Embodiment Construction

[0045] Some embodiments of the present invention provide a method and system for providing 1080p video using 32-bit mobile double data rate (DDR) memory. In various embodiments of the present invention, a method for video processing may include utilizing multimedia processing communicatively coupled to a single second generation low power double data rate memory (LPDDR2) synchronous dynamic random access memory (SDRAM) The processor processes video data, with a multimedia processor and a single LPDDR2 SDRAM in a single package on a single substrate. The above processing may include the multimedia processor accessing a single LPDDR2 SDRAM during processing of the video data. A single LPDDR2 SDRAM can include a 32-bit wide access bus. In this regard, a multimedia processor can be used to access a single LPDDR2 SDRAM with a 32-bit wide bus access. The processed video data may include video data in a 1080 progressive (1080 progressive, 1080p) high definition television (HDTV) fo...

Abstract

A method and system for video processing are provided in which a multimedia processor and a single low power double data rate memory 2 (LPDDR2) synchronous dynamic random access memory (SDRAM) coupled to the multimedia processor are disposed in a single package on a single substrate or chip. The single LPDDR2 SDRAM may be accessed by the multimedia processor via a 32-bit wide access bus. The multimedia processor and single LPDDR2 SDRAM may be operable to process video data. The video data may comprise 1080 progressive (1080p) high-definition television (HDTV) formatted data. The multimedia processor and single LPDDR2 SDRAM may be operable to pipeline process video data from an image sensor.

Description

technical field [0001] The present invention relates to communication systems. More particularly, the present invention relates to providing 1080 progressive (1080p) video using 32-bit mobile double data rate (DDR) memory. Background technique [0002] Many devices have image and video capabilities, such as mobile phones, personal digital assistants, digital televisions, digital live broadcast systems, digital recording devices, game consoles, and the like. But processing video data will be computationally intensive due to the need to constantly move large amounts of data. Therefore, systems with powerful processors, hardware accelerators and / or large amounts of memory are often required, especially when video encoding is required. Such systems typically use a lot of power, which may render them unsuitable for some applications, such as mobile applications. [0003] Due to the growing demand for image and video capabilities, there is a need for an energy-efficient, high-p...
