activated page. After waiting for the TRP time, you can expand the next operation. There are two types of write operations: burstable write and non-burstable write. The burst length is the same as the read operation. 7. OthersSometimes we see that some data lines are switched over on the schematic diagram. In fact, this doesn't matter. The reverse connection is written into the reverse interface, but the reverse interface is read, there is no reverse attack twice. Extended to the

by other aspects, such as memory, PCI-E slot, Hard drive transmission rate and so on, so the performance will also enhance a lot. Clock cycle and working frequency This is a very important performance metric, which refers to the time it takes to process a data memory. The faster the video memory speed, the unit time to Exchange data volume is also greater, in the same situation, the performance of the graphics card will be significantly improved, memory clock cycle in general NS (nanosecond)

is "Discover and correct error", It is more advanced than parity correction technology mainly because it can not only detect errors, but also to correct these errors, these errors after the computer can correctly perform the following tasks, to ensure the normal operation of the server. It's not a memory model, it's because it's not a technology that affects memory structure and storage speed, it can be applied to different types of memory, as we mentioned in the previous "parity correction" me

In the process of DDR development, it has always been to increase the data prefetch value as the main performance improvement means. But in the DDR4 era, the increase in data prefetching became more difficult, so the bank group design was introduced. What is the bank group structure like? Specifically, each bank group can read and wri

1. Basics 1.1 CPU address space Local address map is the 36bit address space that core can access. This address space includes the address space that each function module can access, the ddr sdram space, and the CCSR address space. How does the CPU core access various functional modules on the SOC? For example, elbc controller, DDR controller, and PCI Controller. It is configured through the Law (local acce

What is the relationship between technologies supported by the motherboard and CPU? CPUs of different specifications need different technical support from the main board: Super thread technology is available in intel. Although most CPUs do not support this technology, many Main Boards still use this technology; in terms of memory, there is a dual-channel

It is a pure "green" Free Software that monitors the running status of specified files in the system, such as specifying which File is opened and which File is closed, the file to which data is read. It allows you to monitor a monitored file for any operations such as reading, writing, and opening other files, and provides complete report information. Haha, you must have thought of it? Yes!

, the CPU consists of the memory, controller, register, and high-speed cache.Connection data, control, and status bus composition, CPU has become the core component that determines the computer performanceMemory, also known as internal memory or random memory (RAM), is divided into two types: DDR memory and SDRAM memory. Because sdram's capacity is low, the storage speed is slow, and the stability is poor, it has been replaced by

, the AP can also share the work of the BSP controller and complete the self-test of the memory, which can be done to maximize the parallel system self-test and device scan initialization. This assumes that before the system initialization takes time t, the system has n processors, and after parallelization, the initialization time can be reduced to t/n. Many optimizations can also be made at this stage:First, the controller parameters are re-trained only in the case of memory layout and serial

FB-DIMM memory performanceProcessor, Io, and memory are three key factors that affect the performance of a platform. On a balanced platform, the performance of these three aspects should be matched with each other, and they should not be too prominent or too "lame". This is the central idea of Amdahl's law.In recent years, the rapid development of CPU technology, in addition to the rapid increase in clock speed, also by adding hyper-threading technology, multi-core technology, etc. to improve th

X-loader is the primary boot loader. It is loaded through ROM boot loader into the internal RAM.X-loader is responsiblefor initializing the external memory and loading the u-boot from the selected boot device. X-loader supports boot from NAND, MMC/SD and Onenand. The generated x-loader.bin needs to is signed before it can be used by the ROM bootloader.
