Test process 1 of FFT operation using FPU + DSP library of iisf4, stm32f4fpu Test environment: Microcontroller: STM32F407ZGT6 IDE: keil5.255.0.0 Firmware Library version: STM32F4xx_DSP_StdPeriph_Lib_V1.4.0 Part 1: UseSource code fileUse the void arm_cfft_radix4_f32 (const arm_cfft_radix4_instance_f32 * S, float32_t * pSrc) function to perform the FFT operation. Prepare an empty project, configure the Keil environment, and enable

If you only know the concept of CPU, then it is impossible to understand the CPU topology. In fact, in the NUMA architecture, the concept of CPU is from big to small: Node, Socket, Core, Logical Processor. With the development of multicore technology, we encapsulate multiple CPUs together, a package commonly referred to as a socket. Where the physical processor is plugged in, it looks like this: Each core

signed arithmetic operation is either too large or too small to fit into the destination? Overflow. 9. Which flag is set when an arithmetic or logical operation generates a negative result? Sign. 10. Which part of the CPU performs floating-point arighmetic? Floating-point unit. 11. How many bits long are the FPU data registers? How many BITs is the length of the data register of a floating point operation unit? 80bits. 12. Which intel

Java uses the annotation processor to generate code-Part 2: annotation Processor This article is part 2 of my "using annotation processors to generate code for Java" series. In the first part (please read here), we will introduce Java annotations and several common methods. Now, in the second section, we will introduce annotation processors. This includes how to create annotation processors and how to r

I will upload my new book "self-writing processor" (not published yet). Today is the tenth article. I try to write it every Thursday. This chapter describes how to implement the openmips processor for teaching. This chapter provides a blueprint for the openmips System for the tutorial version. First, it introduces the design objectives of the system. It details the 5-level pipelines implemented by the ope

The annotations in Java are a magical thing that you don't know yet. You can see the custom annotations (Annotation) for the next hour. Now a lot of Android libraries are implemented using annotations, such as butterknife, we do not want to learn, we learn the note processor, we try to write a simple similar to the butterknife of things to bind the control.What is an annotation processor? The annotation

Java thread exception processor, Java thread processor Thread. UncaughtExceptionHandler is a static internal interface of the Thread class. This interface has only one method: Void uncaughtException (Thread t, Throwable e), where t represents the Thread with an exception and the exception thrown by the e-table. If an unhandled exception is thrown during thread execution, the corresponding unhandled exceptio

Small series found that recently a lot of enthusiastic netizens in the network asked a more representative question: about E3 and i5 processor which is good? E3 and i5 which is good i5 compared with E3 processor In the current high-end mainstream installed, the most choice is i5 and E3 processor, which i5 and e3-1230 price difference is not much, bu

In the second lesson example, the first processor mapper and processor adapter are configured in Springmvc.xml, as shown below. configuration of the first processor mapper beannameurlhandlermapping - Beanclass= "Org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping">Bean> Configure the first p
