sets.
The TS68040 floating-point instructions, a commonly used subset of the TS68882
instruction set, are implemented in hardware. The remaining unimplemented instruc-
tions are less frequently used and are efficiently emulated in software, maintaining
compatibility with the TS68881/TS68882 floating-point coprocessors.
The TS68040 instruction set includes MOVE16, a new user instruction that allows high-
speed transfers of 16-byte blocks between external devices such as memory to memory
or coprocessor to memory.
