HT die is increased by 5% compared with the previous P4. The remaining parts, such as ALU, FPU, and L2 cache, remain unchanged. Although hyper-threading technology can be used to execute two threads at the same time, each CPU has independent resources, not just like two real CPUs. When both threads need a certain resource at the same time, one of them must be temporarily stopped and the resources must be made available until these resources are idle.

The position of the horizontal shadow. Negative values are allowed. Test V-shadow Necessary. The position of the vertical shadow. Negative values are allowed. Test Blur Optional. Blur distance.

The rasterized fragments are sent to the SPI and then into the shader core for final fragment processing. The fragment processor takes textures, ALU calculations, and memory read and write operations. Upon completion, the geometry information of the fragment (coordinates in the screen coordinate system and depth values) and color informatio

I will try to write this article with the simplest and clearest ideas.The so-called memory addressing is the process of translating from the address written in the instruction to the actual physical address. Because the operating system has to take care of a lot of things, it becomes complicated.logical address → linear address → physical addressLogical address = segment + OffsetBecause: the alu width in the first CPU is only 16 bits, but the address

Of course, the 32-bit operating system installed on 64-bit computers, its hardware is like "Big Horse Cart": 64-bit performance will be greatly reduced. 3rd, the operation speed is different 64-bit CPU GPRs (general-purpose registers, universal Register) data width of 64 bits, 64-bit instruction set can run 64-bit data instruction, that is, the processor can extract 64 bit data at a time (as long as two instructions, a single extraction of 8 bytes of data), Up to 32 bits (four inst

memory, decoding will use the instruction Register group, the implementation will use the ALU, A register group is required to write back. That is, because each step can be done with different hardware, the CPU engineers invent pipelining to execute instructions. What does that mean. If you need to wash the car, the car wash will carry out the "car Wash" command, however, the car wash shop will be separate operation, such as flushing, foam, washing,

is the DSP simulation interface, DSP also provides HPI port, this interface can be connected with the computer, you can download files in the computer and through the DA Play, you can also transfer digital voice signal to the computer to save and processing. The DSP in the system adopts OMAP5910, the DSP is the embedded DSP which is launched by TI Company, has the dual processor structure, the chip integrates arm and DSP processor. ARM is used to control peripheral devices and DSP is used for

It is used to temporarily store the operational data in the CPU, as well as the data exchanged with ext

occur. CUDA provides APIs to synchronize threads in the same block to ensure that all threads reach a certain time point before the next step. However, we do not have any atomic operations to ensure internal synchronization of the block. Threads in the same warp can be executed in any order, and active warps are limited by SM resources. When a warp is idle, the SM can schedule another available warp in the SM. There is no consumption for switching between concurrent warp, because the hardware r

browser only needs to be drawn once to form a picture. Using only one Canvas DOM element, reducing the number of DOM and rendering complexity, can turn the original CPU-intensive into GPU operations. The vast majority of Canvas is accelerated rendering with hardware GPU. The ALU (computational unit) of the GPU is much more than the CPU, while the control operation (logic) can be done in the CPU with JavaScript, and even CPU-intensive ope

), which is 32-bit (four instructions are required to extract 4 bytes of data at a time) the performance is doubled in theory.Fourth, different addressing capabilities. The advantage of a 64-bit processor lies in the system's memory control. Because the address uses a special integer, An ALU (Arithmetic Logic calculator) and register can process larger integers, that is, larger addresses. For example, Windows Vista x64 Edition supports up to 128 GB of

Comments: First, let's talk about common registers. 1 CPU Composition CPU can be roughly divided into the following three parts:(1) The arithmetic logic Part ALU (arithmetic logic unit) is used for arithmetic and logical operations.(2) control logic.(3) working register, each register is equivalent to a storage unit in the memory, but it is fast to access. It is used to store information required or obtained during an operation, including the operand

any registers. User, interrupt, and exception abort. Both superuser and undefined mode have two private registers, R13 and R14. Each of these modes can have a private Stack pointer and link register. Program Status Register ARM920T has one current Program Status Register (CPSR), and five other program State registers (spsrs) for exception interrupt processing. The functions of these registers include: Keep the information about the recently completed ALU
