Operation
2.1 Functional Description
The CPMC-1553R is a PMC card with one or two, dual-redundant MIL-STD-1553B buses, eight user
inputs, and eight user outputs. The board interfaces to the user I/O through the PMC connector Pn4. Two
PMC connectors, Pn1 and Pn2 provide a direct connection to the PCI Bus. The Altera FLEX10
Programmable Logic Device (PLD) and the ILC-DDC Mini-ACE Device provide the interface between the
PCI bus and the MIL-STD-1553B bus. Each MIL-STD-1553B bus is implemented using an ILC-DDC
Mini-ACE device with 64kB x 16 of shared RAM. The implementation is shown in Figure 3.
