Abstract

This invention relates to a controlling device between function module and external memory of digital television, which comprises: function module, used for changing format and storing the place of input and output image; the storage controller, used for receiving data and image place information from the function module and transferring to the place information of external memory; the buffer controller with the interface function of function module and storage controller, used for constituting data arrange format according to the type of the external memory and the data arrangement format of the controlling signal which is received from the storage controller; the memory address generator, used for generating data place information in memory according to the changed place information; the buffer controlling signal generator, used for generating the data arrangement type signal according to the data place information.

Description

technical field [0001] The invention relates to digital broadcasting, in particular to a control device between a function module and an external memory on a digital television. Background technique [0002] Digital TV can process input and output signals and perform format changes, and the functional modules responsible for this format change can be connected to any position of input and output images. [0003] In order to perform the above access function, the image data will be processed and saved in the external memory, and the storage control device will receive the data and image location information processed by the functional module, convert it into the location information of the external memory, and save the data accordingly . [0004] The function module sends a request signal to the external memory controller to occupy the space of the external memory through the buffer controller in its own time zone, and the external memory controller moves closer to the memor...
