Application ID: 12689636

Base Claim:
1. An apparatus comprising a circuit that includes: first and second data interfaces for parallel transfer of data having respective first and second word widths that are each multi-bit and different; a data transfer portion that manipulates data arriving at the first data interface with the first word width into data with the second word width, the data transfer portion transferring the manipulated data to the second data interface; and configurable structure that specifies one of the first or second word widths is a selected one of a plurality of different word widths, including a field-programmable device that includes the circuit, wherein during field programming of the device the configurable structure is configured to specify the selected one of the plurality of different word widths.

Claim 2:
2. An apparatus according to claim 1 , wherein the first word width is an integer multiple of the second word width; wherein the data transfer portion carries out the manipulation in a manner that includes dividing a first data word with the first word width from the first data interface into a plurality of second data words that each have the second word width; and wherein the data transfer portion carries out the transferring in a manner that includes supplying the second data words successively to the second data interface.
