A hardware facility is described for the functional test of the analog devices floating point chip set used in the IBM RT-PC. The Analog Devices Floating Point-Chip Set test card, shown in the figure provides the necessary logic to interface between the 8-bit IBM PC bus and the ADSP (Analog Devices Signal Processor) Floating-Point Chip set. The ADSP chip set consists of the ADSP 3221 Floating-Point Arithmetic Logic Unit, the ADSP 3210 Floating Point Multiplier, and the ADSP 1401 microcode sequencer. These chips are used on the AFPA (Advanced Floating-Point Accelerator) in the RT-PC. The card allows all data and control inputs to the ADSP chip set to be software controllable.
