Number | Title | Inventor(s) | Notes |
---|---|---|---|
4,176,258 | Method and circuit for checking integrated circuit chips |
|
Describes Functional Redundancy Checking (FRC), used not only in the iAPX-432, but also in some i960 and Pentium family processors. |
4,287,570 | Multiple bit read-only memory cell and its sense amplifier |
|
Best known for use in the 8087 floating point co-processor, but was also used in the 43203. Note similarity to NCR patent 4,192,014 and Motorola patent 4,272,830 . |
4,315,308 | Interface between a microprocessor chip and peripheral subsystems |
|
Describes the ACD "packet bus" used between 432 processors and the Bus Interface Unit. |
4,315,310 | Input/Output Data Processing System |
|
Describes the 43203 Interfface Processor (IP). |
4,325,120 | Data Processing System |
|
Describes the General Data Processor (GDP) and the Input/Output Processor (IOP). Note that the IOP is not the same as the Interface Processor (IP), and that the IOP never shipped as a product. |
