Abstract
Magneti Marelli Powertrain is developing new systems in EMS and robotized gear box product ranges. To achieve the best performance and comfort during change gear phase strategies of two worlds need high integration and share of real time parameters. Figure 1 exemplifies this concept. The current link solution via serial CAN line is not enough and a higher integration with the two SWs using the same platform and RTOS tasks is required. Due to Automotive engine embedded flash architectures adopted, higher clock microprocessor is not available. This paper describes a dual-processor platform for automotive power-train control with a high-bandwidth interconnection network among processors, memory, and I/O sub-systems, which is suitable for a System-On-Chip (SOC) implementation[8]. The two processors share memory and I/O address space and can operate in parallel at full speed. The cost of this solution, in terms of gates and power dissipation, is not substantially higher than more classical architectures with a multi-master bus or multiple processor busses connected through gateways, but offers almost twice the performance.
