Abstract
A method for storing a k-bit output value for each of a plurality of m-bit input values in a memory having an n-bit word stored at each of 2.sup.n n-bit addresses, wherein m, n and k are positive integers, m>n>k and m-n.gtoreq.k, the method comprising the steps of storing a first k-bit output value corresponding to a first m-bit input value at a first n-bit address in the memory, and storing the 2n-m most significant bits of the first n-bit address at a second n-bit address, the stored 2n-m most significant bits of the first n-bit address occupying the 2n-m most significant bits at the second n-bit address, the first and second n-bit addresses being selected such that the n most significant bits of the first m-bit input value correspond to the n bits making up the second n-bit address and the m-n least significant bits of the first m-bit input value correspond to the m-n least significant bits making up the first n-bit address.
