Multirate circular buffer and method of operating the same

摘要

A circular buffer for use in a telecommunications system is described as well as a method of operating the same in which data is protected during wraparound procedures. In the operation of the circular buffer at least four reference values are stored to enable address calculations: a first reference value representative of a begin address of the circular buffer; a second reference value representative of an end address of the circular buffer; a third reference value representative of a current write address of the circular buffer; and a fourth reference value representative of a current read address of the circular buffer. The cyclic state of the buffer is also monitored in order to protect the data after a wraparound or when the buffer is full. The buffer is able to accommodate multirate data arrival.
