One of the new salient features of the PCI Enhanced Mini-ACE is its Enhanced
Bus Controller architecture. The Enhanced BC’s highly autonomous message
sequence control engine provides a means for offloading the host processor for
implementing multi-frame message scheduling, message retry schemes, data
double buffering, and asynchronous message insertion. For the purpose of
performing messaging to the host processor, the Enhanced BC mode includes a
General Purpose Queue, along with user-defined interrupts.
The PCI Enhanced Mini-ACE RT offers the same choices of single, double, and
circular buffering for individual subaddresses as ACE, Mini-ACE(Plus), and
Enhanced Mini-ACE. New enhancements to the RT architecture include a global
circular buffering option for multiple (or all) receive subaddresses, a 50% rollover
interrupt for circular buffers, an interrupt status queue for logging up to 32
interrupt events, and an option to automatically initialize to RT mode with the
Busy bit set. The interrupt status queue and 50% rollover interrupt features are
also included as improvements to the PCI Enhanced Mini-ACE’s Monitor
architecture.
The PCI Enhanced Mini-ACE series terminals operate over the full military
temperature range of -55 to +125°C. Available screened to MIL-PRF-38534C,
the terminals are ideal for military and industrial processor-to-1553 applications.
TRANSCEIVERS
The transceivers in the PCI Enhanced Mini-ACE series terminals are fully
monolithic, requiring only a +5V power input.
The transmitters are voltage
sources, which provide improved line driving capability over current sources. This
serves to improve performance on long buses with many taps. The transmitters
also offer an option which satisfies the MIL-STD-1760 requirement for a
minimum of 20 volts peak-to-peak, transformer coupled output.
Besides eliminating the demand for an additional power supply, the use of a
+5V-only transceiver requires the use of a step-up, rather than a step-down,
isolation transformer.
This provides the advantage of higher terminal input
impedance than is possible for a 15 volt or 12 volt transmitter. As a result, there
is a greater margin for the input impedance test, mandated for the 1553
validation test.
This characteristic allows for longer cable lengths between a
system connector and the isolation transformers of an embedded 1553 terminal.
To provide compatibility to McAir specs, the PCI Enhanced Mini-ACE is available
with an option for transmitters with increased rise and fall times.
Additionally, for MIL-STD-1760 applications, the PCI Enhanced Mini-ACE
provides an option for a minimum stub voltage level of 20 volts peak-to-peak,
transformer coupled.
