and a low power encoding scheme were evaluated. The combination the PBI * and

parity (PAR) codes was found to reduce both self and coupling transitions better

than other combinations.

7.6 SUMMARY

In this chapter, we described encoding techniques for on-chip communication

architectures that are used to transform the data to be transmitted. Encoding is a

commonly used and benefi cial technique which can lead to reduction in switch-

ing power, propagation delay, crosstalk noise (both inductive and capacitive), and

transmission errors. While several encoding techniques have been proposed that
