PROCESSOR AND MEMORY INTERFACE
The ACE terminals provide much flexibility for interfacing to a
host processor and optional external memory. FIGURE 1 shows
that there are 14 control signals, 6 of which are dual purpose, for
the processor/memory interface. FIGURES 9 through 14 illus-
trate six of the configurations that may be used for interfacing a
BU-65170 or BU-61580 to a host processor bus. The various
possible configurations serve to reduce to an absolute minimum
the amount of glue logic required to interface to 8-, 16-, and
32-bit processor buses. Also included are features to facilitate
interfacing to processors that do not have a “wait state” type of
handshake acknowledgement. Finally, the ACE supports a reli-
able interface to an external dual port RAM. This type of interface
minimizes the portion of the available processor bandwidth
required to access the 1553 RAM.
The 16-bit buffered mode (FIGURE 9) is the most common con-
figuration used. It provides a direct, shared RAM interface to a
16-bit or 32-bit microprocessor. In this mode, the ACE's internal
address and data buffers provide the necessary isolation
between the host processor's address and data buses and the
corresponding internal memory buses. In the buffered mode, the
1553 shared RAM address space limit is the BU-65170/61580's
4K words of internal RAM. The 16-bit buffered mode provides a
pair of pin-programmable options:
