1. A method of data processing in a data processing system, said method comprising: in response to receiving pre-processed code, a compiler identifying a code section in the pre-processed code that is not candidate for acceleration and identifying a code block in the pre-processed code that is a candidate for acceleration, wherein the code block specifies an iterated operation; in response to identifying the code section, the compiler generating post-processed code containing one or more lower level instructions corresponding to the identified code section; in response to identifying the code block, the compiler creating and outputting an operation data structure separate from the post-processed code, wherein the operand data structure identifies the iterated operation; the compiler placing a block computation command in the post-processed code that invokes processing of the operation data structure to perform the iterated operation; and the compiler outputting the post-processed code.
