摘要：
A turbo decoder stores received data in words in systematic memory and parity memory in a way that is known that it will be used for later iterations by turbo decoder engines arranged to operate in parallel. A loader receives and separates LLRs into systematic and parity data and stores them into a portion of a word per cycle until a word is full in a corresponding one of the systematic memory and parity memory. The turbo decoder engines read the LLRs from one word of the systematic memory and one word of the parity memory in a single cycle. The data can be rearranged within the words in an order format for the turbo decoder engines to later read them by providing sub-words corresponding to respective ones of the plurality of turbo decoder engines.
