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.

Earlier this month, AMD released the desktop seventh generation Apu, code-named Bristol Ridge, the first to bring AM4 new interface, support DDR44 memory, USB 3.1, and finally can be with the Intel six-generation processor a higher. AMD Seven generation a12-9800 APU processor One of the first high-end APU models is a12-9800, Quad core 3.8-4.2ghz,radeon R7 GPU 512 stream processors, thermal de

The NAND boot steps:The Sector Media boot steps:(Sector Media devices include SD, SDHC, MMC and Movinand)1.A2S/A2M 硬件启动程序boot-strap在片上ROM。2.boot-strapper初始化sector media devices(上电启动配置选中的设备)3.boot-strapper从sector media中读取DRAM配置，初始化DDR2控制器及DRAM设备。4.boot-strapper从sector media 的 sector1读取配置，并加载boot-loader到DRAM，最后将PC置到boot-loader。5.boot-loader初始化MMU及分页表。6.boot-loader从sector media主分区中读取 RTOS/APP raw image至DRAM，并解压的最终地址（DRAM）。7.boot-loader从sector media的DSP分区中 读取并解压 DSP微程序。8.boot-lodaer跳入 RTOS/APP 代码并完成

Intel on the other side of the launch of the seventh Daicouri KABYLAKE,AMD side of the seventh generation Apu Bristol Ridge release, as early as this month, AMD low-key released a new generation of APU, but the domestic as if not released, and the novel Apu can not find any traces , it is estimated that the garage is not finished, and AMD intends to promote only in the OEM, DIY market may not be. Nevertheless, we can find the relevant evaluation of the new APU from the Overseas evaluation websit

AMD a12-9800 Performance Test Judging from the score of the test. A12-9800 's single-threaded performance increased by 6%, multi-threaded performance increased by 15%, and bandwidth increased by 50%. Basically now the excavator structure is already the limit, want to advance the performance still want to see Zen architecture. After

I received a phone interview with lousis today. To tell the truth, although I was not asked for it at the end, I had a lot to gain. After all, it was ANBA, Niu. Embedded Software Engineer requires too much knowledge, hard, soft, and network. Some

Data Data extraction Theoretically relational database, data is in the form of relationship. Usually we can see them as a collection. In this way, the data is generally in the form of disorder. The benefits of this approach are not to be discussed, but we have to admit that sometimes this can also bring us some trouble. I've had this thing lately. I met an old classmate of mine on the internet and he raised such a question. There is a table (assuming it is called mytable), and there are three

The following describes the network properties when connecting to the VMnet1, VMnet8, VMnet0 virtual switches."description" (1) after VMware Workstation 6.0, the new "team" feature was added, and the team Virtual Switch was added to the team. Virtual machines in the team can use virtual switches in the team, in addition to virtual switches such as VMnet0, VMnet1, VMnet8, and so on.(2) VMware Workstation (or VMware Server), in additi
