virtual page specified in rAX and the
ASID specified in ECX.
Alternate notation for move from CR8 to
register.
Alternate notation for move register to
CR8.
Alternate notation for move from CR8 to
register.
Alternate notation for move register to
CR8.
Secure initialization and jump, with
attestation.
Set Global Interrupt Flag.
A.6.5 64-Bit Media Instruction Reference
These instructions described in this section operate on data located in the 64-bit MMX
registers. Most of the instructions operate in parallel on sets of packed elements called
vectors, although some operate on scalars. The instructions define both integer and
floating-point operations, and include the legacy MMX instructions and the AMD
extensions to the MMX instruction set.
Converts packed double-precision
floating-point values in an XMM
register or 128-bit memory location to
packed doubleword integers values in
the destination MMX™ register.
Converts two packed doubleword integer
values in a MMX™ register or 64-bit
memory location to two packed double-
precision floating-point values in the
destination XMM register.
Converts packed doubleword integer
values in a MMX™ register or 64-bit
memory location to single-precision
floating-point values in the
destination XMM register.
A.6.6 3DNow!™ Instruction Set
This chapter describes the 3DNow! Instruction Set that the simulator supports and
simulates. 3DNow! Technology is a group of new instructions that opens the traditional
processing bottlenecks for floating-point-intensive and multimedia applications.
Fast Enter/Exit of the MMX or
floating-point state.
