hardware circular buffer

hardware circular buffer

(programming, hardware)digital signal processors whichsupport hardware circular buffers automatically generate andincrement pointers for memory accesses which wrap to thebeginning of the buffer when its end is reached, thus savingthe time and instructions otherwise needed to ensure that theaddress pointer stays within the boundary of the buffer, andspeeding the execution of repetitive DSP algorithms.
