The General Dynamics/Veridian/Veda Systems 314-290125-300 is a PCI decommutator module that decodes individual parameters from serial PCM data streams. This PCI expansion card integrates three Altera Flex 10K programmable logic devices with an AMCC PCI Matchmaker S5935 local bus interface controller and four Cypress CY7C4275 32K x 18 deep synchronous FIFO buffers. The architecture enables real-time processing and temporary buffering of incoming PCM data before transmission to the host system.
## Technical Specifications
• Three (3) Altera Flex 10K embedded programmable logic devices (PLDs)
• One (1) AMCC PCI Matchmaker S5935 local bus interface logic chip
• Four (4) Cypress CY7C4275 32K x 18 deep synchronous FIFO buffers
• PCI Local Bus (Peripheral Component Interconnect) interface
• Standard PCI expansion card form factor
## Key Features
• Serial PCM decommutation and parameter extraction from incoming data streams
• Deep FIFO buffering for data staging before host PC transmission
• Programmable logic architecture supporting custom signal processing algorithms
• PCI interface management between FPGA and host bus
• Synchronous operation tied to single bus clock reference
## Typical Applications
• Serial PCM telemetry data processing and decoding
• Hardware-based decommutation in avionics and aerospace test systems
• Real-time data stream analysis and parameter extraction
• System upgrades and hardware transition scenarios requiring data redecommissioning
## Compatibility & Integration
Designed for integration into PCI bus architecture systems. The card operates as a standard PCI parallel bus expansion device, synchronized to the host system clock and supporting typical PCI bus signaling and timing conventions.
