most CPUs currently support floating-point unit FPU,FPU as a separate coprocessor placed outside the processor core, but for embedded processors, floating-point operations are inherently less used, and some embedded processors remove the floating-point coprocessor.X86 processors generally have the FPU. And the ARM PPC MIPS processor will appear without the

VLC player is an excellent open source player that can play MPEG-1, MPEG-2, MPEG-4, DivX, DVD/VCD, digital satellite channels, digital earth TV channel (Digital terrestial television channels) play online videos through IPv4 and IPv6 networks on many job platforms. This software development project was initiated by French students. Participants came from all over the world and designed multi-platform support for playing network streaming and local mul

assembly instructions for floating-point numbers. The 32-bit generated code is FLD/FMUL/FSTP, and the 64-bit command is used under movss/mulss/movsd/. Look down, it seems this thing is related to the platform. We continue our investigation, and we find that the FLD/FMUL/FSTP, and so on, are made by the FPU floating-point operator, and, exactly, the FPU x87 instruction, where the

Armel and ARMHF differences What is ARMHF In Ubuntu 12.04 and Debian, in addition to arm, Armel, there is a version called ARMHF. What this thing is. As is known to all, Armel is currently the main arm ABI. ARMHF is a variant of the Armel, the main difference is in floating-point computation. In Armel, there are three conventions on floating-point calculation. In the case of GCC, the corresponding-mfloat-abi parameter values are three: Soft,softfp,hard. Soft means all floating-point operations a

TCC, short for tiny C compiler (http://bellard.org/tcc/), is a special C compiler, you can use it as a C language interpreter, you can also embed your own application into a dynamic code generator. Yes, that's what we do. In our project, the motion rules of the particle system are described in C language, and then the native code is dynamically generated by TCC to run. In this way, both efficiency and high dynamic capability are maintained. However, since a third-party library is used, it is ne

ARM v5te devices. Floating-point operations with this goal use software floating-point arithmetic. Binary code created with this ABI will be available to run on all arm devices. armeabi-v7a: Create a library that supports ARM V7 devices and use the hardware FPU instructions (float Point Unit, float unit). x86: Generates binary code to support IA-32 instruction sets that contain hardware-based floating-point operations.

For a variety of reasons, such as low power consumption and encapsulation limitations, some of the previous ARM architecture processors are expensive to add to floating-point units because of their internal resources , because of the need for additional software implementations. With the development of technology, the current high-end ARM processor has the ability to perform floating-point operations . This difference between the old and new architectures results in two different embedded applic
