The history of 64-bit computing is quite rich and interesting. Companies such as Cray have started using 64-bit registers in their systems in the 70 's, but the truly pure 64-bit computations didn't really come until the 90 's. The first is the R4000 of MIPS, then the DEC Alpha processor. By the middle of the 90, both Intel and Sun had 64-bit designs. The real turning point for consumers is that AMD released a 64-bit PC processor in 2003 that is compatible with the Intel 32-bit x86 processor.

signals by using mathematical techniques to perform transformations or to extract information, which are represented by a sequence of numbers. Over the past more than 20 years, digital signal processing has been widely used in communications and other fields. ARM: ARM (Advanced RISC machines) can be thought of as a company name, or as a generic term for a class of microprocessors, or as a technology name

Some people think that Ubuntu's ARM route (supporting ARM servers) is "Gambling ". This is a bad word. Why? As we all know, CPU (CPU) is the heart of a computer, and the number of transistor particles determines its "energy consumption. However, simply pursuing the reduction of the number of transistor particles is not the fundamental solution to the problem. If there are only several hundred transistors in

ArticleDirectory Preparing the host server Qemu is well-known as a free replacement for VMware, allowing users to run a PC within a PC. what isn't so well known about qemu is that, in addition to emulating x86 ubuntures, it can emulate amd64, iSCSI, MIPS, PPC and arm CPUs. In the case of the ARM architecture, qemu provides a convenient, if slow, environment in which development can be done

matter the use, is the slot does not respond to the signal, if the QT5 signal can be bound to any slot, do not know the signal and slot parameters default value of the signal line. Qt5 's qtcreator is better than the previous, easy to debug. Other aspects have a lot of improvements, Qt5.5.0 added Qt3d and qtcanvas3d modules, but the embedded can not be used, you need to have embedded platform OpenGL. Well, that's all I can say, let's see Qt5.5.0 compile porting.My system is Ubuntu 14.04 compile

The difference between the two is that the BL command is transferred to the sub- Before the program is executed, copy the address of the next instruction to R14 (LR, link register ). Because the BL command saves the location of the next command Therefore, you can use the command "mov PC, LR" to return a subroutine. The B command cannot imp
