微处理器(MCU)是ECU中的关键组件。使用传统的汽车MCU不可能达到SIL3认证要求。因此需要采用全新的芯片架构,以确保处理结果、总线流量的数据完整性以及存储器中数据的安全性与可靠性,同时满足严格的响应时间要求。开发人员可充分利用市场上的微处理器,为ECU制动控制功能达到SIL3认证标准提供所需技术。TI与罗伯特·博世有限公司联合开发的TMS570就是这样一款MCU。
Microprocessors (MCUs) are a key component in ECUs. With traditional automotive MCUs it is not possible to meet SIL3 certification requirements. Therefore, a new chip architecture is needed to ensure processing results, data integrity of bus traffic, and data security and reliability in memory while meeting stringent response time requirements. Developers can take full advantage of microprocessors available on the market to provide the required technology for ECU brake control to meet SIL3 certification standards. TI and Robert Bosch Co., Ltd. jointly developed TMS570 is such an MCU.
