Integrated circuits with novel handshake logic

A routing structure, comprising:

• a C-element having a control output;
• a plurality of logic gates, each logic gate having a first input coupled to the control output of the C-element, a second input, and an output;
• N storage elements, each storage element having a plurality of control inputs coupled to the outputs of the plurality of logic gates, each storage element being further coupled to receive M input data signals and to store a selected one of the M input data signals, N being a positive integer, M being an integer greater than one;
• an M-input ready multiplexer coupled to receive M ready signals and to drive a ready input of the C-element;
• and
• an M-output acknowledge demultiplexer coupled to receive an acknowledge signal from the control output of the C-element and to provide M acknowledge output signals.

An integrated circuit (IC), comprising:

• a plurality of logic blocks;
• and
• a plurality of routing structures programmably interconnecting the logic blocks one to another,
• wherein each of the routing structures comprises:
• a ready multiplexer;
• an acknowledge demultiplexer;
• a C-element coupled to the ready multiplexer and the acknowledge demultiplexer, the C-element having a control output;
• a logic gate having a first input coupled to the control output of the C-element, a second input, and an output;
• and
• a first storage element, comprising:
• a first data multiplexer having M data inputs coupled to inputs of the first storage element, a select input coupled to the output of the logic gate, and a data output, M being an integer greater than one;
• and
• a first latch having a data input coupled to the data output of the first data multiplexer and an output coupled to an output of the first storage element.
