    40MX and 42MX FPGA Families
    v6.0
    1-3
    A42MX24 and A42MX36 devices contain D-modules,
    which are arranged around the periphery of the device.
    D-modules contain wide-decode circuitry, providing a
    fast, wide-input AND function similar to that found in
    CPLD architectures (
    Figure 1-4
    ). The D-module allows
    A42MX24 and A42MX36 devices to perform wide-
    decode functions at speeds comparable to CPLDs and
    PALs. The output of the D-module has a programmable
    inverter for active HIGH or LOW assertion. The D-module
    output is hardwired to an output pin, and can also be
    fed back into the array to be incorporated into other
    logic.
    Dual-Port SRAM Modules
    The A42MX36 device contains dual-port SRAM modules
    that
    have
    been
    optimized
    asynchronous applications. The SRAM modules are
    arranged in 256-bit blocks that can be configured as 32x8
    or 64x4. SRAM modules can be cascaded together to
    form memory spaces of user-definable width and depth.
    A block diagram of the A42MX36 dual-port SRAM block
    is shown in
    Figure 1-5
    .
    The A42MX36 SRAM modules are true dual-port
    structures containing independent read and write ports.
    Each SRAM module contains six bits of read and write
    addressing (RDAD[5:0] and WRAD[5:0], respectively) for
    64x4-bit blocks. When configured in byte mode, the
    for
    synchronous
    or
    highest order address bits (RDAD5 and WRAD5) are not
    used. The read and write ports of the SRAM block
    contain independent clocks (RCLK and WCLK) with
    programmable polarities offering active HIGH or LOW
    implementation. The SRAM block contains eight data
    inputs (WD[7:0]), and eight outputs (RD[7:0]), which are
    connected to segmented vertical routing tracks.
    The A42MX36 dual-port SRAM blocks provide an optimal
    solution for high-speed buffered applications requiring
    FIFO and LIFO queues. The ACTgen Macro Builder within
    Actel's Designer software provides capability to quickly
    design memory functions with the SRAM blocks. Unused
    SRAM blocks can be used to implement registers for
    other user logic within the design.
