Abstract
An apparatus and method for extracting and loading data to/from a buffer are described. The method includes the selection of data from a data buffer in response to execution of a data access instruction. The data buffer includes a plurality of data storage devices, one or more of which initially contain the selected data. Accordingly, the plurality of data storage devices form a single address space that is addressable at a bit-level. When the selected data spans from a source data storage device to a next data storage device of the data buffer, a portion of the selected data from source data storage device is concatenated with a remaining portion of the selected data from the next data storage device to form the selected data as a contiguous unit. Finally, once the selected data is formed, the selected data is stored within a destination data storage device.
