However, if the tile needs to be fetched from top to bottom, it will result in frequent cache misses
Frequent cache misses increase memory access latency as page entries are fetched from system memory such as Dynamic Random Access Memory (DRAM)

Embodiment Construction

[0032] While this specification includes claims defining features of one or more implementations of the invention which are believed to be novel, it is believed that the circuits and methods will be better understood from a consideration of the description in conjunction with the accompanying drawings. Although various circuits and methods are disclosed, it is to be understood that the circuits and methods are merely examples of arrangements of the invention, which may be embodied in a variety of forms. Therefore, specific structural and functional details disclosed in this specification are not to be interpreted as limiting, but merely as a basis for the claims and as a basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure. A representative basis for the arrangement. Furthermore, the terms and phrases used herein are not intended to be limiting but to provide an understandable description of the c...

Abstract

A method for processing of a video stream is described. The method comprises receiving the video stream captured by a first sensor, dividing, for each of a plurality of frames of the video stream, into vertical slices having a slice width, and storing the divided each of the plurality of frames in a re-ordered slice based format. Computer-readable storage medium and a device for processing of a video stream are also described.

Description

technical field [0001] Embodiments of the present invention generally relate to image processing apparatuses, and in particular, to an apparatus and method for implementing image processing. Background technique [0002] Digital image processing has become very common and important in many fields. Digital image processing takes images from sensors and converts them into visual content. However, digital image processing (including multi-frame image processing) may require substantial resources of an image processing device, such as a digital camera, which may be implemented in a portable computer or communication device. When accessing data of one or more frames captured by an image processing device, the formatting of the data is beneficial for reducing system latency and improving memory bandwidth. In modern SoCs, the IP typically accesses system memory (such as DDR) through the system MMU, which provides the IP with a contiguous (ie, virtual) view of the memory and perfo...
