Frequently Asked Questions
What graphics capabilities does the 2K2000 provide?
The Loongson 2K2000 includes an integrated 2D/3D graphics engine supporting modern display requirements. The graphics subsystem supports OpenGL ES 2.0 for 3D acceleration and provides hardware-accelerated 2D operations including blitting and composition. Maximum display resolution is 1920x1200 at 60Hz through HDMI or LVDS interfaces. The graphics engine can decode common video formats in hardware, reducing CPU load for multimedia applications. Multiple display outputs are supported for dual-screen configurations. Performance is suitable for industrial HMI, digital signage, and basic gaming applications. For comparison, the graphics performance is adequate for modern Linux desktop environments and browser-based applications with smooth scrolling and transitions.
Evaluate graphics requirements against 2K2000 capabilities. Suitable for HMI and signage applications requiring moderate graphics performance.
Can the 2K2000 support dual independent displays?
Yes, the Loongson 2K2000 supports dual independent display outputs, making it ideal for HMI applications requiring separate operator and public displays. The processor provides both HDMI and LVDS interfaces that can operate simultaneously with independent content. Each display can have different resolutions and refresh rates up to 1920x1200. The graphics driver supports extended desktop mode allowing applications to span both displays or run independently. Hardware cursor support is available on both outputs. For industrial panel PC applications, this enables local operator interface plus external monitor output. The dual display capability is fully supported in Linux with standard X11 or Wayland display servers.
Leverage dual display capability for HMI applications. We can provide reference designs for dual-screen panel PC implementations.
What PCIe devices can be connected to the 2K2000?
The Loongson 2K2000 provides a PCIe 2.0 x4 interface that can be configured as single x4, dual x2, or quad x1 lanes. This flexibility allows connecting various PCIe devices including additional Ethernet controllers for multi-port networking, WiFi and cellular modules for wireless connectivity, SATA controllers for additional storage, USB 3.0 controllers for enhanced USB connectivity, and FPGA modules for custom I/O expansion. The PCIe interface supports standard Linux drivers for most devices. For GPU expansion, the x4 interface can accommodate entry-level graphics cards for enhanced display capabilities. Reference designs demonstrate typical PCIe expansion configurations for network appliances and industrial controllers.
