At present, the main types of video memory used in the market are sdram,ddr sdram,ddr sgram two kinds. Sdram SDRAM is the abbreviation of synchronous dram, meaning: synchronous dynamic random memory. It works in sync with the graph bus, avoids the extra wait time required to operate the asynchronous DRAM on the system bus, and speeds up the data transmission. Development experience:

background This series of summary should be accompanied by the project in a timely manner, but for the graphics card driver, itself can refer to very little information, only from the kernel code to do not try to figure it out. The purpose of the project is actually very simple and rude, why do you say so, because the work to be done involves implementing a 2D hardware accelerator on the embedded device, capable of supporting Mesa Open source 3D Graphics library, EGL,DLX and DRM modules.

Linus Torvalds announces the 3.12 stable version of the kernel, bringing a number of driver updates and improvements, such as Radeon Graphics, AMD APU, Qualcomm Owl/adreno,nvidia Optimus, various file systems and other driver updates. Linus in the mailing list said: "I was hesitant to come to a RC8, but next week to travel, the internet is not good, or no delay." And said that after 3.19 will enter the 4.0 era, but that is a year later things. New f

DDR2 Circuit DesignHigh-speed large-capacity cache is an essential hardware in high-speed big data applications. At present, the use of a wide range of high-speed large-capacity memory in FPGA system has a classical low-speed single data rate of SDRAM memory, and high-speed dual-rate DDR, DDR2, DDR3 type SDRAM memory, The DDR series of memory all require the FPGA chip has the corresponding hardware circuit

SCCM TP4 Configuration Discovery methodSome configurations are required to initialize the SCCM server that has just been installed. SCCM Discovery identifies the computers and user resources that can be managed using Configuration Manager. It can also discover the network infrastructure in the environment. Discovery creates a discovery data record (DDR) for each discovered object and stores this information in the Configuration Manager database.When r

mainly applied to Japan and North America, and E1 is suitable for Europe and China and other regions. 3 , ISDN protocol model:The first layer: the physical layer, which specifies the electrical and mechanical characteristics of various ISDN devices, and the physical electrical signal standards;The second layer: Data link layer, complete the physical connection between the data framing/Zhei and the corresponding error correction functions, to provide a error-free communication link to the upper

Rom and Ram refer to the semiconductor memory, ROM is the abbreviation ofRead on LY memory, RAM is the abbreviation of random Access memory. Rom can still hold data while the system is powered off, and ram usually loses data after power-down, typical RAM is the memory of the computer.There are two main types of RAM, a static RAM, which is very fast, is the fastest storage device to read and write, but it is also very expensive, so it is only used in very demanding places, such as CPU Ram/sram, l

chipset of the motherboard, you can also identify the appearance of the CPU slot on the motherboard. The socketa slots used by the AMD processor have 462 pins, which are in a large shape and have no support. The intel processor's socket478 slots have 478 pins, which are in a small shape, there is a bracket (figure) around ).　　　　2. Memory and motherboard combination:　　The importance of memory must have been heard. In fact, the memory slots are also integrated into the motherboard, and they also

The DM series of TI's digital multimedia platform integrates the arm and DSP dual-core processor: the DSP processor runs the DSP/BIOS operating system, and is responsible for audio/video coding and decoding algorithms and other graphics processing algorithms; the ARM processor runs the montavista Linux operating system, responsible for device initialization and graphical user interface management. ARM processor-end montavista Linux loading and startup requires bootloader to load the kernel from

method is effective for many CDs, but I dare not say 100% is valid. Why? Because I cannot try all the CDs! This type requires no registration code, no software, fashion choice! Method 5: Use File Monitor to handle encrypted discs with Hidden Directories The file monitor software may not be very familiar to everyone. It is a pure "green" ** software that monitors the execution status of specified files in the system. For example, you can specify which file is opened, which file is closed and wh

supports this function in Windows XP, And the hyper-threading Support Plan on Windows has been canceled. (5) application software support is required: Generally, software that supports multi-processor can support hyper-Threading Technology, but in fact there are not many such software, and they prefer graphics, video processing, and other professional software, game software is rarely supported. Application software includes Office 2000 and Office XP. In addition, later versions of Linux ke

main board's North Bridge voltage and CPU vdda voltage (PLL voltage) can increase the limit value of the outer frequency. Set the memory frequency and Nb frequency together with the multiplier.PCIe frequency: PCIe bus frequency. This option will directly affect your video card and peripheral devices. We recommend that you do not change it to reduce instability.DRAM frequency: Memory frequency (Frequency Division) setting. The Asus motherboard provides the memory frequency for real-time computin

Nowadays, the more Internet cafes open, the more fierce the competition is. Every Internet cafe administrator wants to improve the competitiveness of Internet cafes. This article will talk about the additional services required by an Internet cafe. Configurations of your Internet cafe: Switch: a real up to STAR-S2024M as the main switch, then 7 24 ports of the real up to 1824 + switch, 8 switches constitute a star network. Vro: Vigor2003.

-end bus, is the outer frequency equal to the memory frequency? The memory has evolved to DDR. Compared with the original one, the data in a clock cycle can be transferred twice as much as the original one. DDR stands for double data rate, meaning double data transmission rate. The DDR transmission speed is 266 at the 133mhz external frequency. When the external

with other DRAM types, it refers to the oldest DRAM memory, which is not optimized in addressing and is slow, it was only available on computers earlier than 386.Fpram/fastpage Ram, fast page memory, reads data in the form of pages, faster than dram, 486 used. Edoram, extended data output Ram, which is a faster reading method than the fast-page memory, widely seen in computers in the 486 and early Pentium era, the Edo RAM used on the PC is usually 72-pin on one side. Now you can find them on ol

two main categories: Static RAM (Ram/sram), SRAM is very fast, is currently read and write the fastest storage device, but it is also very expensive, so only in a demanding place to use, such as the CPU of a buffer, two-level buffer. Another known as Dynamic RAM (Ram/dram), DRAM retains data for a short time and is slower than SRAM, but it is faster than any ROM, but the price of DRAM is much cheaper than SRAM, and computer memory is DRAM. There are many types of dram, common

bandwidth has become a bottleneck in the performance of the card. Video memory bandwidth is one of the most important factors to determine graphics performance and speed. Calculation formula Video memory Bandwidth = working frequency x Memory bit width/8. When the conditions allow, the purchase of video card with large memory bandwidth as much as possible, this is a key choice. Restrictive factors Because the video memory bandwidth refers to the graphics processing chip and memo

concept of description and does not involve code.the bootloader we use in Project X projects is Uboot, and the specific code references the fourth section, "Kernel the implementation of the prepare action in Uboot" 1. Kernel image to the appropriate location of the DDR Kernel images typically exist on storage devices, such as Flash\emmc\sdcard.Therefore, the kernel image needs to be loaded into the RAM location before the CPU can access the kernel.Th

First make clear memory of three frequency, core frequency, operating frequency, equivalent frequency (also into interface frequency), usually said that the DDR2 800 of the 800 is the equivalent frequency of the memory (interface frequency), but also the most meaningful frequency, and memory bus bandwidth directly linked, such as DDR2 The 800 bandwidth algorithm is 800MHZX64/8, or 6.4gb/s. and the operating frequency is the equivalent frequency divided by 2, which applies to the DDRDDR2DDR3 (SD
