The H265-MP-D IP core implements an HEVC/H.265 video decoder. The core complies with the Monochrome, Main, Main 10, and optionally the Monochrome 12, Main 4:2:2-10, and Main 4:2:2 12 profiles of the standard. The core is designed for trouble-free SoC integration. It operates on a stand-alone basis such that decoding proceeds without any assistance from the host processor. The core uses standard AMBA interfaces: AXI-Stream for input and decoded pixel data, AXI-lite for registers access, and AXI4 for the memory controller interface The H265-MP-D is a custom hardware accelerator and uses local memories that minimize external memory bandwidth, so its power consumption and clock frequency requirements are much lower than any software, or hybrid software/hardware decoder implementation.


    Device Utilization and Performance

    A minimal configuration of the core (4:2:0 (No 4:2:2), 8bit, No long term prediction, no PCM, No Tiles support, No WPP) synthesizes to about 140k ALMs, 730 DSPs, and 2.8M memory bits . A Full configuration of the core (i.e. All coding tools, all supported video formats and profiles) synthesizes to about 150K ALMs, 730 DSPs, and 9.2M memory bits. Depending on device family and speed grade the core can support rates of 720p30/60, 1080p3-/60, and 4kUHD@30.
