Advantages in Fusion, Migration, & Scalability

HRU-201U can not only be perfectly served as a feature rich and extended temperature DSRC V2X on-board unit, also provides high application flexibility to enable “V2X and Sensor Fusion applications, Today.” on its unique modular-structured architecture:

A. V2X Fusion
  • Enables V2X on DSRC sub-system to offload the processing power demand of the main system through RMII connection.
  • Enables V2X Fusion application on Linux with truly scalable Freescale® i.MX 6 CPU and u-blox® GNSS module with feature rich I/O ports.
  • Client-server system architecture provides a smooth software migration path to enable V2X on variable Linux main system, no impact on existing Linux software.
  • Enables V2X RF or wireless communication solution through on-board PCIe or I/O connectivity.
B. Software Architecture and Migration Path
Client-server dual- processor/system architecture enables flexible V2X system selection on Linux OS or ThreadX RTOS.It provides a smooth software migration path on existing software core competence.
C. Hardware Scalability
Truly scalable key components to achieve high flexibility to speed up V2X innovations.
  • Freescale® i.MX 6 DualLite scales to Dual or Quad core CPU.
  • u-blox® NEO-7P upgrades to NEO-M8L or M8U.
  • Removes un-needed 3G, GNSS, and HSM module or lowers DRAM/NAND Memory.
  • Enables LTE and Wi-Fi/Bluetooth (DHXA-222) wireless communication or 3rd party V2X RF through on-board PCIe or I/O ports.
