Abstract
Two banks of memory are selectively accessed from a first interface terminal and a second interface terminal through multiplexer circuitry whereby one memory bank can be read by one terminal while the other memory bank is being updated from the other interface terminal. The multiplexer circuitry is controlled by a control register which responds to an operation code whereby either memory bank can be updated while the other memory bank is being read for hardware parameters, for example.
