  • Auxiliary control signal decode using high performance address lines
    Patent number: 5423021
    Abstract: An apparatus that develops the M16* control signal, which indicates a 16 bit memory device is responding, from the latched address LA<> lines to provide a faster response time than if it were decoded from the SA<> address lines. Decode values for specific 8 kbyte blocks in a 128 kbyte address range are stored. The particular value for an 8 kbyte block is multiplexed and provided to the M16* line based on the decode of the LA address lines.

  • Daisy-chained serial shift register for determining configuration of removable circuit boards in a computer system
    Patent number: 5287531
    Abstract: An apparatus for determining system configuration in a computer system using only one 8 bit data port. Permanent connections on each of the microprocessor and memory boards provide respective configuration and/or memory information about each board. The signals are stored in serial out shift registers associated with each board that are daisy chained together. These shift registers serially transmit the configuration information to one 8 bit data port, which then transmits this information to the computer system in 8 bit increments. If a given slot is empty it is automatically bypassed in the shift register daisy chain.
