An in-depth report on the automotive chip industry Altera

Being able to drive involves human-computer interaction, visual processing, intelligent decision-making, etc. the core is AI algorithm and chip. With the acceleration of automotive electronics, the growth of automotive semiconductors accelerated. In 2017, the global market scale was US $28.8 billion (+ 26%), which was much higher than the growth rate of vehicle sales (+ 3%), of which the functional chip MCU (US $6.6 billion, accounting for 23%), followed by power semiconductors (21%) and sensors (13%).

Automotive semiconductors can be divided into functional chips MCU (microcontroller unit), power semiconductors (IGBT, MOSFET, etc.), sensors and others. According to strategy analytics, among traditional fuel vehicles, the value of MCU accounts for the highest, accounting for 23%; In pure electric vehicles, MCU accounts for 11%, which is second only to power semiconductor. DIGITIMES predicts that the market scale of functional chip MCU is expected to steadily increase from US $6.6 billion in 2017 to US $7.2 billion in 2020.

In the field of automobile main control chip, GPU will still maintain the mainstream position of general automobile main control chip, FPGA as an effective supplement, ASIC will become the ultimate direction.

At present, artificial intelligence and intelligent driving algorithms have not been finalized. As a general accelerator, GPU is expected to maintain its mainstream position as the main control chip of automobiles for a long time; As a hardware accelerator, FPGA is expected to be an effective supplement to GPU; In the future, if all or part of the intelligent driving algorithms are solidified, ASIC will become the ultimate choice for optimal cost performance.
