The overall time complexity for both SIMS and MIMD models of their first algorithm was shown to be (8 N<jats:sup>1\/4<\/jats:sup>- 1) electronic moves and 2 OTIS moves. This was further reduced to (7 N<jats:sup>1\/4<\/jats:sup>- 1) electronic moves and 2 OTIS moves in their second algorithm. We present here an improved parallel algorithm for N-point prefix computation on an N-processor OTIS-Mesh, which needs (5.5 N<jats:sup>1\/4<\/jats:sup>+ 3) electronic moves and 2 OTIS moves. Our algorithm is based on the general theme of parallel prefix algorithm proposed in [4] but following the data distribution and local prefix computation similar to that of [1].<\/jats:p>","DOI":"10.1142\/s0129626406002757","type":"journal-article","created":{"date-parts":[[2006,12,20]],"date-time":"2006-12-20T11:24:00Z","timestamp":1166613840000},"page":"429-440","source":"Crossref","is-referenced-by-count":20,"title":["AN IMPROVED PARALLEL PREFIX ALGORITHM ON OTIS-MESH"],"prefix":"10.1142","volume":"16","author":[{"given":"PRASANTA K.","family":"JANA","sequence":"first","affiliation":[{"name":"Department of Computer Science and Engineering, Indian School of Mines, Dhanbad - 826 004, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"BHABANI P.","family":"SINHA","sequence":"additional","affiliation":[{"name":"Advanced Computing and Microelectronics Unit, Indian Statistical Institute, 203 B.T.
