FPGA-based FFT Processor Design [Date: 2008-10-23] Source: foreign electronic components by Yang Xing, Xie Zhiyuan, and Rong Li [Font:Large Medium Small] 　 1 IntroductionWith the rapid development of digital technology, digital signal processing has penetrated into various disciplines. In digital signal processing, many algorithms, such as correlation, filtering, spectral estimation, and convolution, can be implemented by converti

I. knowledge points The bean post-processor allows additional bean processing before and after the initialization callback method. The main feature of the bean postprocessor is to process all bean instances in the IOC container one by one, not just a single bean instance. In general, the bean postprocessor is used to check the validity of bean attributes or modify bean attributes according to specific conditions. The basic requirement of bean post-

Problem: There was a mismatch between the processor architecture of the project being built "msil" and the processor architecture of the reference"Your DLL name"," Amd64 ". this mismatch may cause runtime failures. please consider changing the targeted processor architecture of your project through the Configuration Manager so as to align the

There are two arm instruction sets and thumb instruction sets. The arm instruction set is 32-bit long and has the most complete functions. The thumb instruction set is 16-bit long and can implement most of the functions of the arm instruction set. Thumb instruction set is extremely highCodeDensity (reduced by 30% on average ). The ARM processor has two processor states that correspond to the two sets

Recently, Intel released three new Haswell core desktop processors, respectively, i7-4790, i5-4690 and i3-4360, using better thermal conductivity and packaging materials, so the frequency is higher, theoretical performance is stronger. At the same time, the 9 Series Chip Group also came out together, joined the SATA Express and m.2, such as fast storage technology support, the largest 16GB cache boot technology, the overall performance is more powerful. Three new Haswell Desktop

Profile: With the release of the Intel Pentium III processor, many new features have been brought to the program designers. With these new features, programmers can create better products for users. Many of the new features of Pentium III and Pentium III Xeon (Xeon processors) enable her to run faster than the Pentium II and Pentium II Xeon processors, which include a processor serial number (unique

Do you think it's just a CPU when you lift a phone processor? What, you always think so? Well, boy, it's naïve. Have you heard of the "core M" processor in the PC field? The processor, which can be plugged into a tablet, laptop or computer, is not a single processor, but is called the "Soc" (on-chip system), and the m

Mutex is a multi-processor. Program The most common collaboration method in design. We put a resource into the critical section: A single point of time can only be executed by one thread. This feature is called mutex. The standard method for implementing mutex is to use an ilock object with the following interfaces.

Contact Email: feixiaoxing @ 163.com] Before I started working in a chip company, I knew very little about the chip design. I knew a lot about the chip company datasheet. There is no such resource, and there is no such requirement. However, when I came to a new company, especially after I realized the open-source CPU, everything had changed. Open-source CPU-based code, open-source code compil

Author: Tian kaiwenDate: 2011-6-6 14:59:16PS: I will summarize it for future reference. If it is reproduced, please indicate the sourceQQ: 1324343063 Recently, we have analyzed the cpu_init.s of 6410 in uboot. This is the configuration of DDR. Because DDR is an update of SDRAM, we will first look at the SDRAM. The following is a recent summary. See: This is 64 m (32 m + 32 m), the principle of SDRAM 1. Why does the address line 2440 or 2410 start to be connected from addr2? The address line

A foreign hacker named Dmitry grberger tried to create an eight-bit simple computer micro-control device and run Linux on it. He wrote an ARM Simulator: Two hours after the startup, he saw the command line prompt (init =/bin/bash). Four hours later, he saw the Ubuntu logon page. After logging on, the system is still available to some extent. after entering a command, you can see the response within one minute. Generally, Linux does not run on systems with less than 32 bits. Therefore, grbe

The ultimate goal is to design a CPU with a sequential nature.The CPU reschedules the computing phase, moves PC computing to the fetch phase, and obtains SEQ +CPU. SEQ +:Reschedule the computing phase ---- Re-adjust the activity of the update PC phase at the beginning of a clock cycle so that it can calculate the PC value of the current command. This is the difference between SEQ and SEQ + PC computing. In SEQ +, to calculate the current PC, you need to use registers to save the signals ge

Dynamically concatenate SQL statements in the project and use union all to connect the result set. Each query statement uses in (hundreds of values ). Statement: Select aa from T1 WHERE aa IN (1, 2, 3, 4 ..............................) union allselect aa from T2 WHERE aa IN (1, 2, 3, 4 ..............................) When there are many in and union all operations, an exception occurs.The query processor has exhausted internal resources and cannot g

commands, variable instruction lengths, and multiple addressing methods. These are also the disadvantages of CISC, because they greatly increase the difficulty of decoding, however, with the current high-speed hardware development, the speed improvement caused by complex commands is far less than a waste of time on decoding. In addition to the x86 instruction sets used in the personal PC market, CISC is no longer needed for servers and larger systems. The reason why x86 still exists is to be co
