Computer architecture bit width From Wikipedia, the free encyclopedia
In computer architecture, 60-bit integers, memory addresses, or other data units are those that are 60 bits wide. Also, 60-bit central processing unit (CPU) and arithmetic logic unit (ALU) architectures are those that are based on registers, address buses, or data buses of that size.
A 60-bit word is typically used for high-precision floating-point calculations; it can also store 10 6-bit characters.[1]
The only widely-used computers with 60-bit words were produced by Control Data Corporation (CDC),[2] including the CDC 6000 series,[3] the CDC 7600, and the CDC Cyber 70 and 170 series.[4] Though the addressable unit was the 60-bit word, instructions were either 15 or 30 bits.[3]
Early design documents for the IBM 7030 Stretch tentatively specified its word length as 60 bits; the final design used 64.[5]
Museum examples of 60-bit CDC machines exist. There also exists an emulator for the series which will simulate the CDC 60-bit machines on commodity hardware and operating systems.[4]
