Single interconnect, multi-bit interface

摘要

Disclosed is transmission of a signal over a single interconnect between functional blocks of the IC. A scaled or encoded signal responsive to a first digital signal is generated by summing currents responsive to the first control signal. The summed currents, which may be the sum of one or more currents, is the scaled signal. The encoded signal is transmitted over a single interconnect. This transmission occurs in one clock period in contrast to the at least two clock periods required to serially transmit data. The encoded signal is then used to generate a second digital signal. The generation of the second digital signal preferably includes mirroring the current of the encoded signal. The mirrored current is can then generate one or more separate voltages which are used to generate the second digital signal.
