Method and apparatus for dynamically resizing a frame buffer in a shared memory buffer architecture system

摘要

A method and system for dynamically sizing a dedicated memory in a shared memory buffer architecture. At initial boot, system BIOS programs control register to allocate a dedicated memory of a desired size. The size of the dedicated memory allocated is dependent on the performance requirements. If after initial boot, the performance requirements change, it may necessitate a change in dedicated memory size. By reprogramming the control registers, the dedicated memory size is dynamically changed without any manual manipulation of internal components.
