Circular Buffer or Circular Buffer Implementation in C Friends welcome to this video series on Embedded System. It should be efficient, easy on the eyes, generically typed. The only requirement for implementing a circular buffer is a method to keep a pointer’s value within the range of the buffer and wrap around from the highest to lowest address (or vice-versa). Should a maximum size be adopted for a queue, then a circular buffer is a completely ideal implementation; all queue operations are constant time.

BTW, doing this in C++ on Linux. Simple implementation of a circular buffer in C#. For now it need not be MT-capable. The Concept of Circular Buffer A circular buffer is an array of constant length, and we use it to store data in a continuous loop. Features include configurable buffer size, optional overwrite mode, and comprehensive error handling. Embedded software often involves state machines, circular buffers and queues. e First In First Out. Summary A digital signal processor is a specialized microprocessor for the kind of algorithms employed in DSP. Feb 24, 2024 · Why would I use a circular buffer in my coding projects? How do I implement a circular buffer in my code? What are some common operations performed on a circular buffer? Are there any pitfalls to avoid when working with circular buffers? Can I dynamically resize a circular buffer? Circular Buffer This is a simple implementation of a circular buffer, built in C and executed as a console application. Nov 14, 2025 · This guide walks you through implementing a robust circular buffer in C, covering array management, read/write pointers, and handling overflow conditions. Jun 3, 2025 · Circular Buffer Mode When cache_seqlens is provided to update operations, the convolution state operates as a circular buffer, enabling memory-efficient processing of long sequences. Sep 4, 2025 · A high-performance, thread-safe circular buffer (ring buffer) implementation in C that provides FIFO data storage with fixed memory allocation. This means the circular_buffer is not fully thread-safe. GitHub Gist: instantly share code, notes, and snippets. cu 76-94 Kernel Traits and Template Specialization Trait Structure Design Each kernel family uses traits structures to define compile-time constants and type information: 5 days ago · I often reach for a circular queue when I want predictable memory usage and constant-time operations without the overhead of dynamic allocations. In this article, we will learn how to implement a circular buffer in C++ using vector. You can also find some coding tips to implement circular buffers in software in Appendix B of this book. As a regular queue with circular fashion, circular buffers can be implemented using fixed-size arrays or circular linked list. Aug 31, 2021 · Circular Buffer or Ring Buffer is a circular queue that allows the usage of memory in a contiguous manner. Mar 18, 2024 · In this tutorial, we’ll learn the concept of a circular buffer in engineering and computer science. The useful property of circular buffer is that it doesn’t need to have its elements shuffled around when an element is produced/ consumed. About Generic circular buffer implementation for Go with rotational velocidensity effect countermeasures. Circular Buffer in C++. With your current approach, you need to keep one element less in your buffer to know the difference between full and empty. This is a single file implementation, which means that you only need to copy the CircularBuffer. Ring Buffer Ring Buffer (or Circular Buffer) is a bounded circular data structure that is used for buffering data between two or more threads. More than 150 million people use GitHub to discover, fork, and contribute to over 420 million projects. Nov 13, 2017 · To read more about the Analog Device’s hardware circular buffer, please see section 3. How It Works A Ring Buffer is implemented using a fixed-size array that wraps around at the boundaries. We will only cover the array implementation, in C++ and Python. You'll gain a reusable, high-performance component for your C projects. Jul 23, 2025 · A circular buffer, also known as a cyclic buffer or ring buffer, is a data structure that uses a single, fixed-size buffer as if it were connected end-to-end. It is implemented using a fixed-size array and two pointers: a read pointer and a write pointer. Jun 3, 2025 · Circular Buffer Implementation The circular buffer mode optimizes memory usage for long sequences by reusing a fixed-size state buffer: Sources: csrc/causal_conv1d_update. This implementation showcases the core operations of a circular buffer: enqueue (add an item), dequeue (remove an item), and peek (view the next item without removing it). We’re going to be using an array of integers for this guide. Think about a printer spool, a network packet buffer, or a fixed-size telemetry log: data arrives, data leaves, and you want the buffer to keep moving in a loop instead of shifting elements. Understanding Circular Buffers A circular buffer is a fixed-size buffer that wraps around itself, allowing continuous writing and reading of data. I expect following operations: ability to provide size of the buffer when creating I want a simple class that implements a fixed-size circular buffer. […] Please subscribe my channel TechvedasLearn for latest update. However, expanding a circular buffer requires shifting memory, which is comparatively costly. This article will give you an overview of the data structure and walks you through the steps involved in implementing circular buffers in low memory devices. A robust, thread-safe circular buffer implementation in C, designed for embedded systems with UART/USART communication. You should analyze various algorithms presented at the Wikipedia page for Circular buffer, i. As we keep writing to a ring buffer, it wraps around as it reaches the end. I expect following operations: ability to provide size of the buffer when creating Measuring power-of-2 buffers ¶ Calculation of the occupancy or the remaining capacity of an arbitrarily sized circular buffer would normally be a slow operation, requiring the use of a modulus (divide) instruction. Jun 27, 2020 · 2. To instantiate a circular buffer, we just declare an object and specify the templated type for our buffer. Circular Buffer follows the FIFO principle i. Feb 12, 2019 · A circular buffer is a data structure that uses a fixed-size buffer as if it were connected end-to-end (in a circle). Now two questions: Is circular lock-free buffer the answer? If so, before i roll my own, do you know any public implementation that will fit my need? Any pointers in implementing a circular lock-free buffer are always welcome. e. It allows the user to write values to the buffer and read values from the buffer.
