Industrial Control Platform Solution

Loongson 2K1000/2K2000 processors can achieve sub-millisecond interrupt response times with proper real-time Linux configuration using PREEMPT_RT patches. Typical jitter is under 50 microseconds for well-tuned systems. Hard real-time requirements can be met using RT-Thread or SylixOS real-time operating systems. The dual-core architecture allows dedicating one core to real-time tasks while running non-critical processes on the second core. Actual performance depends on system configuration, driver optimization, and workload characteristics. We recommend benchmarking with your specific control loop requirements.

For critical real-time applications, plan for kernel tuning and performance validation. Contact our FAE team for real-time configuration guidance.

Migrating industrial control software to Loongson involves several steps. First, assess software dependencies and identify any x86-specific code or assembly. Second, recompile C/C++ code using Loongson GCC or LLVM toolchain - most code compiles without modification. Third, port any real-time OS or middleware to LoongArch - RT-Thread and SylixOS have native support. Fourth, validate industrial protocol stacks - Modbus, CANopen, and EtherCAT stacks are available for Loongson. Fifth, test and optimize performance - some tuning may be needed for optimal real-time response. Our FAE team provides migration support and can review your software architecture.

Start with software assessment and compile testing. Leverage our migration support services for complex applications.

Loongson industrial platforms support comprehensive industrial communication protocols. Fieldbus protocols include CAN 2.0B, CANopen, Modbus RTU/ASCII via UART interfaces. Industrial Ethernet protocols include Modbus TCP, EtherNet/IP, Profinet, and EtherCAT (with appropriate controllers). The dual Gigabit Ethernet interfaces support standard TCP/IP and UDP protocols. Real-time Ethernet extensions such as TSN can be implemented for deterministic communication. Protocol stacks are available through open-source projects and commercial vendors. For specific protocol requirements, we can provide compatibility verification and implementation guidance.

Verify specific protocol requirements with our technical team. Most common industrial protocols are well-supported on Loongson platforms.

Loongson industrial platforms can be used in safety-related applications with appropriate system design. The processors include ECC memory support for data integrity and hardware watchdog timers for fail-safe operation. For SIL-rated applications, additional external safety controllers are typically used in conjunction with the main processor. The long-term availability commitment supports safety system lifecycle requirements. Documentation and traceability are available for safety certification processes. For specific safety requirements, engage with our technical team early in the design phase to ensure all requirements can be met.

Development timeline for a custom Loongson-based industrial controller typically ranges from 6 to 12 months depending on complexity. Phase 1 (1-2 months): Requirements analysis and architecture design using evaluation boards. Phase 2 (2-3 months): Custom hardware design based on reference schematics. Phase 3 (2-3 months): PCB layout, fabrication, and bring-up. Phase 4 (2-3 months): Software development, BSP customization, and application integration. Phase 5 (1-2 months): Testing, validation, and certification. Using reference designs and engaging FAE support can accelerate the timeline. For time-critical projects, consider starting with evaluation boards for parallel software development.
