Core Graphics is a new generation of smart graphics, integrated in the intelligent processor, relying on the processor's powerful computing power and intelligent Energy efficiency adjustment design, with lower power to achieve the same outstanding graphics processing performance and smooth application experience. AMD's processor with core graphics is known as the APU (accelerating processor), and the processor of Intel's core graphics card is the SNB platform. Overview What is a co

Q: Often in newspapers and magazines to see the word dual core processor, what is the dual core meaning? What's the benefit? A: In simple terms, a dual-core processor is the integration of two CPUs on a single wafer. So what is a dual-core processor? What does the concept behind a dual-core processor mean, in short, a dual-core processor is a processor core that has two functions on one processor based on a single semi. In other words, two of the phy

So far, Intel has invested nearly 4.5 billion dollars in China and has four research and development institutions, and Intel is building Asia's first 300-millimeter wafer factory in Dalian, in addition to its two chip-packaging testing plants in Shanghai and Chengdu. At the same time, as a local corporate citizen, Intel actively fulfills its social responsibilities and cont

In image processing, the word mask is often encountered. So what does this word mean? Here's a quick explanation. 1. What is masking First of all, we look at what is the process of mask from a physical point of view.In semiconductor manufacturing, many chip process steps use lithography, a graphic "negative" for these steps called a mask (also known as a "mask"), which is used to cover an opaque graphic template in a selected area of the wafer, and t

BIN CHEN May 23, 2012, Evening 10:34 12 Some mobile phone players and enthusiasts are interested in the components of some mobile phones and even want to know how they work. Now, both mobile phones and tablets are basically built-in acceleration sensors to identify the direction of the device's rotation. Bill Hammack, an engineer from Illinois University, briefed us on how this acceleration sensor works and is not a tedious sermon, but an animated film to help explain it.Bill Hammack used Andr

, silicon substrates and their processing technologies have matured. Because silicon has many physical properties that people desire, such as its stable refractive index and easy to control, on a silicon wafer, passive devices can be integrated with lasers and sensors on the support frame. The optical integration circuit manufactured by SioB technology has sufficient density. A large number of chips can be produced after processing a single chip, mult

One of the quickest ways to determine the types of ready-to-use charts supported by JFreeChart is to check the Javadoc API documentation for the ChartFactory class of JFreeChart. In some development environments, you can use JFreeChart to effectively generate data-oriented charts, including: ◆ The generated file can be in PNG or JPEG format.◆ Java SE Swing-based applications, including applets◆ Java EE servlet and Ja

Java virtual machines. Unlike a virtual machine consisting of a general-purpose chip and interpreter, a Java chip can directly execute bytecode, that is, the bytecode is the instruction set of the Java chip. This hardware-based Virtual Machine is certainly much faster than a Simulated Virtual Machine. Sun plans to launch three types of Java chips: picoJava, mi-croJava, and ultraJava. PicoJava is a small Java kernel chip with a silicon wafer area of

, The larger piece of memory data is cached in the cache with higher read speed, as shown in the cache system is usually designed as a multi-tier mechanism, each layer has higher access speed than the next layer, but higher speed of the cache wafer is more expensive, so the higher speed of the cache tends to store more data volume, The first-level cache of the top tier is closer to the speed of the register, and the data access latency is hidden by th

The advanced embedded market is divided into the following three categories: ARM, DSP and FPGA. ARM is the industry leader, currently almost all Android smartphones use ARM authorized CPU architecture, while DSP (digital signal processor) has been widely used in the early years of the telephone, DVD, communication base Station and other fields. The difference between DSP and arm is that arm is a universal CPU,DSP and a dedicated CPU. FPGA is different from them, the name of the FPGA is due to th

"Test and encapsulation" should include this process.3. The calibration of the speed level depends not only on the quality of the chip itself, but also on the market positioning of the chip, rework probability and cost is also one of the factors.4. Chip grades can be adjusted and improved after testing, which is widely used in the pr

The advantage of AMP is the fine division of tasks, flexibility to adapt to different scenarios, make the best use, in order to optimally balance the cost, performance and power consumption. In addition, AMP is less difficult to program. As a result, AMP is more suitable for MCU applications than SMP.The AMP architecture has many advantages over standalone dual MCUs. It is critical to add a kernel that is much cheaper than adding a single MCU, especially if the two core architec
