摘要： Provided are an LDPC decoding apparatus and method using a sequential decoding algorithm having a partial group, capable of reducing the number of an iterative decoding by more than half without degrading the performance and increasing an amount of computation. The LDPC decoding method includes the steps of: receiving a prior probability information (channel values) based on information on channel values associated with distance between symbol signals in constellation related to the received noise and LDPC encoded data, and initializing bit nodes; dividing check nodes into partial groups before updating check node information based on the prior probability information, and performing a decoding by applying a sequential decoding algorithm; determining whether a parity check equations are satisfied; and outputting decoded messages obtained when satisfying the parity check equation or after terminating an iterative processor by a termination algorithm.

摘要： An image forming apparatus, a microcontroller, and methods for controlling the image forming apparatus and the microcontroller are provided. The microcontroller include: a memory controller which is connected to an external memory operating in a self-refresh mode if a normal mode changes to a low power mode and outputs a preset signal which is to cancel the self-refresh mode if the low power mode changes to the normal mode; a memory interface unit which transmits the preset signal to a main memory; and a signal detector which detects whether the preset signal has been output. Here, the memory controller powers off the memory interface unit if the normal mode changes to the low power mode and powers on the memory interface unit if the low power mode changes to the normal mode, and the output of the preset signal is detected by the signal detector.
