1. R600 3D EngineThe R600 core is a very important GPU core of AMD, which introduces a unified processor architecture, with registers and instruction sets that are completely different from the previous GPUs and have a big difference in their programming.Figure 1 shows the hardware logic diagram of the R600 GPU core, t
Earlier graphics cards were only used for display, and then 2D acceleration components were added to the graphics card, which were used for the operation of the screen, draw points, draw lines, and so on. With the need of game, three-dimensional simulation and scientific computing visualization, the demand for 3D is gradually increasing, the early drawing work is done by the CPU, to achieve realism and real-time effect, can only draw some simple wireframe model, in the 80 's, Stanford University
queue.The 2703 line involves the fence mechanism, which we'll cover in detail in the interrupt mechanism section.The same code that reads the indirect buffer mechanism is not too difficult.Indirect buffer to be able to function properly, it must be inserted into the code of the ring buffer, which is similar to inserting a "call xx" directive into the assembly code for function calls. The command added by the Radeon_ring_ib_execute function is equivalent to the call instruction used when the fun

To write a complete program, you can refer to the LIBDRM source code or the
scratch register will tell you which interrupt was generated by the drawing command.The fence interrupt handler function is radeon_fence_poll_locked. First read the fence number, know that the fence operation caused the interruption, when the resulting interrupt fence number is the last number, you need to assign the last fence number to the current number, while updating the fence timer. If the interrupt is not the last fence number, the timer needs to be judged and then the fence interrupt qu
often tied to both the S-video and a VGA port or the Analog portion of a dvi-i port). The mapping is important as you need to know what encoders be in use and what they be tied to in order to program the DI Splays properly.Radeon_hpd_init () is a macro, points to the Asics specific function to initializes the HPD (hot Plug Detect) hardware F or digital monitors. HPD allows a interrupt when a digital monitor is connected or disconnected. When this happens the driver would take appropriate action

Although AMD's day-to-day task is to zen the momentum, but after all Zen the fastest also have to be the end of the year or the beginning of the IPO. In such a gap, the addition of the upgrade is the pain before the dawn. As a representative of AMD High-performance CPU--FX series, although its historical evaluation has long been conclude, but the market always has a place for the FX series. This year, AMD s

Personally, Commonjs is more developer-oriented, and for developers, it requires a clear version and management, less code and more interference, and less configu
This one test is the flagship model of the next generation of "Bristoal Ridge" processors: a12-9800. Compared to the previous generation of APU, this generation of AMD CPUs supports ddr4-2400 memory, NMVE protocol SSD, providing greater bandwidth and support for USB 3.1. From the extended functionality to catch up with Intel's mainstream processor. Let's take a look at the CPU performance of the a12-9800.

Article title: AMD released StreamSDKforLinux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
At the beginning of this month, it was reported that AMD will release Stream SDK for linux at the end of the month. AMD was not dis
After restructuring, acceleration, and comprehensive transformation, AMD has been reborn. A brand new future-oriented AMD will take into account the traditional PC business and emerging business markets, and face the challenges of the cloud computing era with innovative technology, unique vision and powerful execution.

While DIY players are casting their eyes on Intel's six-generation processor this year, AMD, the Intel's nemesis, also listed a new AMD Fast Dragon II X4 870K processor, which is similar to AMD 860K, shielding the core graphics card, the flagship multicore high performance, Recommended for mainstream gamers who need to be equipped with independent graphics.

module exports, and loaded indicates whether the module is loaded. There are also many properties, which are omitted here.When you need to use this module later, you will be taken to the exports attribute. Even if the Require command is executed again, the module is not executed again, but the value is taken to the cache.Math.jsexports.add = function (A, b) {return a + B;}var math = require (' math '); Math.add (2, 3); 512Since COMMONJS is a synchronous load module, this is not a problem for th
Modular architectureBefore learning about AMD and CMD specifications, you still need to first briefly understand what is modular and modular development?Modularization refers to the systemic decomposition of a problem according to a classification of thinking when solving a complex problem or a series of Mixed Problems. Modularization is a way to process complicated systems into manageable modules with a more reasonable code structure and higher maint
use.First, since it is a modular design, the ability to act as a modular system: 1.Defines the encapsulated module.2. Define the dependencies of the new modules on other modules.3. Can support the introduction of other modules. Well, thought has, then always have something to build a modular system of norms, otherwise all kinds of module loading will only make the bureau more chaotic. Then in JavaScript there are some non-traditional module development methods of the Specification COMMONJS modu
