摘 要:正This paper proposed a VLSI architecture of Embedded Block Coding with Optimized Truncation(EBCOT) Tier-2 encoder for *** on a Rate-Distortion(RD) slope method,the proposed architecture eliminate the iteration of the RD truncation,reduces the scale of the on-chip bit-stream buffering from full tile size down to three-code-block size and at the same time,accurately control the compression bit-rate with 95%*** proposed Tier-2 encoder has already been integrated into the JPEG2000 codec and fabricated with SMIC 0.18um 1P6M CMOS technology.
