Abstract
Abstract A first addressable memory stores data received from an external source. The data addresses storage locations in a second memory which also stores data received from an external source. Registers and logic are provided for transferring data between the memories. Data is stored in the second memory and address locations for the second memory are stored in the first memory in accordance with a desired data order. The first memory is addressed and the address data in its locations is replaced by data from the second memory in a desired order. Subsequently, it is read out from an output register.
