C 环形缓冲的实现: 音频采集后续小实验后续小实验RING/CIRCULAR BUFFER 附送源码 圆形缓冲区(circular buffer),循环缓冲区(cyclic buffer),环形缓冲区(ring buffer),是一种用于表示一个固定尺寸、头尾相连的缓冲区的数据结构,适合缓存实时数据流。 环形缓存放置在20041到20048这8个连续的存储位置。图A示来自输入的8...
/// Returns 0 on success, -1 if buffer is full int circular_buf_put2(cbuf_handle_t cbuf, uint8_t data); /// Retrieve a value from the buffer /// Returns 0 on success, -1 if the buffer is empty int circular_buf_get(cbuf_handle_t cbuf, uint8_t * data); /// Returns true...
//User provides structvoidcircular_buf_init(circular_buf_t* cbuf, uint8_t*buffer, size_t size);//Return a structcircular_buf_t circular_buf_init(uint8_t* buffer, size_t size) 创建容器之后,我们需要填充数据并在其上调用 reset 函数。在 init 返回之前,我们要确保缓冲区容器是在空状态下创建的...
1)head index 只能指向未被写入的位置。 A‘head’ index - the point at which the producer inserts items into the buffer. 2)tail index 可以指向任何位置。 A‘tail’ index - the point at which the consumer finds the next item in the buffer. 3)队列满:当 head index 前进一个 单位后等于 ta...
面下这个网址有 RingBuffer的C代码实现, 实际上是一个C的源开库liblcthw 里实现的。 http://c.learncodethehardway.org/book/ex44.html 源开库 liblcthw的网址为https:///zedshaw/liblcthw,用C代码实现了一些用常的数据结构,list,map,tree,字符串函数,ring buffer等,习学C语言的人值得看看。

Methods are proposed herein to perform rate matching for polar codes via circular buffering of the polar encoded bits. Embodiments are directed to methods of operation of a transmitting node in a wireless system including performing polar encoding of a set of information bits in accordance with a ...
Here is the code to set up a circular buffer: ; setup coefficient circular buffer AMOV #a0, XCDP ; coefficient data pointer MOV #a0, BSAC ; starting address of circular buffer MOV #16, BKC ; size of circular buffer MOV #0, CDP ; starting offset for circular buffer BSET CDPLC ; ...
When capturing in Circular mode, PIX stores the capture data in a fixed sized buffer on disk. When the buffer is full, the oldest capture data is aged out to make room for newer data. Because the amount of space needed to store capture data is fixed, Circular captures can be run contin...
