How to enable 1.3 mpu6050 (Large End) and M4 FPU

How to enable 1.3 mpu6050 (Large End) and M4 FPU Original article. You are welcome to repost it. For reposted content, please indicate the source. The most recent time is the I2C of stm32. I know that the I2C of stm32 is not easy to use, because I have used analog I2C, and I have also written the AVR I2C, that is, the twi hardware driver, so I want to try writing stm32 hardware I2C... In order to avoid the trouble caused by the Library, the standard

From: http://blog.renren.com/blog/256814551/844695191 Floating Point operation has been a fixed point CPU problems, such as a simple 1.1 + 1.1, fixed point CPU must follow the IEEE-754 standard algorithm to complete the operation, for 8-bit single chip microcomputer has been a nightmare, for 32 single-chip microcomputer, there will not be much improvement. Although the Q-based processing of floating point numbers can give full play to the operational performance of 32-bit single-chip microcomput

Basic use of Intel x87 FPU

Intel x87 FPU is designed for scalar floating point computing. It can compute single precision Floating Point (32 bits), Double Precision Floating Point (64 bits), and extended Double Precision Floating Point (80 bits, and complies with the ieee754 standard. X87 FPU can work in 32-bit compatibility mode and 64-Bit mode. In both cases, the number of FPU data regi
