A faster version can be found in the C language implementation of FFT and IFFT source code, which does not depend on a specific platform. The porting is very simple, does not rely on other libraries, and allows customization of the number of points. The algorithm is derived from the usage instructions of the FFT … Read more
1 Problem On the beach, there is a pile of peaches, and five monkeys come to share them. The first monkey divides the pile into five equal parts, but there is one left over. This monkey throws the extra one into the sea and takes one part. The second monkey divides the remaining peaches into … Read more

In the translated article from Slow to SIMD, a SourceGraph engineer discusses one optimization technique known as Bounds Check Elimination (BCE), and poses a question to the readers: “ Why use a[i:i+4:i+4] instead of a[i:i+4]? The first part of this article answers this question. The second part introduces a better method for bounds check elimination. … Read more
Single Instruction Multiple Data (<span>SIMD</span>) is a parallel computing technology that allows a single instruction to process multiple data points simultaneously. SIMD is widely used in modern CPUs and can significantly enhance the performance of compute-intensive tasks such as image processing, machine learning, and scientific computing. As the application of the Go language in high-performance … Read more

The JLink tool is an essential artifact for microcontroller development, including a hardware emulator (with different versions: EDU/BASE/PLUS/WIFI/ULTRA+/PRO) and driver software for PC (frequently … Read more
In Go language web development, choosing the right routing library is crucial. Chi and HttpRouter are both lightweight routing solutions favored by developers, each with its own characteristics suitable for different scenarios.Among them, Chi is a feature-rich modular router built on the standard library net/http, known for its modular design and strong middleware support. It … Read more
Today, we will delve into the two “permutation wizards” in the C++ standard library— the next_permutation and prev_permutation functions. They are like gymnasts in the world of numbers, elegantly transforming sequences into all possible permutations! 🎯 Function Usage Instructions 📋 Function Signatures // Default comparison using <bool next_permutation(BidirectionalIterator first, BidirectionalIterator last);bool prev_permutation(BidirectionalIterator first, BidirectionalIterator last);// … Read more
