description The invention provides an intra-frame predicting device and a prediction method suitable for the AVS coding. The device comprises a main controller, a calculation module, a selector and a mode judgingmodule, wherein, the main controller is used for coordinating the signal synchronization of the calculation module and the mode judging module, the calculation module adopts the parallel processing of five channels; when chroma subblocks 4 and 5 of a current macroblock are inserted between a current luma subblock 3 and the subsequent macroblock luma 0, the method greatly accelerates the processing, reduces the consumption of logic resources and can satisfy the requirements of real time high-definition coding.
