Fixed size ring buffer
WebI want a simple class that implements a fixed-size circular buffer. It should be efficient, easy on the eyes, generically typed. For now it need not be MT-capable. I can always add a lock later, it won't be high-concurrency in any case. Methods should be: .Add () and I guess .List (), where I retrieve all the entries. WebJun 8, 2024 · The existing solutions, e.g. [1,2,3,4,5,6], implement ring buffer approach, but in most cases they are intended to work with fixed size data, also called messages. The solutions have also other restrictions e.g. number of ring buffer elements must be a power of 2 [5, 6]. It simplifies the data management part and makes possible to optimize the ...

WebApr 11, 2024 · 7. I found myself in need of a fixed size queue and decided to implement one using a ring (cyclic) buffer. I have tried my best to match the API of std::queue with the addition of full () to test if the queue is full and unable to accept another element. The code compiles cleanly with: -Wall -Wextra -pedantic --std=c++14 -lgtest -lgtest_main ...

Perhaps the most common version of the circular buffer uses 8-bit bytes as elements. Some implementations of the circular buffer use fixed-length elements that are bigger than 8-bit bytes—16-bit integers for audio buffers, 53-byte ATM cells for telecom buffers, etc. Each item is contiguous and has the correct data … See more In computer science, a circular buffer, circular queue, cyclic buffer or ring buffer is a data structure that uses a single, fixed-size buffer as if it were connected end-to-end.
