Storage Method of floating point and floating point in memory, floating point First, let's talk about how to convert decimal places to binary decimal places. The computer doesn't even know the decimal data. He only knows 0 and 1. So, decimal decimal

This paper is derived from quantization, data type, overflow and underflow, and the floating-point number is considered as a quantization method of real field, and the difference between floating-point number, especially irregular floating-point

One: Floating-point simulators on early arm: Early arm does not have a coprocessor, so floating-point operations are simulated by the CPU, where floating-point operations are performed on floating-point arithmetic simulators (float math emulation),

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

  First, let's look at a piece of code (in VC, in C ++ ): int a = 2; int b = 3; int c = 6; if(1.0 / a + 1.0 / 3 + 1.0 / c >= 1.0) cout Is yes output or no output?Answer:In the console, after several seconds, no is output.The problem arises.

Linux kernel supports floating point operations.Currently, most CPUs support the floating point operation unit FPU. FPU is placed out of the core of the processor as a separate coprocessor. However, for embedded processors, floating point operations

Although almost every processor andProgramming LanguageAll support floating point operations, but mostProgramStaff seldom pay attention to it. This is easy to understand-most of us seldom need non-integer types. In addition to scientific computing

At present, the parallel optimization of the CNN convolutional neural network on the hardware platform is studied, and the relevant knowledge needs to be mended. Transferred from: http://www.cnblogs.com/kevinq/p/4480563.html Reference: 1.http://www.
