BI-DIRECTIONAL COPYING OF REGISTER CONTENT INTO SHADOW REGISTERS

摘要

Embodiments of the present disclosure describe a processor, which may include copy circuitry coupled to a shadow register file and a control register. The copy circuitry may be configured to copy content from a range of a number of registers to a shadow range of the shadow register file in a forward or backward direction. The forward or backward direction may be based at least in part on a value stored in the control register.
