We do high-performance computing friends, presumably to the CPU implementation mode is already very familiar with it. Modern high-level CPUs typically use superscalar pipelining, which enables parallel execution of several mutually independent instructions-called instruction set parallelism (Ilp,instruction-level Parallelism), and SSE (streaming SIMD), like x86 introduced Extension), AVX (Advanced Vector Extension), and arm's neon technology belong to data-level parallelism (Data-level Paralleli

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

other hand, VRAM memory is limited, and if VRAM memory is used up, some data must be put into GTT memory.Usually GTT memory is on demand, and is used for devices, such as Radeon R600 graphics card can use up to 512M of system memory (this is set in the Linux kernel), a one-time allocation of 512M continuous memory for the device is not possible to succeed in the Linux system, And even if it succeeds, there

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

written cp_int_stat register.In the Radeon driver code, the Radeon_fence_emit function (referred to as the code in the GPU Command Pack chapter) is called after completion of filling the drawing command into the ring buffer, and the R600_fence_ring_emit function is eventually called on the R600 graphics card. The function has the following code:2327 void R600_fence_ring_emit (struct radeon_device *rdev,232

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

memory. The complete program that can run on R600 consists of two parts: a program that runs on the host (CPU), a program running on the R600 processor, part of the program called the shader program when processing graphics applications, and a program called Kernel when the GPU is used for general computing.Figure 1This section is all from the AMD manual "R600 instruction Set Architecture".2.

The first beta version of the Apple OS X 10.8.3 system has quietly supported the AMD Radeon HD 7000 series graphics card, which may mean that the graphics card is about to settle down with the new Mac Pro desktop computer team. The beta version of OS X 10.8.3 's support for the AMD
