SH7774 Soc

Renesas Technology Corp. has added to its SuperH Family the new SH7774 SoC for high-performance in-vehicle information terminals such as next-generation car navigation devices. The new SoC is touted to feature the world's first image recognition processing function, high-speed 600MHz operation, and a varied and comprehensive range of on-chip peripheral modules including a 2D graphics engine for map drawing, an audio encoder, and an Ethernet interface.

The SH7774 is the second-phase product in the company's lineup of car navigation SoCs, following the SH7770 (operating at 400MHz). From August 2006, the company also plans to offer a reference platform that will enable users to carry out efficient system development.

Image recognition processing is essential for driving support systems such as white-line recognition. According to Renesas, the new SoC incorporates the image processing IP introduced by Hitachi Ltd that performs the image processing necessary for recognizing the driving environment based on an in-vehicle camera. It is capable of executing a number of external environment recognition programs simultaneously in real-time. This function makes it possible to implement features for improving driving safety and to create in-vehicle information terminal systems offering higher added value. Renesas plans to release an image recognition library comprising of some 200 functions to simplify the development of image recognition applications.

The new SoC incorporates the SH-4A CPU core and promises a processing performance of over 1GIps at a maximum operating frequency of 600MHz. A floating-point processing unit (FP) operating at the same maximum frequency is also provided. The FPU supports single- and double-precision operations and offers computational performance of up to 4.2Gflops (giga floating-point operations per second) in single-precision mode.

The device has a 2D graphics engine that implements a variety of drawing functions at high speed, the company said, as well as peripheral modules necessary for next-generation car navigation systems such as sound interfaces, an ATAPI interface, an Ethernet interface and a CAN in-vehicle LAN interface. In addition, the use of a Unified Memory Architecture allows memory to be shared by different modules, enabling the number of external memory parts to be reduced.

These varied peripheral functions enable the main functions of a system to be implemented with a single chip, making it possible to cut down on the number of component parts and create a high-performance system at lower cost.

Sample shipments will begin July 31 in Japan. The package used is a 554-pin BGA (29-by-29mm). Sample pricing is $129.14.
