ABSTRACT:
The present invention relates to a programmable retargeter memory device which receives data being sent to addresses designated by the data and which retargets the data by replacing the addresses designated by the data with new addresses. The retargeter memory device of the present invention comprises an address memory and a data memory. The address memory comprises a plurality of address memory locations for storing retargeted addresses. The address memory is capable of being written to and read from to programmably alter the retargeted addresses stored therein and to output retargeted addresses therefrom. The data memory comprises a plurality of data memory locations for storing data associated with the retargeted addresses stored in the address memory and is capable of being written to and read from. Each data memory location is associated with one address memory location such that a write to a particular data memory location causes the retargeted address stored in the address memory location associated with the particular data memory location to be released from the address memory and sent to the location designated by the released retargeted address followed by the data written to the particular data memory location. The programmable retargeter memory device of the present invention can be provided with a release and re-order function which allows the data received by the programmable retargeter memory device of the present invention to be re-ordered before being sent to the retargeted addresses downstream.
