• Asymmetric channel
• Berger codes
• bus-invert
• self-checking design
• unidirectional error detection

Berger-invert code is a coding scheme proposed recently to protect communication channels against all asymmetric errors and to decrease power consumption. This brief proposes a modified encoding scheme of Berger-invert codes and a new design of encoding/decoding circuitry (a codec). Implementation results prove that the new approach reduces the codec area and power consumption, respectively, by up to 30% and 48% for a 32-bit bus and decreases the error rate by up to about 35% for a 6-bit bus.
