A low power high speed error correction code macro using complementary pass transistor logic circuit
1997
This paper describes the design and implementation of the complementary pass transistor logic (CPL) circuit in a CMOS macro design. The power, speed and noise margin of pass-transistor logic circuits are evaluated and the transistor sizes are optimized for noise margin and circuit performance. This circuit has been successfully implemented in a 64-bit Error Correction Code (ECC) and parity checking macro in the IBM S/390 CMOS processor and significantly improves the power and speed of the ECC macro performance.
