Key Features

Direct Memory Access (DMA) engine handles single transactions up to 64 MB without processor intervention

Hardware-based flow control prevents data loss at receiver with fixed-frame data insertion

Integrated interrupt controller reports link failure, transaction completion, and buffer status

Byte/word swapping on DMA and register paths provides system flexibility

Multi-level error detection and status reporting

Support for front and rear I/O configurations

Point-to-point topology support

Typical Applications

Real-time radar and sonar signal processing

Medical imaging systems with high-speed data streaming

Video production and acquisition pipelines

Sensor array processing requiring low-latency DSP interconnect

High-throughput telemetry and data logging

Compatibility & Integration The SL240 integrates into existing PCI and CompactPCI-based systems via PCIe or XMC form factors. Its specialized sFPDP protocol optimization eliminates traditional overhead associated with general-purpose network stacks, delivering deterministic, low-latency performance essential for time-critical applications.
