The L3 Harris FPP523-64 Field Programmable Processor 4 (FPP4) Module is the System 550's
third-generation real-time programmable processor. It produces
over twice the throughput in half the space as the previous
generation processor. The FPP4 uses a standard off-the-shelf 350
MHz Power PC 6U VME single board computer (SBC) to achieve its
unprecedented performance of over 3 million basic algorithms per
second. The use of Motorola COTS SBCs provides a ready
upgrade path to emerging technologies. The SBC is connected to
the System 550's high-speed processing bus, the MUXbus, via a
3U+ interface module that supports original FPP3 MUXbus
mezzanines. In addition, two PCI Mezzanine Cards (PMCs) can be
added to the SBC for special applications. Adding FPP4s achieves
a linear increase in system performance thanks to the System 550's
data flow architecture.
The FPP4 dramatically enhances the System 550's algorithm
capabilities. Not only does the FPP4 increase the performance of
such basic algorithms as "average over n" and "fifth order EU
conversions," it further boosts the performance of large grain
algorithms (e.g., signal analysis, secondary PCM decommutation,
etc.). For maximum flexibility, the user can use, concatenate, or modify
algorithms from L-3's extensive libraries to create, simulate, test, and
debug algorithms in the C high-level language or in assembler on
the System 550's color graphics workstations.
The 49072121-1 L3 Harris FPP4 MUXbus Interface Board may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
Functions
Digital interface board that provides bidirectional communication between MUXbus architecture and external systems. Implements protocol conversion, signal conditioning, and data routing for avionics bus integration. Features multiple channel I/O ports, programmable data rates, built-in error detection/correction, and hardware-level message filtering. Supports MIL-STD-1553 and ARINC protocols with real-time data transfer capabilities. Includes onboard memory buffers, timing synchronization circuits, and diagnostic monitoring. Commonly deployed in military aircraft systems, flight control computers, and mission systems requiring reliable multiplex bus connectivity for critical data exchange between subsystems.
Platforms
The FPP4 MUXbus Interface Board is designed for embedded systems, operating on a VMEbus backplane. It provides MIL-STD-1553B and ARINC 429 communication interfaces. The board facilitates data transfer and control functions within aerospace and defense applications, integrating with host processors via the VMEbus and connecting to external devices through its bus interfaces.
Applications
Provides multiplexed data bus interfacing capabilities for avionics and mission systems integration. Enables bidirectional communication between disparate subsystems using standardized MUXbus protocols. Supports high-speed serial data transfer, protocol conversion, and signal conditioning. Interfaces with flight management computers, navigation systems, weapons control units, and sensor packages. Common applications include military aircraft avionics integration, unmanned aerial vehicle control systems, electronic warfare platforms, and ground-based command and control stations. Used in retrofit programs for legacy aircraft modernization and new platform development requiring robust data distribution architectures.
Accessories
Requires FPP4 MUXbus backplane or compatible chassis for installation; interfaces include MUXbus edge connector for board insertion. Connectors: 1) A micro-miniature or custom MUXbus connector interfacing with backplane signals; 2) standard I/O connectors defined by the system using the MUXbus interface. No separate external connectors or standalone interface cables are typical; operation depends on integration within the MUXbus framework. No additional specific accessories documented.
Interfaces
MUXbus Interface Board designed with a MUXbus connector interface (specific pin count not detailed). Typically mounts into a compatible backplane or chassis supporting MUXbus architecture for signal multiplexing and data transfer. Intended to interface with other modules via MUXbus standard connectors. Detailed references indicate operational control and monitoring via standard industrial connectors consistent with L3Harris board designs, but specific connectors and pin counts for this model are not explicitly documented in the provided data.
Specifications
Integrates MUXbus communication protocol within electronic systems, designed for defense and aerospace applications; employs printed circuit board hardware. Connects via electrical connectors to other avionics equipment for data transmission and interfacing. Commonly used in military aircraft systems for signal processing, data management, and communications interfacing. Supports multi-channel data handling and real-time data processing, ensuring secure and reliable communications between various subsystems.
