Microprocessor device for controller of liquid crystal display device and related method

Abstract

The invention relates to a microprocessor device for a controller of a liquid crystal display device, which comprises a memory, a first processing unit, a second processing unit, a first moderator and a second moderator, wherein the memory is used for memorizing data; the first processing unit is used for carrying out a first program; the second processing unit is used for carrying out a second program; the first moderator is coupled between the first processing unit and the second processing unit and used for determining the sequence of the first processing unit and the second processing unit to carry out calculation; and the second moderator is coupled among the first processing unit, the second processing unit and the memory and used for determining the sequence of the first processing unit and the second processing unit to access the memory.

Description

technical field [0001] The present invention relates to a microprocessor device and related method for a liquid crystal display controller, in particular to a microprocessor device and related method for saving computing resources and component costs through the configuration of an arbitrator. Background technique [0002] A microprocessor (Micro Processor) device is a general term for the core unit of an electronic device, which may be composed of more than one processor. Under the dual-processor structure, the two processors operate independently in terms of software operation or hardware configuration. Please refer to figure 1 , figure 1 It is a schematic diagram of a conventional microprocessor device 10 . The microprocessor device 10 includes a main processing unit 100 , an auxiliary processing unit 102 , a first memory 104 , a second memory 106 , a main program memory 108 and an auxiliary program memory 110 . The main processing unit 100 is coupled to the first mem...

AI Technical Summary

Problems solved by technology

However, in the case of a large amount of data calculation, the microprocessor device 10 may reduce the computing performance of the microprocessor device 10 because the main processing unit 100 and the auxiliary processing unit 102 operate separately.

For example, if the microprocessor device 10 is applied to a liquid crystal display controller (LCD Controller), when the main processing unit 100 performs a large number of calculations on the zoom ratio of the screen, it cannot handle other tasks at the same time, causing the user of the liquid crystal display to feel system slows down

On the other hand, since the main processing unit 100 and the auxiliary processing unit 102 do not share memory, the resource allocation of the first memory 104 and a second memory 106 cannot be optimized, thus wasting production costs
