摘要： A method for communication between multiple processors using registers that are accessed by four register select lines which are translated from the original system address. The address translation is performed off of the main processor board to reduce loading effects on the local bus and reduces the pin count of processor board. A signal representing which of the processors is currently active is used as a pseudo address line for the purpose of the translation. The original addresses of the I/O registers may be either input/output or memory mapped.

摘要： A clock signal is distributed over a circuit board and across a connector as a sine wave. A circuit located near the clocked circuitry converts the sine wave into a same frequency square wave for use by the clocked circuitry. The output stage of the converter circuitry provides a high output level to drive CMOS circuitry. The output transistor is pulled up to 5 volts, but the preceding transistors are pulled up to 6.3 volts so that the base to emitter drops are compensated.
