H.264/265 Video Encoder and Decoder IP

Description and Features

The Hardware Encoder Video Accelerator (HEVA), supports HEVC encoding low complexity with a flexible architecture targeting at least 1080p60 with minimal processing units and memory cuts and up to 2160p120 with large number of units and large memory cuts. Trade-off performance/area at design configuration: Reference cache size for 2160p30 at 350 MHz, 1 reference frame and bandwidth, overhead of 100% for references i.e. 1.5 GBytes/sec (minimal is 1.2 GB/s) Hardware interfaces :Host interface AXI3/AXI4 slave interface for the registers and command/status FIFO, Memory interface AXI3/AXI4 Streaming interfaces to External DRAM, Asynchronous AXI3/AXI4 128 bits interface, Synchronous DMA arbiter and memory interface Task sequencing modules: Manages communication and storage between processing modules, Control the shared memories and caches between the TPU modules and TSU/MIF, Defines the execution mode of the task processing units Task processing modules: Perform the pixel and bit-stream processing under control of TCR/TSU, The number of processing elements is defined at design configuration to sustain the required performance, A local reference cache is needed for performance for some processing units.
