To make the circular buffer and circular queue accessible to STL algorithms such asfind,for_each,copy, and the like, the circular buffer implements the requiredbeginandendmember functions, returning a circular bufferIterator(seeFigure 1), which points to the beginning and end of the buffer, respe...
Circular buffering makes a good implementation strategy for aqueuethat hasfixed maximum size. Should a maximum size be adopted [被採用]for a queue, then a circular buffer is a completely ideal implementation; all queue operations are constant time. However, expanding a circular buffer requires shif...

There are mainly four operations that can be performed on a circular queue:Enqueue: Insert an element into the circular queue. Dequeue: Delete an element from the circular queue. Front: Get the front element from the circular queue. Rear: Get the last element from the circular queue....
It is used in CPU scheduling to maintain jobs in a queue and assign one of them a time to execute while the rest wait. It helps to cycle through all jobs quickly and distribute resources to each job fairly until all jobs are finished. ...
However, many algorithms are implemented in stages, with an intermediate signal being created between each stage. For instance, a recursive filter carried out as a series of biquads operates in this way. The brute force method is to store the entire length of each intermediate signal in memory...
Overview of Digital Signal Processing Algorithms Circular buffers Circular buffers are useful in DSP programming because most implementations include a loop of some sort. In the filter example, all the coefficients are processed, and then the coefficient pointer is reset when the loop is finished. Us...
The queue status is read by a transmit scheduler and updated by another process that processes enqueue and dequeue requests (often referred to as a queue manager). The timing of these operations can cause a race condition in which the transmit scheduler reads a queue status modified by the ...
The prefetch unit118may prefetch instruction code from the system memory142for storage within the instruction cache116. The prefetch unit118may employ a variety of specific code prefetching techniques and algorithms. The dispatch unit114may output operations executable by the execution core(s)134as wel...
