Detailed Description

Provides CPU architecture specific functions that can not be defined in the Base Library due to dependencies on the PAL Library

The CPU Library provides services to flush CPU TLBs and place the CPU in a sleep state. The implementation of these services on Itanium processors requires the use of PAL Calls. PAL Calls require PEI and DXE specific mechanisms to look up PAL Entry Point. As a result, these services could not be defined in the Base Library.
