x87 is a floating-point-related subset of the x86 architecture instruction set. It originated as an extension of the 8086 instruction set in the form of optional floating-point coprocessors that work

…dedicated floating-point registers, while some, like Intel x86, go as far as independent clocking schemes. CORDIC routines have been implemented in Intel x87 coprocessors (8087, 80287, 80387) up to the 80486 microprocessor series, as well as in the Motorola 68881 and 68882 for some kinds of floating-point…
