The communication between CPU and IOP may take different forms depending on the particular computer considered. The sequence of operations during CPU and IOP communication is shown in figure.

  • The CPU sends a test I/O instruction to IOP to test the IOP path.
  • The responds by inserting a status word in memory location.

· The CPU refers to the status word in memory. If everything is in order, the CPU sends the start I/O instruction to start the I/O transfer.

  • The IOP accesses memory for IOP program.

· The CPU can now continue with another program while the IOP is busy with the program. Both programs refer to memory by means of DMA transfer.

  • When the IOP terminates the execution of its program, it sends an interrupt request to the CPU.
  • The CPU then issues a read I/O instruction to read the status from the IOP.
  • The IOP transfers the status word to memory location.

· The status word indicates whether the transfer has been completed satisfactorily or if any error has occurred during the transfer.

What does mmHG mean relating to the eye?

In the context of the eye, mmHg refers to millimeters of mercury, and it is a unit of measurement for intraocular pressure (IOP). IOP is the fluid pressure inside the eye, and measuring it in mmHg helps to assess the risk of conditions like glaucoma.


What is the purpose of a goniotomy?

to clear the obstruction to aqueous outflow from the eye, which in turn lowers the intraocular pressure (IOP).


What is the success rate of goniotomy?

Goniotomy is successful in about 94% of patients with primary congenital glaucoma in decreasing IOP, corneal haze, and corneal diameter.


Why can't people with glaucoma have LASIK?

Patients with glaucoma should not have LASIK because the intraocular pressure (IOP) of the eye is raised during the procedure.


What is the meaning of IOP in instrumentation?

Well, hello there! IOP stands for "Input/Output Port" in instrumentation. It's like a doorway that lets information come in and go out of a device, kind of like how birds fly in and out of a birdhouse. Just remember, every little detail in instrumentation has its own special purpose, just like every color on our palette adds beauty to a painting.
