3. Architecture for parallel marker-free variable length streams decoding. Yousef Baroud; José Manuel Mariños Velarde; Zhe Wang; Steffen Kieß; Seyyed Mahdi Najmabadi; Jajnabalkya Guhathakurta and Sven Simon. Journal of Real-Time Image Processing 16, 6 (December 2019), pp. 2127–2146. DOI: https://doi.org/10.1007/s11554-017-0715-2
  Abstract
  Due to throughput requirements above 1 gigapixel/sec for the real-time compression of modern image and video data streams, parallelism for encoding and decoding is inevitable. To achieve parallel decoding, a well-established technique is to insert markers into the variable length code (VLC) stream. By locating markers, it is then possible to extract the sub-streams that are, in turn, decoded in parallel. The use of markers adversely affects compression especially when a high degree of parallelism is required. In this paper, we propose an architecture of a marker-free parallel decoding approach of VLC streams. Instead of multiple local entropy decoders, the proposed architecture is based on using a single parallel entropy decoder in conjunction with a novel format to construct the VLC stream. The approach runs at high clock rates supporting parallelism to a high number of decoders. A synthesized clock frequency well above 110 MHz is achieved for up to 20 decoders on a medium-sized FPGA.
