摘要: Look up tables for use in programmable logic devices are modified to facilitate of those provide adders (including subtracters) and various types counters. Each look table is effectively partitioned into smaller when an adder or counter required. One portion the used a sum out signal, while other fast carry signal application next stage counter.
