Abstract
Techniques are disclosed for performing a flush and restore of a history buffer (HB) in a processing unit. One technique includes identifying one or more entries of the HB to restore to a register file in the processing unit. For each of the one or more HB entries, a determination is made whether to send the HB entry to the register file via a first restore bus or via a second restore bus, different from the first restore bus, based on contents of the HB entry. Each of the one or more HB entries is then sent to the register file via one of the first restore bus or the second restore bus, based on the determination.
