100Gbps class in-vehicle Ethernet Switch architecture for next generation autonomous driving car
SessionLeading edge digital IP
DescriptionCurrent vehicle systems need to process the amount of data from a wide variety of sensors, such as radars and cameras, at high speed and in real time, therefore Ethernet Switch embedded in vehicle system should communicate at a high throughput of 50Gbps. In addition, the next generation vehicle system which autonomous driving technology becomes increasingly sophisticated, high speed communication of 100 Gbps will be required. Furthermore, in-vehicle ECUs are required to consume even less power in order to prevent heat generation in the in-vehicle environment and optimize battery efficiency.
Conventionally, Ethernet Switch have used HASH method for search processing in the switch processing block, which has low power consumption but limited throughput. TCAM method is essential in order to achieve high throughput of 100 Gbps, but it has a problem of high power consumption. Additionally, architectural optimization in the searching processing block is also required to achieve high throughput with low power consumption.
We have realized an Ethernet Switch that can achieve high throughput with low power consumption by adopting a pipeline search method and a phase shift search method on TCAM base. This Ethernet Switch fulfills the requirements of next generation autonomous driving car.
