VIPER Microprocessor
VIPER is a 32-bit microprocessor design created by Royal Signals and Radar Establishment (RSRE) in the 1980s, intended to be used in safety-critical systems such as avionics Avionics (a blend word, blend of ''aviation'' and ''electronics'') are the Electronics, electronic systems used on aircraft. Avionic systems include communications, Air navigation, navigation, the display and management of multiple systems, .... It was the first commercial microprocessor design to be formally proven correct, although there was some controversy surrounding this claim and the definition of proof. The design was completed in 1987 and implemented initially by RSRE in a gate array. Marconi Electronics subsequently licensed the design, implementing it as the MAS1908 VIPER-1, fabricated using CMOS and silicon-on-sapphire technologies, being packaged as a 120-pin grid array product. Architecturally, VIPER is a 32-bit processor supporting 20-bit word-oriented addressing of memory and of "I/O s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microprocessor
A microprocessor is a computer processor where the data processing logic and control is included on a single integrated circuit, or a small number of integrated circuits. The microprocessor contains the arithmetic, logic, and control circuitry required to perform the functions of a computer's central processing unit. The integrated circuit is capable of interpreting and executing program instructions and performing arithmetic operations. The microprocessor is a multipurpose, clock-driven, register-based, digital integrated circuit that accepts binary data as input, processes it according to instructions stored in its memory, and provides results (also in binary form) as output. Microprocessors contain both combinational logic and sequential digital logic, and operate on numbers and symbols represented in the binary number system. The integration of a whole CPU onto a single or a few integrated circuits using Very-Large-Scale Integration (VLSI) greatly reduced the cost of ...
