Recent observations on firmware have highlighted a few CPU hardware bugs. One instance involves Intel's CPUs reporting misspelled names, such as "GenuineIotel" instead of "GenuineIntel." The Core i5-1245U also exhibits a missing character in its brand string. While these errors are embarrassing, they don't impact the functionality of the processors.

Another bug involves the IT81202, an embedded processor from ITE Tech. This RISC-V CPU has a pipeline flaw where instructions following a multiply instruction may fail. The workaround is to disable multiplication and division instructions. This allows for customized library functions to provide integer multiply/divide operations, mitigating the bug's impact.

Intel's misspellings likely stem from human error during design or firmware integration. The IT81202's pipeline bug is a consequence of the complexities inherent in building pipelined CPUs, particularly in the earlier days of RISC-V implementation. These observations serve as a reminder of the need for thorough testing.

These findings reiterate the importance of quality control in hardware manufacturing. While the impact of these specific bugs might be limited, they underscore the potential for errors in complex systems. It's a reminder for developers and manufacturers alike to remain vigilant in their testing and validation processes.
