ring buffer c

C code is used to implement some common data structures, such as list, map, tree, string function, and ring buffer. It is worth looking at people who learn C language. The boost Library also has the implementation of a circular buffer. The specific example is as follows: [Cpp]# Include Int main (int/* argc */, char */* argv */[]) {// Create a circular

SQL Server Ring Buffer--relationship between SQL Server and ring bufferThe SQL Server operating system (SQLOS) is responsible for managing SQL Server-specific operating system resources. One of the related dynamic management attempts sys.dm_os_ring_buffers will be identified as informational only. No support is provided. No future compatibility is guaranteed.Firs

In the project, threads need to share a buffer FIFO queue, one thread adds data to the queue, and the other thread obtains data (typical producer-consumer problem ). We started to consider using STL vector containers without random access. Frequent deletion of the first element causes memory movement, reducing efficiency. If you use linklist as a queue, you also need to allocate and release node memory frequently. Therefore, you can implement a limite

The implementation of ring buffer Bufferc language The problem of too many Message Queuing lock calls is solved, and the other annoying thing is probably too much memory allocation and release operations. The frequent memory allocation not only increases the overhead of the system, but also makes the memory fragmentation increasing, which is very unfavorable to the long-term stable operation of our server.

Serial Ring Buffer experiment Introduction to 1.1 experiment The simplest method of serial port data processing is that the data is received and sent back in the same mechanism: successfully received a number, triggered into an interrupt, read the data in the interrupt function, and then immediately. This kind of data processing mechanism is "non-buffered interrupt mode", although this data processing me

This article is very long. But in order for you to connect to the context for reading, I decided to write them into a blog. TheKey PointsYes: do not overlap the ring; notify consumers; batch processing at the producer end; and how multiple producers work to

1. PrefaceA ring buffer was used in the recent project, and the code was changed by the Kfifo of the Linux kernel. Buffers are often used in the file system to alleviate the CPU's read and write memory and the speed of reading and writing disks through buffers. For example, when a process a produces data to another process B, process B needs to process the data passed on by processes and writes to the file,

Recently we open-source Lmax disruptor, which is the key to making our transaction process so fast. Why open source? Because we are aware that there is something wrong with the traditional perception of high-performance programming. We have found a better and faster way to share data between threads. If we don't share it with everyone, it's too selfish. Furthermore

Precautions for using lock-free queue (ring buffer), queue Loops The circular buffer is a common data structure in the producer and consumer models. The producer puts the data into the end of the array, and the consumer removes the data from the other end of the array. when the end of the array is reached, the producer returns to the header of the array. If there

One is the Mid-Autumn Festival advantage activity, and the other is the completion of many things .. Finally, the NRF communication was completed, and improved ring buffering and simple communication protocol planning were used. There are quite a few things to do, and the actual workload is not small .. Hah

The concept of cyclic buffer (ring buffer), in fact from the Linux kernel (Maybe), provides a lock-free method for solving competition problems in some special situations. This particular situation is when the producer and the consumer have only one, and in other cases it must be locked. Corresponds to the definition of it in the Linux kernel: struct Kfifo {
