The PMC platform is designed according to the hardware of Microsoft Windows CE and Intel Portable Multimedia Player, and its growth potential largely depends on portability, price, storage reliability and size. For example, giving up Windows and adopting Linux operating system Lindows not only expands the support platform of the product, but also does not need to pay a lot of licensing fees.

2. storage; stock

PMC allows users to access multimedia conveniently and quickly from personal computers, which is impossible without mass storage. PMC, which emphasizes portability, has special requirements for storage media, such as small floor space, large capacity, high integration, good reliability and excellent performance. At present, PMC may use two storage media, one is traditional flash memory, and the other is small hard disk.
