The phrase "a hardware level" is correct and usable in written English.
It can be used when discussing aspects related to the physical components of a computer or electronic device, particularly in contrast to software or higher-level functions.
Example: "The issue lies at a hardware level, indicating that the problem is with the physical components rather than the software."
Alternatives: "a physical level" or "a device level".
Fortunately, the ports are identical on a hardware level and a USB 3 port will work with both USB 2 and USB 3 devices and a USB 2 port will work with both USB 2 and USB 3 devices.
A hardware level solution is very sophisticated.
SPM is basically a hardware level technique and mainly focuses on the transistor and process technology.
Would the notional Evil Government try to assert its control at a hardware level, ie in the microprocessors themselves?
The DPM techniques at a hardware level can selectively turn off the idle system components or reduce the performance of the partially unexploited ones.
The current LHCb trigger system consists of a hardware level, which reduces the LHC inelastic collision rate of 30 MHz, at which the entire detector is read out.
The trigger system consists of a hardware Level-1 (L1) and a software based high-level trigger (HLT) that reduces the event rate from the design bunch-crossing rate of 40 MHz to an average recording rate of a few hundred Hz.
Oddly, his tweet goes on to confirm that this unlock works only with the 4S (and not the iPhone 4), suggesting that it relies on a hardware-level exploit that went overlooked during the 4S' creation.
The second solution, which must be implemented at a very low hardware level, uses a basic function to allow the process to emulate continuous control and therefore independent of the sampling instants.
Once you've reached flagship hardware level, a good device is a given.
It's not clear if a change at the hardware level like this would affect its production of new iPhones, or if it would have to rethink the way its next-generation phones work.
