Abstract

Processing circuiter 100 is provided having a passive data transfer capability. Processing circuitry 100 includes a bus 116, a first subsystem 105 coupled to bus 116 through first passive transfer logic 120a, and a second subsystem 108 coupled to bus 116 through second passive transfer logic 120b. Processing circuitry 100 further includes control circuitry 101/103 coupled to bus 116 for initiating a passive data transfer between first and second subsystems 105 and 108, first and second passive transfer logic 120a and 120b there after controlling exchange of data between the first and second subsystems 105 and 108 independent of the control circuitry 101/103.
