Title: Coding method, device, system with merge mode
Inventor: ESENLIK SEMIH
IPC: H04N19/70
Filed: 2019-08-12
Abstract: An apparatus and method for marking availability of a candidate coding block for merge estimation of a current coding block within a coding tree unit, CTU, which includes multiple coding blocks. Initially, the candidate coding block is marked as available. The candidate coding block is marked as unavailable when a predefined location of the candidate coding block is included within an extended merge estimation region, MER. The extended MER includes a current MER in which the current coding block is located and at least a portion of another MER, adjacent to the current MER. The predefined location may be a top-left or bottom-right (pixel) position of a corner of the candidate coding block. Whether the candidate coding block is located within the extended MER is determined in dependence on the positional relation between the predefined location and a position of a corner of the current coding block, with the corner being any of the upper-left, bottom-left, or bottom-right. The coding blocks may be labelled based on a processing order and grouped using a slid window. When the candidate and current coding blocks are in the same group, the candidate coding block is marked as unavailable.

Abstract: 一种外部设备访问计算机内存的方法，包括步骤：所述外部设备向计算机申请一定大小的内存空间，并接收所述计算机反馈的多个内存块；所述外部设备通过顺序存储结构或链式存储结构建立外部设备和计算机的内存映射关系；当所述外部设备发起读写操作，根据所述外部设备和计算机的内存映射关系找到计算机中对应的偏移地址，生成读写操作猝发指令，在计算机的内存上实现读写操作。该方法可以实现快速地连续地访问计算机内存的多个不连续内存区域，提升计算机操作系统和外部设备访问内存的速度。
