ABSTRACT:
A method and apparatus are disclosed for efficiently de-scrambling and bit-order-reversing one or more bytes of data according to DSL standards on a processor. In a preferred embodiment, this is achieved by providing an instruction for de-scrambling and bit-order-reversing one or more bytes of data according to DSL standards. Accordingly, the invention advantageously provides a processor with the ability to de-scramble and bit-order-reverse data with a single instruction thus allowing for more efficient and faster de-scrambling operations for subsequent processing.
