Concept designer Gabriele Patrizi in continuum mode as inspiration, designed for WIN10 mobile phone surface flat type Expansion dock, named "Lumia Tutto", The docking dock provides Win10 tablet or Win10 notebook experience for WINDOWS10 handsets. Lumia Tutto is designed to match the Lumia940, in Gabriele's vision, Lumia940 will be powered by Intel Atom X7 chip, with 2K resolution screen, supplemented by 4GB memory and 128GB fuselage storage space, Th

code has a number of test digits, 8-bit, 16-bit, 32-bit, and so on, the same principle. The 16-bit CRC code produces the rule is to send the binary sequence number left 16 bits (that is, multiplied by 2 of 16 times), divided by a polynomial, the final remainder is the CRC code.CRC code for the use of the Model 2 algorithm, that is, the polynomial division with no borrow subtraction operation, the operation is equivalent to XOR or operation. This should be carefully understood, is the basis of p
