Abstract
An apparatus and method for efficiently performing error control coding tasks. An important aspect of the present invention is the provision of an ECC engine that responds to a specialized ECC instruction set having a plurality of instructions, such as a convolutional encoding instruction, a convolutional decoding instruction, and a cyclic redundancy code (CRC) instruction. The ECC engine has a plurality of functional building blocks (e.g., a configurable convolutional encoding functional block, a convolutional configurable decoding functional block, and a configurable cyclic redundancy check (CRC) functional block) that can be programmed or configured. A single instruction provided to the error control coding engine configures one of the functional blocks to execute a error control coding algorithm specified by the instruction. Each instruction also includes a plurality of fields that can be modified by the user. Each modified instruction dynamically re-configures one of the functional building blocks to implement a different ECC algorithm.
