SOPC technology applied on automatic mechanical transmission control unit design

A transmission control unit (TCU) based on the SOPC technology was designed, using a large-scale FLASH-based FPGA with analog channels. The functions of TCU are reasonable distributed between hardware and software for both of them being programmable. IP modules including the open-source cores and custom modules are integrated into FPGA in hardware design as well as the modular idea is applied to software design. By co-design, TCU can fulfil the requirements of control functions of automated mechanical transmission (AMT) with lower power, better flexibility and higher speed.
