H.265/HEVC is the ISO/IEC standard for video compression and decompression. H.265/HEVC which has double compression performance of the H.264/AVC video compression standard, is expected to be used for high-definition video distribution such as 4K (3840 x 2160) and 8K (7680 x 4320), as well as video distribution services for mobile devices on the limited bandwidth.
We have developed and commercialized a software H.265/HEVC encoder.

What is NUMA architecture?
NUMA is an architecture for shared-memory multiprocessor computer systems, in which the cost of accessing the main memory shared by multiple processors is not uniform, depending on the memory area and processor. There are multiple processor-memory pairs (called Node), and from the perspective of a given processor, memory on the same node is called Local Memory, while memory on other nodes is called Remote Memory. Local Memory access latency < Remote Memory access latency If the processor does not need to refer to the memory frequently, it is called Local Memory. By placing data that processors need to refer to frequently in memory with low access cost, and placing data that is not frequently referred to in memory with high access cost, bus congestion is prevented and bus clocking is improved by reducing the number of processors sharing the bus.
