Low-energy (adiabatic)\nlogic circuits have been proposed to reduce energy consumption of VLSI\nlogic functions. Instead of the conventional dc power supply, these\nlogic circuits use "ac" power supplies (power clocks) that\nallow energy recovery and also serve as timing clocks for the logic....
The synchronization time of the clock arbitration circuit, TS, which represents the minimum time required between the source and destination clocks in order for the signal to be successfully latched at the destination. We assume the arbitration and synchronization circuits developed by Sjogren and Myers...
whereas the CXB board is a board that generates the system clocks (see FIG. 1 at28). Other boards are also listed, such as the SXB boards (switching matrices)(see FIG. 1 at30), the SIOB boards (I/O board interface)(see FIG. 1 at26) and the IO boxes46. In panel104, three tab...
