A linear frame buffer, also known as LFB, refers to a computer memory structure that is used to store images and graphical data in a sequential and linear manner. It is a vital component of the graphics rendering process that enables the display of visual content on a computer screen.
In a linear frame buffer, pixels are arranged in a contiguous sequence, with each pixel represented by a fixed amount of memory. The memory organization is typically in a linear array of rows and columns, where adjacent pixels are stored one after another in memory. This linear arrangement allows for efficient and straightforward access to individual pixels.
The purpose of a linear frame buffer is to provide a canvas for rendering graphics, where images, textures, geometries, and other visual elements can be stored in a way that allows for fast and direct manipulation. It is commonly used in graphics processing units (GPUs) and graphics libraries to handle real-time rendering of 2D and 3D graphics.
By having a linear frame buffer, graphics processors can read, modify, and write pixels directly, enabling efficient rendering and manipulation of graphical content. The linear arrangement also facilitates various operations, such as rasterization, blending, and anti-aliasing. Additionally, it allows for quick data transfers between the frame buffer and the display device, resulting in smooth and responsive visuals on the screen.
Overall, a linear frame buffer acts as a critical memory structure in computer graphics systems, facilitating the storage, retrieval, and manipulation of pixels to achieve high-quality and real-time rendering of images and graphical content.
