Abstract
A semiconductor memory is used to retain execution code and data for a CPU and display data for a liquid crystal controller, also used as a temporary work memory to be used when moving picture data such as MPEG is subject to a decoding process, and also used to retain decoded moving picture data.
Claims8
A liquid crystal display apparatus comprising:
- a liquid crystal display panel equipped with a common driving driver and a line driving driver;
- a device that transfers display data to the liquid crystal display panel;
- a semiconductor memory that retains data;
- and
- a device that decodes MPEG data,
- a unified memory architecture that the semiconductor memory retains execution code and data for a central processing unit and display data for the a device that transfers display data to the liquid crystal display panel, is also used as a temporary work storage used when a process of decoding moving picture data such as MEPG is conducted, and also is used to retain decoded moving picture data.
