP, the iteration space is first divided into regular partitions. Then a two-part schedule, consisting of the ALU and memory parts, is produced and balanced to produce high throughput. These two parts(More)
Many common iterative or recursive DSP applications can be represented by synchronous data-flow graphs (SDFGs). A great deal of research has been done attempting to optimize such applications through retiming. However, despite its proven effectiveness in transforming single-rate data-flow graphs to equivalent DFGs with smaller clock periods, the use of(More)
Cervical dystonia (CD) is characterized by sustained contractions of the neck musculature, resulting in abnormal head postures. The Cervical Dystonia Severity Scale (CDSS) was developed to provide a reliable measure of treatment response in patients with CD. The CDSS uses a protractor and wall chart to rate the severity of the head's deviation from neutral(More)
Many iterative or recursive applications commonly found in DSP and image processing applications can be represented by data-flow graphs (DFGs). This graph is then used to perform DFG scheduling , where the starting times for executing the application's individual tasks are determined. The minimum length of time required to execute all tasks once is called(More)

This paper addresses the issue of determining the iteration bound for a synchronous data flow graph (SDFG) and determining whether or not a SDFG is live based on some calculations done. The main result of this paper is finding an iteration bound equation that is used to find an integral static schedule for the SDFG, where a node is issued at the beginning(More)
Conditioned medium from human T cell leukemia virus type 2 (HTLV-II)-infected T cells supports the growth and long-term culture of cells derived from acquired immunodeficiency syndrome (AIDS)-associated Kaposi's sarcoma lesions (AIDS-KS cells). A protein of 30 kilodaltons was purified from conditioned medium that supports the growth of AIDS-KS cells. The(More)
