A compatibility card is an expansion card for computers that allows it to have hardware emulation with another device.

A hardware compatibility layer consists of tools that allow hardware emulation.

A compatibility layer avoids both the complexity and the speed penalty of full hardware emulation.

Hardware compatibility layers involve tools that allow hardware emulation.

Mr. Curry said that kind of hardware emulation was "the only way you can insure real compatibility."

There have been some performance optimizations (especially in the texture decoder), but generally speaking, performance decreased in favor of more accurate hardware emulation.

Data encryption and decryption and hardware emulation are software functions that might run at wire speed (or close to it) when embedded in a microchip.

Hardware virtualization is not the same as hardware emulation.

Lastly, for hardware emulation, all the relevant licenses of the software running on the system are required.

So, those systems may be thought of as System/32 with added "hardware emulation" of System/3.
