Abstract

A tile-based semi-global matching (SGM) processor with lossless data compression is proposed. The 8×8 tile-base processing and the P2-less data compression can reduce the external memory access by 85% without any change in the processing result. In addition, the P2-less data compression can decrease on-chip SRAM size by 50%. Implemented in 65nm CMOS technology, the 6.3mm2 chip consumes 288mW and supports 590MDE/s (million disparity estimation per second) when processing 640×360 resolution with 64-disparity range at 40fps real-time operation.
具有无损数据压缩功能的590MDE/s半全局匹配处理器
提出了一种基于块的半全局匹配(SGM)数据无损压缩处理器。8×8平铺处理和P2-less数据压缩可以在不改变处理结果的情况下减少85%的外部内存访问。此外,p_2 -less数据压缩可以将片上SRAM大小减少50%。这款6.3mm2的芯片采用65nm CMOS技术,功耗288mW,在处理640×360分辨率、64视差范围、40fps实时操作时,支持590MDE/s(每秒百万视差估计)。
