Abstract:
1. A method for synchronizing a multiple-circuit system, said system including a plurality of circuits, each circuit having a synchronous input port for receiving input data and a local clock signal associated with the input data, a signal processing portion, and at least one output port for outputting processed data, said method comprising: selecting a master circuit from said plurality of circuits, the remaining circuits including at least one slave circuit; generating at least one control signal at said master circuit using the local clock signal of said master circuit; outputting said at least one control signal from said master circuit; forwarding said at least one control signal to said at least one slave circuit; looping back said at least one control signal to said master circuit; operating said at least one slave circuit using said forwarded control signal; and operating said master circuit using said looped-back control signal, timings of said operating said at least one slave circuit and said operating said master circuit being aligned within one clock cycle of said local clock signal.
