摘要:
The circuit includes a plurality of input lines (10, 12, 14) that are each connected to switching devices (22, 24, 26) that gate a selected one of the input lines to an internal node (34). Individual control signals control the operation of each of the switching devices connected to the input lines. An inverter (51) is included having an input connected to the internal node (34) to provide the multiplexor circuit output signal. This output signal is an inversion of the received input signal. A feedback circuit (40) is provided to provide a voltage level to this internal node to ensure a low output level in the absence of any gated input signal.
摘要:
A processor for performing floating point arithmetic operations includes a circuit that performs a first floating point arithmetic operation on a set of operands in a first cycle and a second floating point arithmetic operation on an operand and a result of the first floating point arithmetic operation during a second cycle. A control circuit is provided for, in a third cycle, transferring a result of the second floating operation to the first floating point circuit for a first floating point operation in a next successive cycle while rounding the result of the second floating point operation.
