The FP11-F Floating-Point Processor is the hardware floating point option for the KD11-Z CPU of the PDP-11/44. It implements the full FP11 floating point; it consists of a single hex card (the M7093), which plugs into a dedicated slot in the CPU's backplane.
The CPU and the FPP interact over two tri-state data paths, one for data, and another for the microcode PC. The CPU and FPP each have their own microcode PROMs; 48 bits wide in the FPP, and 56 bits wide in the CPU, for a total of 104 bits.
