MMX
none
The EMMS instruction is used to clear the MMX state following the execution of a
block of code using MMX instructions. Because the MMX registers and tag words are
shared with the floating-point unit, it is necessary to clear the state before executing
code that includes floating-point instructions.

Description
The emulate MMX instruction bit (EM) of the control register (CR0) is set to 1.
Save the floating-point or MMX state if the task switch bit (TS) of the con-
trol register (CR0) is set to 1.
An exception is pending due to the floating-point execution unit.
