Asynchronous circuit design using Handshake Solutions

A dynamically reconfigurable asynchronous processor

“…On the other hand, two-phase signalling has the potential to be faster and more power efficient than four-phase because it uses each transition in a handshake. However, this is not the case with current tools such as Balsa [50] and TiDE [48] which favour four-phase signalling. As a result, four-phase signalling was the choice in the operational cell design.…”

“…Petri nets [33] There are many tool based compiler transformation methods. These include CAST [17] based on Martin's translation process [47], TiDE (Handshake Solutions) [48]…”

“…TiDE uses a CSP-like programming language called Haste. [48] TiDE works as follows ( Figure C.1 // The simplest way for now to do the submapling, is for output 0 of even // values (this value will not be stored anyway), and for the odd x's to // find the average over 3 pixels (previous, current and future). write_sink_w_sync(0, y0_rel, 1, 1, 1); //YUY2 write_sink_w_sync(1, y0_im, 1, 1, 1); //YUY2 write_sink_w_sync(2, y1_rel, 1, 1, 1); //YUY2 write_sink_w_sync (3, y1_im, 1, 1, 1); //YUY2 // output_16_bit(output_pixel, 1); } return 0; }…”
