HCMOS Enhanced Floating-Point Coprocessor

Motorola 68882 (MC68882) is an enhanced version of 68881 Floating Point Unit. The 68882 is pin- and object-code compatible with the 68881, and, like the 68881, it could work with Motorola 68020 and 68030 microprocessors. The architecture of the 68882 FPU is similar to the 68881. The FPU has 8 directly-addressable 80-bit registers. It supports seven data types: 8-bit, 16-bit and 32-bit integers, single, double and extended-precision floating point numbers, and packed decimal strings. The 68882 always converts external operands into internal extended-precision format, and performs all calculations in this format. The MC68882 has the same instruction set as the 68881 co-processor.
