Design of a fine-grain reconfigurable VLSI based on logic-in-control architecture

A multiple-valued reconfigurable VLSI based on logic-in-control architecture is proposed to make interconnections between arithmetic/logic circuits and control circuits simple. Hybrid programming scheme based on wired programming and dynamic data-path control programming is introduced to achieve high utilization ratio of hardware resources. In logic-in-control architecture, the control circuit constructed by using multiple logic blocks can be provided near the arithmetic/logic circuit, which leads to small propagation delay of control signals. To reduce the complexity of interconnections between logic blocks in the control circuit, only one state in a state transition diagram is allocated to one logic block. Moreover, a logic block useful for implementing both of the arithmetic/logic circuit and the control circuit is designed by using a multiple-valued current-mode logic circuit.
