Programming Example 5.2 A Circular Buffer in C Once we build a circular buffer, we can use it in a variety of ways. We will use an array as the buffer: #define CMAX 6 /* filter order */ int circ[CMAX]; /* circular buffer */ int pos; /* position of current sample */ The vari...
ring buffer / circular buffer 又名环形队列 / 环形缓冲区,其通过开辟固定尺寸的内存来实现反复复用同一块内存的目的。由于预先开辟了固定尺寸的内容,所以当数据满的时候,可以有两种处理方式,具体使用哪一种按照实际需求,具体如下: 1)当队列满的时候,新来的数据会覆盖最古老的数据,这种数据结构的特点是数据的写入...

Another example where circular buffers are useful is when working with individual inputs and only saving the last N inputs. A circular buffer can be written so that when the end of the allocated input buffer is reached, the pointer automatically wraps around to the beginning of the buffer. ...
Differences from previous example /* This approach replaces the CircularBuffer 'end' field with the 'count' field and changes these functions: */ void cbInit(CircularBuffer *cb, int size) { cb->size = size; cb->start = 0; cb->count = 0; cb->elems = (ElemType *)calloc(cb->size...
