The data transfer instructions move floating-point, integer, and BCD values between memory and the floating point registers. Table 3-13 Data Transfer x86 processors did not use a separate floating point coprocessor; floating point functions were easily distinguishable from 8086 instructions. liest designs of the 8086 – the 80x87 FPU (floating point unit or math coprocessor). Normal algebraic rules apply only to infinte precision arithmetic. When the 8086 CPU first appeared in the late 1970s, semiconductor technology was not to the point where Intel could put floating point instructions directly 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 Other instructions are FPU-specific Floating point is like scientific notation. 3.15576ten ? 109 IEEE 754 single precision: 32-bit floating point.The floating-point control register (FPCR) contains status and control information. It controls the arithmetic rounding mode of instructions that specify The first solution we will consider is with the 8086. It was already designed and in production, so it was decided to build a co-processor (also called a
