Abstract

The invention provides a special self-programmable chip for a remote controller. The special self-programmable chip comprises a logic control unit for identifying keystrokes of the remote controller and controlling emission of remote control codes, and a memory unit connected with the logic control unit and used for storing the remote control codes and the code patterns to be read by the logic control unit. According to the invention, the solution that the control chip of the remote controller has the minimum cost is realized under the premise that the maximum flexibility is kept. The novel structure provided by the invention breaks through the traditional limitation, integrates the advantages of two implementation methods in the prior art and compensates shortcomings in the prior art.

Description

technical field [0001] The present invention relates to the technical field of embedded systems, and in particular, to a self-programmable remote control dedicated chip. Background technique [0002] In the prior art, there are generally two implementations of the dedicated chip for the remote control: [0003] 1. Realize with MCU (Micro Control Unit) [0004] figure 1 It is a simple schematic diagram of the internal module structure of a special chip for remote control in the prior art. like figure 1 As shown, the remote control dedicated chip 100 may include a central processing unit (CPU) 101, a control logic unit 102, a program space unit 103, etc., and realize the output of various remote control codes through programs. Wherein, the program space unit 103 may be a programmable non-volatile memory. However, the above implementation with MCU has the following disadvantages: [0005] a. The cost is high, and the implementation of ROM and CPU requires a lot of hardwar...
