must execute the same command, therefore, this control statement is split into two executions [Branch prediction is performed in the compilation phase.]. For the first time, the odd thread of branch a executes, the even thread performs the null operation, the second even thread executes, and the odd thread does the null operation. The hardware system has a 64-bit mask register. For the first time, it is 01... 0101, the second operation will be reversed. 10
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.
In August 14, the amd chief executive team,
Asynchronous modules define AMD and asynchronous modules amd
It is called Asynchronous Module Definition, and is defined by Asynchronous components (or modules. AMD is a mechanism in which components and their dependencies can be asynchronously loaded.Define Method

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
Original: http://villadora.me/2014/05/23/amd-define-and-how-to-translate-amd-to-commonjs/There has been a lot of controversy between Commonjs and AMD, and both have evolved and converged on the project. Personally, Commonjs is more developer-oriented, and for developers, it requires a clear version and management, less code and more interference, and less configu
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
The previous blogs have described some of the DRM drivers, graphics card memory management mechanisms, and interrupt mechanisms, and it should be much easier to read the AMD DRM-driven initialization process.Here is an article written by an AMD developer (put it here for the time being, and then add your own view later).Understanding GPUs from the ground upI get asked a lot on learning how to program GPUs.
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.

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

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
