Claim 9:
10. A method comprising:
storing, by a fetch control circuit, given fetch parameters in a return prediction circuit, wherein the given fetch parameters correspond to previously accessed return addresses;
in response to fetching a call instruction:
retrieving particular fetch parameters from the return prediction circuit, wherein the particular fetch parameters correspond to a return address for the call instruction; and
pushing, by the fetch control circuit, the return address and the particular fetch parameters onto a return address stack circuit; and

in response to fetching a return instruction corresponding to the call instruction:
retrieving, by the fetch control circuit, the return address and the particular fetch parameters from the return address stack circuit; and
creating, by the fetch control circuit using the return address and the particular fetch parameters, a next fetch request to retrieve instructions subsequent to the return instruction.
