San Jose, Calif.Renesas Technology America Inc. has developed a 32-bit SoC that delivers 1-GIPS/4.2-GFLOPS throughput capabilities, a 3D-graphics engine, and GPS baseband module for car navigation systems and other in-vehicle car information system products.
The SuperH single-chip SH7775 32-bit processor runs at speeds up to 600-MHz. The SH7775 is the third-phase product in Renesas Technology's lineup of car navigation SoCs, which began with the SH7770 and was expanded by the SH7774.
The new device is the successor to the SH7770, offering 50% more CPU/FPU (floating point unit) performancea necessity for meeting the rising design requirements of car information systems.

The enhanced graphics engine built into the SH7775 adds specialized 3D drawing functions for map drawing, while retaining the bold-line drawing and other 2D functions offered by the SH7770 and SH7774 devices.
Capabilities such as triangle 3D drawing and texture mapping enable more realistic location and direction displays on navigation screens. A wide variety of 3D objects, such as buildings and landmarks, can be rendered as part of the map imagery, and this single drawing engine can be used to draw icons, and menus, as well as maps.
The drawing processing performance is up to three times that of the SH7770's engine due to its 150MHz operating speed combined with an
improved rendering method. The result is smooth, high-image-quality 2D and 3D graphic displays.
To facilitate system development, Renesas plans to offer the MAPGL graphics software engine, which has an API (Application Programming Interface) and provides a PC simulation environment. It will further improve application development efficiency by cutting development times by up to 66%. At the same time, the software will make it easier to achieve maximum performance from the SH7775's graphics engine.
Pricing: $70 each.
Availability: July 2007.
