The SH-Navi3 is a dual-core SoC built around a pair of SH-4A CPUs for superior processing performance of up to 1920MIPS (when operating at 533MHz).
It integrates graphics and image recognition processing functions that have been tweaked for improved performance.
Dual DDR3-SDRAM interfaces, which support simultaneous access, and a PCI Express interface enable ultra-high-speed data transfer. The many on-chip peripheral functions also include a serial ATA interface, allowing increased easy-to-use in car information terminal applications.
