This paper points out that StarFabri is an open sw it hed fabri te hnology good in sw it h ing performan e and exp loitability. StarFabri w ill a elerate the developm ent of signal and information pro essor based on sw it hed fabri te hnology. In this paper, the status quo of sw it hed fabr i te hnology is introdu ed, and StarFabri is resear hed emphati ally, in lu- d ing its spe ifi ation, operational prin iples, te hnology traits, and hardw are sofwt are. A omparison w ith other major sw it hed fabri te hnologies, its appli ation prospe ts, and some suggestions of its option are brought up asw el.l K ey words: sw it hed fabri; StarFabri; memory map; rossbar , 0 , ( Bus), [ 1]
