Abstract
A system 600 is provided having a line driver 202 for transmitting signals across a line 201 from a first processing circuit 601 to a second processing circuit 602. Line driver 202 receives an input signal from processing circuit 601 having a first voltage swing between a first high voltage level and a first low voltage level. Line driver 202 reduces power dissipation in line 201 by transmitting an output signal on line 201 having a second voltage swing between a second low voltage level greater than the first low voltage level and a second high voltage level less than the first high voltage level. System 600 also contains comparator 610 which receives the signal having the reduced second voltage swing and compares the received signal to a reference voltage. The output of comparator 610 restores the received signal to the full voltage swing of the input signal received by line driver 202 and transfers the restored signal to processing circuit 602.
