Abstract
This paper presents a DTMB deinterleaver structure to reduce SDRAM power consumption. DTMB, the Chinese digital TV standard, has a deinterleaver that consists of many long delay buffers. SDRAM is used for this deinterleaver. The proposed structure pairs data and transfer a pair with an SDRAM transfer. With the reduction of the SDRAM operation number, the proposed structure can save the SDRAM power consumption by around 35%.
