Instrument Cluster
Depending on the display type, a power supply solution for the display
biasing is required on top of the LED or CCVF drivers for backlighting.
The video information is either sent directly or via a LVDS interface
depending on the size of the display.
Micro-controllers aimed at driver information and cluster system
needs to drive multiple stepper motors and displays.
These devices need to integrate:
High performance CPU cores
Multi-channel DMA controllers
TFT controllers
Fast external memory interfaces with adequate system performance to
implement graphic functions such as anti-aliasing, texturing, animation,
chroma-coding, etc.
The MCU also needs to high enough performance speed to service the
stepper motors in real time.
