Asynchronous control transfer

摘要

Methods and apparatus to perform asynchronous control transfer are described. In one embodiment, upon occurrence of an event (e.g., an architectural event), a service routine data block (SRDB) is accessed via a service routine base pointer (SRDS) and a service routine offset value (SRDBP) to obtain the address of a yield service routine via a service routine instruction pointer (SRIP) and a service routine code segment (SRCS). Other embodiments are also described.
