In this paper, we put forward an innovation method of high-speed and real-time error diffusion, which is based on Floyd-Steinberg algorithm. The design introduces LUT(look up table) and pipeline technology instead of complex multiplication operations, which accesses to the memory frequently. The whole design uses Verilog HDL language to program and Quartus ii 8.0 to synthesize and layout. At the end of the paper, we use a 48 pixel as an example, then simulate and verify it on the Modesim, which can prove the correctness of the design. Compared with the standard Floyed-Steinberg algorithm, this design can reduce the computation complexity, use a smaller memory space to exchange lots of logic units and increase the throughput of the algorithm. Besides, it has the advantages of good reconfigurability, simple hardware structure and high real-time.

The transportation industry is facing major challenges that come along with innovative trends like autonomous driving. Due to the growing amount of network participants, smart sensors, and mixed-critical data, scalability and interoperability have become key factors of cost-efficient vehicle engineering. One solution to overcome these challenges is the AUTOSAR Adaptive software platform. Its service-oriented communication methodology allows a standardized data exchange that is not bound to a specific middleware protocol. OPC UA is a communication standard that is well-established in modern industrial automation. In addition to its Client–Server communication pattern, the newly released Publish–Subscribe (PubSub) architecture promotes scalability. PubSub is designed to work in conjunction with Time-Sensitive Networking (TSN), a collection of standards that add real-time aspects to standard Ethernet networks. TSN allows services with different requirements to share a single physical network. In this paper, we specify an integration approach of AUTOSAR Adaptive, OPC UA, and TSN. It combines the benefits of these three technologies to provide deterministic high-speed communication. Our main contribution is the architecture for the binding between Adaptive Platform and OPC UA. With a prototypical implementation, we prove that a combination of OPC UA Client–Server and PubSub qualifies as a middleware solution for service-oriented communication in AUTOSAR.
