Abstract

A return stack buffers (RSB) is modified to store index values instead of addresses. When a function is called, the address following the function call is stored in a look-up table and the index at which the address is stored is pushed to the RSB. When a function returns, an index is popped from the RSB and used to identify an address in the look-up table. In another embodiment, the RSB is modified such that each entry comprises two or more address slots. When a function is called, the address following the function call is pushed to the RSB and stored in a selected one of the address slots in a top entry in the RSB. One or more pointer bits within the entry are set to indicate which slot the address was stored in.
