Computation of cyclic redundancy checks may use whichever form is more convenient. Parallel update for a byte or a word at a time can also be done explicitly, without a table. This is normally used in high-speed hardware implementations. For each bit an equation is solved after 8 bits have been shifted in. The following tables list the equations for some commonly used polynomials, using following symbols: As the CRC-32 polynomial has a large number of terms, when computing the remainder a byte at a time each bit depends on several bits of the previous iteration. In byte-parallel hardware implementations this calls for either multiple-input
Interactive computing by collaborations of more than 40 faculties. The Tangible Media Group of MIT, led by Professor Hiroshi Ishii, explores the Tangible Bits & Radical Atoms visions to seamlessly couple the dual world of bits and atoms by giving dynamic physical form to digital information and computation. Interactive computing In computer science, interactive computing refers to software which accepts input from humans as it runs. Interactive software includes most popular programs, such as word processors or spreadsheet applications. By comparison, noninteractive programs operate without human contact; examples of these include compilers and batch processing applications. Interactive computing focuses on real-time interaction
