Abstract
In an embodiment, a processor may be configured to fetch N instruction bytes from an instruction cache (a 'fetch group'), even if the fetch group crosses a cache line boundary. A branch predictor may be configured to produce branch predictions for up to M branches in the fetch group, where M is a maximum number of branches that may be included in the fetch group. In an embodiment, branch prediction values from multiple entries in each table may be read and respective branch prediction values may be combined to form branch predictions for up to M branches in the fetch group.
