The SH7776 (SH-Navi3), from Renesas, is a dual-core system-on-chip (SoC) device with enhanced on-chip graphics functions and a high-performance image recognition processing function for the next generation high-performance car information terminals. The device integrates two SH-4A high-performance 32-bit CPU cores on a single chip and achieves a superior processing performance of 1,920 million instructions per second (MIPS), when operating at 533 MHz.
The SH7776′s 3-D graphics engine features PowerVR SGX IP from Imagination Technologies Limited (IMG). It enables polygon performance of approximately twice than PowerVR MBX used in the earlier SH-Navi1 and SH-Navi2 devices. This provides support not only for 3-D rendering in navigation applications, but also for multimedia applications such as Human Machine Interface (HMI) that demand more colorful and realistic 3-D rendering.
Renesas SH7776 Features
- Incorporates a 2-D and 3-D graphics processor for detailed map rendering and more easy-to-use operation screens
- Features a two-channel 16-bit dedicated bus interface operating at 533 MHz for connecting high-speed DDR3-SDRAM, enabling ultra-high-speed data transfer at a maximum of 4.27 gigabytes per second
- Includes a serial ATA interface achieving high-speed connection to hard disks, sound interfaces including an audio encoder, a USB 2.0 Host/Function interface, a TS interface for receiving terrestrial digital TV broadcasts, and a GPS baseband processing module
- The dual-core architecture supports two types of processing: (1) Symmetric multiprocessing (SMP) and (2) Asymmetric multiprocessing (AMP)
