Abstract :
A new, highly reconfigurable carry-skip adder for media signal processing is presented. The proposed circuit can be partitioned to perform one 64-, two 32-, four 16- and eight 8-bit additions. Partitioning is obtained without increasing the critical path. When the AMS 0.35 μm two-poly three-metal 3.3 V CMOS (CSD) process is used to produce the layout, the worst propagation delay and dissipation obtained is about 6.5 ns and 148 μW/ MHz
