A method of performing link stack operations comprises the steps of reading and writing to a link stack. During a write, a location in the link stack pointed to by a current write pointer is selected and a link address associated with an instruction and a current read pointer to the link stack are written into the selected location. After the write operation, the read pointer is updated such that the new read pointer equals the current write pointer and the write pointer is updated. During a read from the link stack, a location in the link stack is selected using a current read pointer. A new read pointer and a link address associated with an instruction are read from the selected read location. |
