Design and testing of multiprocessor communication module for automotive applications

U projektu je specificirana i dizajnirana tiskana pločica za komunikacijski modul sastavljen od SPC58 Chorus 10M mikrokontrolera i TI DRA712 aplikacijskog procesora. Fokus dizajna je bila visoka brzina komunikacije putem 1Gb/s Ethernet sabirnice, kontrolirana od strane Broadcom Ethernet prekidača. Mikroprocesoru je dodatno priključena DDR3, Flash i DDRAM memorija. Za vanjsku komunikaciju je na pločici zaduženo CAN-FD, LIN, MIPI i USB sučelje. Dizajn i shema PCB-a su napravljeni u programskom paketu Altium. Za testiranje su napisane jednostavne programske rutine kako bi se ispitala ispravnost i funkcionalnost komunikacijske periferije. Za testiranje su korištene standardne MCAL biblioteke i Autosar OS struktura. Cijeli dizajn je slijedio pravila standardna za automobilsku industriju. Svi rezultati su dokumentirani. Predložena su moguća poboljšanja sustava.The project included specification and design of a communication domain computer module consisting of one SPC58 Chorus 10M microcontroller and one TI DRA712 application processor. The design focus was on high-speed 1Gb/s Ethernet bus communication, controlled by a Broadcom Ethernet switch. Additional DDR3, Flash and DDRAM memory has been added to the system. For external communication, CAN-FD, LIN, MIPI and USB capability has been added. The layout and design of the PCB was done in Altium Designer software package. For testing, simple software checking routines were written to check the correct functionality of the communication peripherals. External memory checks have also been done. The testing was done by using standard MCAL libraries and the Autosar OS structure. The whole design was done by following rules common in automotive industry. All the results were documented and possible improvements of the system have been suggested
