Viewing data in a circular buffer in real-time - Stack Overflow

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. This structure lends itself easily to buffering data streams. There were early circular buffer implementations in hardware. WebYou may get “sequence buffer overflow” (also known as “circular buffer overflow”) errors during acquisitions, especially at high frame rates. If so, try increasing the sequence buffer size (for fast streaming of large images, much larger settings can sometimes be useful). how to stop being cold

A single-producer, single-consumer lock-free queue for C++

WebFeb 2, 2016 · Keep two different tail pointers in your buffer, one for each consumer. When the producer is updating the queue, use the farthest tail pointer (the tail pointer which is lagging behind) to check if the buffer is full. Consumers can use their own tail pointers to check if the buffer is empty. WebMay 17, 2024 · Circular buffers (also known as ring buffers) are fixed-size buffers that work as if the memory is contiguous & circular in nature.

How To Implement A Simple Circular Buffer In C - Medium

Webcircular buffer would normally be a slow operation, requiring the use of a modulus (divide) instruction. However, if the buffer is of a power-of-2 size, then a much quicker bitwise-AND instruction can be used instead. Linux provides a set of macros for handling power-of-2 circular buffers. can be made use of by: #include WebSep 12, 2002 · Circular Buffers are use for data transfer between two processes. The Producer process places items into the Circular Buffer and the Consumer process removes them. The variable capacity of the Circular Buffer accommodates timing differences between the Producer and Consumer processes.

WebAug 7, 2013 · The ring buffer (also known as a circular buffer, circular queue, or cyclic buffer) is a circular software queue. This queue has a first-in-first-out (FIFO) data characteristic. These buffers are quite common and are found in many embedded systems. WebAug 17, 2024 · Create mempool (s) to share buffers among threads/processes. Each mempool supports just a fixed size buffer, so you might want to create few mempools to match your needs. Create one MPMC ring or a set of SPSC ring pairs between your threads/processes. The SPSC solution might be faster, but it might not fit your design.
