Embodiment 1

[0018] Example 1. A TV set adopting main and auxiliary double microprocessors, which includes a shell and an electronic circuit installed in the shell, and the electronic circuit includes a microprocessor circuit. The microprocessor circuit includes a main microprocessor (1) and a secondary microprocessor (2). Infrared remote control signal and button signal are input to main and auxiliary microprocessor (1) and (2) simultaneously, and main and auxiliary microprocessor (1) and (2) all hang on I 2 on the C bus. They are also connected through another I / O port (3). The main microprocessor (1) also has an external flash memory FLASH and an RS232 interface that can be externally connected to a PC.

[0019] The main microprocessor (1) and (2) are also connected with the specific I / O port (4) that can be sent by the main microprocessor (1) to send the timing shutdown effective information to the secondary microprocessor (2). .

[0020] What the main microprocessor (1) adopts is...

Abstract

Disclosed a TV set which uses a main-sub two-chip microprocessor, comprises a housing and a electronic circuit, wherein, the electronic circuit comprises a microprocessor circuit which includes a main microprocessor and a sub-microprocessor while the infrared control signal and the key-press signal are input to said two processors at one time. These two processor are both connected to the I2C bus, while a I / O port connects them. The main microprocessor also has a external flash memory and a RS232 interface while a special I / O port which can send the time switch-off effect information from the main microprocessor to the sub-microprocessor connects these two microprocessors. In addition, the main microprocessor uses the 16 bits X86 microprocessor of PHOTOPIA of PW Company and the sub-microprocessor uses the ATMEG8 of Atmel Company. The invention solves the conflict between high property and high power consumption, while it improves the property of TV, with significantly reduced power consumption. The invention can be used in family, hotel and the write building.

Description

technical field [0001] The invention belongs to the technical field of television sets, and more specifically relates to the design of a television set using main and secondary microprocessors. Background technique [0002] With the development of digital TV signal processing technology and the popularization of digital multimedia technology, the performance of the microprocessor (CPU) as its core has also been rapidly improved, and its processing speed and processing functions are not what they used to be. However, it is followed by a sharp increase in power consumption. Some models use PW's 16-bit X86 core microprocessor PHOTOPIA with powerful image processing functions, and the power consumption is between 3 and 4W. In other words, the high performance of TV sets in the past inevitably brought high power consumption. [0003] Today, with international and domestic requirements for environmental protection and energy saving, high power consumption h...
