Gen 4 PCIe switches enable autonomous driving ecosystem
High-speed, low-latency connectivity for distributed, heterogenous compute systems are a fundamental element in next-generation autonomous driving applications. To address this need, Microchip Technology has announced the market’s first Gen 4 automotive-qualified PCIe switches. These Switchtec™ PFX, PSX, and PAX switches provide cutting-edge compute interconnect capabilities for Advanced Driver-Assistance Systems (ADAS).
For example, the Switchtec PFX Gen 4 PCIe switch family comprises high-reliability PCIe switches supporting up to 100 lanes, 52 ports, 26 virtual switch partitions, 48 non-transparent bridges (NTBs), hot- and surprise-plug controllers for each port, advanced error containment and comprehensive diagnostics and debug capabilities, a wide breadth of I/O interfaces and an integrated MIPS processor.
“Our automotive-qualified portfolio of Switchtec Gen 4 switches provides the lowest latency and high bandwidth required to link the CPU and accelerator building blocks used in ADAS applications,” says Krishna Mallampati, Associate Director of Marketing and Applications for Microchip’s data center business unit.
Switchtec Gen 4 PCIe switches provide the high-speed interconnect that supports distributed, real-time safety-critical data processing in ADAS architectures. PCIe is emerging as the preferred compute interconnect solution for the automotive industry for the same reasons it has become pervasive in the data center market. It provides ultra-low latency and low-power bandwidth scalability to CPUs and specialized accelerator devices.
“The qualification of Microchip’s solutions to meet the stringent needs of the automotive market is a significant milestone, and one NVIDIA closely collaborated on,” said Michael Truog, senior director of Automotive Platform Architecture at NVIDIA. “Microchip’s automotive PCIe switches deliver flexibility and advanced programmability, enabling high-speed SoC and GPU connectivity within our NVIDIA DRIVE platform.”
Microchip’s ChipLink diagnostic Graphical User Interface (GUI) provides extensive debug, diagnostics, configuration and forensics tools for rapid deployment.
Switchtec automotive-qualified Gen 4 PCIe switches are available in production.
