    REMOTE TERMINAL (RT) ARCHITECTURE
    The Enhanced Mini-ACE/-ACE's RT architecture builds upon
    that of the ACE and Mini-ACE. The Enhanced Mini-ACE/-ACE
    provides multiprotocol support, with full compliance to all of the
    commonly used data bus standards, including MIL-STD-1553A,
    MIL-STD-1553B Notice 2, STANAG 3838, General Dynamics
    16PP303, and McAirA3818, A5232, and A5690. For the
    Enhanced Mini-ACE/-ACE RT mode, there is programmable
    flexibility enabling the RT to be configured to fulfill any set of sys-
    tem requirements. This includes the capability to meet the MIL-
    STD-1553A response time requirement of 2 to 5 s, and multiple
    options for mode code subaddresses, mode codes, RT status
    word, and RT BIT word.
    The Enhanced Mini-ACE/-ACE RT protocol design implements
    all of the MIL-STD-1553B message formats and dual redundant
    mode codes. The design has passed validation testing for MIL-
    STD-1553B compliance. The Enhanced Mini-ACE/-ACE RT per-
    forms comprehensive error checking including word and format
    validation, and checks for various RT-to-RT transfer errors. One of
    the main features of the Enhanced Mini-ACE/-ACE RT is its
    choice of memory management options. These include single
    buffering by subaddress, double buffering for individual receive
    subaddresses, circular buffering by individual subaddresses, and
    global circular buffering for multiple (or all) subaddresses.
    Other features of the Enhanced Mini-ACE/-ACE RT include a
    set of interrupt conditions, a flexible status queue with filtering
    based on valid and/or invalid messages, flexible command ille-
    galization, programmable busy by subaddress, multiple options
    on time tagging, and an "auto-boot" feature which allows the RT
    to initialize as an online RT with the busy bit set following power
    turn-on.
    RT MEMORY ORGANIZATION
    TABLE 38 illustrates a typical memory map for an Enhanced Mini-
    ACE/-ACE RT with 4K RAM. The two Stack Pointers reside in
    fixed locations in the shared RAM address space: address 0100
    (hex) for the Area A Stack Pointer and address 0104 for the Area
    B Stack Pointer. In addition to the Stack Pointer, there are sever-
    al other areas of the shared RAM address space that are desig-
    nated as fixed locations (all shown in bold). These are for the
    Area A and Area B lookup tables, the illegalization lookup table,
    the busy lookup table, and the mode code data tables.
    The RT lookup tables (reference TABLE 39) provide a mecha-
    nism for allocating data blocks for individual transmit, receive, or
    broadcast subaddresses. The RT lookup tables include subad-
    dress control words as well as the individual data block pointers.
    If command illegalization is used, address range 0300-03FF is
    used for command illegalizing. The descriptor stack RAM area, as
    well as the individual data blocks, may be located in any of the
    non-fixed areas in the shared RAM address space.
    Note that in TABLE 38, there is no area allocated for "Stack B".
    This is shown for purpose of simplicity of illustration. Also, note
    that in TABLE 38, the allocated area for the RT command stack is
    256 words. However, larger stack sizes are possible. That is, the
    RT command stack size may be programmed for 256 words (64
    messages), 512, 1024, or 2048 words (512 messages) by means
    of bits 14 and 13 of Configuration Register 3.
