Car navigation system


Denso Corporation, together with Toshiba Corporation, has developed a new LSI for car navigation systems. The new LSI contains a CPU that provides 600 MHz high-speed processing; the highest frequency in the world for automobile use and three times higher than Densos conventional CPU. This plus Denso and Toshibas upgraded CPU architectures, increase the CPUs processing capability to four times higher than that of the conventional CPU. Densos LSI is 30 times more sensitive to GPS signals than the conventional LSI, resulting in a quicker and more precise display of vehicles position. A navigation display electronic control unit (ECU) using this LSI was installed on the Toyota Lexus GS launched last month in Japan, and will be launched in Europe and the United States this fall. The demand for more sophisticated semiconductor devices is rapidly growing with the trend toward the car navigation system as an information terminal, the development of various safety and driving support systems and the integration of ECUs, said Mitsuharu Kato, managing officer of DENSO Corporation responsible for the ITS Product Division. DENSO will continue to develop on-board semiconductor devices that meet the needs of customers and society. Display functions such as three-dimensional (3D) graphic control and navigation functions including signal processing of global positioning system (GPS) and gyro sensor are typically performed by two CPUs. However, the new LSI CPU is so powerful that it can perform those functions alone. The new LSI is produced using the 90-nanometer process, the smallest size for both automobile and consumer semiconductors. This process allows thinner wiring and smaller devices, leading to greater integration of functions.
