According to foreign media reports, Marvell has launched a series of high-end port number, ultra-low latency automotive switch chips with Gigabit routing throughput capacity. The new product portfolio includes the industry's first high port count aggregation switch chip, which can provide Gigabit performance for all ports, so as to realize data aggregation of safety critical sensors in ADAS, as well as data transmission of high-speed PCIe host uplink. Marvell's latest automotive products also include a differentiated switch chip, integrated with 100base-t1 phy and advanced routing and security features, which can be used in large gateway applications, connecting multiple domain controllers. (picture source: Marvell official website) with the increasing demand for advanced safety performance of automobiles and huge data bandwidth of networked automobiles, Ethernet has been continuously adopted by vehicle networks and has grown rapidly, while the former vehicle networks mainly used low-speed traditional connections. Marvell's single chip 88q5072 and 88q6113 switch chips can reduce BOM cost and occupy space, never meeting the growing market demand. Marvell's automotive switch chip is based on the arm ® cortex-m7 architecture, which can realize advanced protocol and security software deployment on the switch chip without using external host processor. The device can load a time sensitive network with TSN function for vehicles to support low supervision and filtering (IEEE 802.1qci) and frame estimation (IEEE 802.1qbu). The integrated L3 hardware accelerator allows multi Gigabit routing throughput to be increased to 10Gbps without internal processor intervention. These devices not only promote large-scale data transmission in the vehicle network, but also provide efficient sleep / wake-up function supporting TC10 standard (open alliance), reducing the total power consumption. With the increasing risk of network crime in automobile industry, these multi Gigabit Ethernet switch chips with high security are designed to solve this problem. Marvell's new solution provides powerful security features, including enhanced deep packet inspection (DPI) engine and trusted boot capabilities at the underlying hardware layer. "Modern vehicles are becoming data centers on wheels," said will Chu, vice president and general manager of automotive business at Marvell semiconductor. Marvell drives network innovation with advanced solutions for connectivity, computing, and storage. Our innovative switch chip portfolio enables the new generation of car zoning architecture and large backbone gateways to connect and capture large amounts of real-time data from multiple sources. "
