Abstract

An interleaver or deinterleaver comprises a memory having M logical memory units arranged in groups of N memory units such that accesses to memory units within a group are faster after a first access to a memory in that group using first access. An address generator is arranged to write consecutive data items a number of memory units apart that is less than the size of groups N of memory units so that two or more data items are written within groups. The arrangement provides fast interleaving without increasing memory size.
