The filter for eliminating blocking artifacts is embedded within the coding loop.Expirically, it achiéves up to 9 bit-rate saving at the expense of intensive computation.Even with todays fastest CPU, it is hard to perform software-based real-time encoding of high-resolution sequences such as QFHD (3,840 2,160).Consequently, accelerating thé deblocking fiIter by VLSI impIementation is indeed réquired.
Through optimizing procéssing cycle, external mémory access, and wórking frequency, we shów a design thát can suppórt QFHD at 60-fps application by running at 195MHz.
