Estimated global semiconductor sales in 2012 will reach US$323.2 billion (approximately NT$9,667 million), a slight increase of 3.3% from 312.8 billion US dollars in 2011, but only 1.25% of the global semiconductor industry's turnover in 2011. The annual growth rate is slightly improved.
If the economic conditions in the United States and other regions begin to recover in 2013, the growth of the semiconductor industry is expected to rejuvenate. It is estimated that between 2013 and 2015, the annual growth rate of semiconductor revenue will reach 6.6 to 7.9% between 2015 and 2015. Industry turnover can climb to US$397.7 billion (1.1771 trillion U.S. dollars).
The main reasons for the slow growth of the semiconductor industry in 2011 and 2012 were caused by external factors, economic recession, and various problems in the United States, Europe, Japan, and the Middle East. The global economy is not strong enough to drive growth, and semiconductors are therefore trapped. Difficulties.
Q2 orders are expected to be rejuvenated consumers are also a key factor affecting the growth of the semiconductor industry, although in the end of 2011 shopping season in Europe and America, consumers buy a lot of electronic products, thus reducing semiconductor inventory, but this is not enough for semiconductor demand increase.
What's worse is that in the third quarter of 2011, many companies reduced capacity utilization and reduced inventory pressure. However, these efforts could not reduce inventory enough to make new orders appear. As a result, orders from semiconductor manufacturers have continued to slump and it will be necessary to wait until the second quarter of this year.
The lackluster demand for foundry performance has a comprehensive impact on the semiconductor industry. Taking IDM (Integrated Device Manufacturers) as an example, the lack of demand leads to poor capacity utilization, so IDM wants to maintain the inefficient Crystal. The round plant operation, under pressure to double, leading to improved capital expenditures, was postponed to 2013.
For the semiconductor industry, the first half of 2012 is undoubtedly a difficult time. In the first quarter of the traditional off-season, semiconductor sales will decline, and then it will continue to rebound in the second quarter and rebound strongly in the third quarter. This is The pace of seasonal growth in the traditional typical semiconductor industry will be followed this year. There is no accident.
The performance of the foundry industry will be better than that of the overall semiconductor industry, especially the foundry with advanced production capacity. The main reason is that the market for wireless communications applications has grown rapidly, and the major components of many wireless communications devices require advanced semiconductor processing.
From the perspective of the needs of major semiconductor users, global brand manufacturers’ purchases of semiconductors in 2011 amounted to US$240.6 billion, a 5% increase from the US$231 billion in 2010. It is estimated that the purchase amount of global brand manufacturer semiconductors this year will rise by another 3% to reach 247.8 billion U.S. dollars (7,334 billion U.S. dollars).
From the perspective of the application of semiconductor manufacturers' purchases in 2011, the amount of wireless communication is the highest, reaching 65.1 billion U.S. dollars, accounting for 24% of all purchases. The application of wireless communications has expanded, mainly thanks to the iPhone, iPad and smart phones.
The RGB Color Controller is in a predetermined order to change the main circuit or control circuit wiring and circuit changes the resistance value to control the motor start, speed, braking and reverse master device to control RGB color.
Cumbersome, complex structure, once the design is complete, you can not modify or expand, but it's fast. Micro-controller design program easy, simple structure, convenient to modify or expand, modify a machine instruction function, simply restated the corresponding micro-program;
To add a machine instruction, just add some micro-control program in memory, however, RGB Color Controller is through the implementation of a micro program.
Specific comparison is as follows: a combination of hardwired logic controller, also known as the controller, by the logic circuit, relies entirely on hardware to achieve the function of the instruction.
Basic components to RGB Color Controller:
(1) the instruction register is used to store instruction being executed.
(2) Operation code decoder: instruction opcodes for decoding to produce the corresponding control level, to complete the analysis function of the instruction.
(3) Sequential Circuits: used to generate a time stamp signal.
Mingxue Optoelectronics Co.,Ltd. has apply the I S O 9 0 0 1: 2 0 0 8 international quality management system certificate, For RGB Color Controller we apply the CE, RoHS and SAA certificate for our led lighting product.
