Abstract: PURPOSE: A low complexity variable order short-term predictor for forming an MPEG-4 ALS VLSI is provided to reduce complexity when MPEG-4 ALS hardware is formed. CONSTITUTION: A pre-determining block(110) generates a modified prediction order in response to an inputted prediction order value. A loop controller(120) determines the numbers of repetition and flag signals in response to the modified prediction order value. An FIR(Finite Impulse Response) filter(160) receives a sampled signal. A pipeline stall is applied to the FIR filter according to radix-2 algorithm. The FIR filter filters the sampled signal. An output block(180) adds a determined result of the loop controller to a filtered output result of the FIR filter.
