|Hitachi Releases HD64404 SuperHTM Companion Chip|
|Ideal for Next-Generation Car Information Systems such as Car Navigation Systems|
- Enables implementation of high-performance, high-functionality car
information systems at low cost -
Tokyo, December 10, 2001 Hitachi, Ltd. (TSE: 6501) today announced the HD64404 integrating functions necessary for Car Information Systems (CISs), for use in next-generation CISs such as car navigation systems. Sample shipments will begin in February 2002 in Japan.
The HD64404 is a companion chip for the SuperHTM*1 family SH-4 high-performance CPU core. Combining the HD64404 with an SH-4 makes it possible to create sophisticated, high-performance Car Information Systems, while the integration of various kind of interfaces, such as in-vehicle LAN or audio etc, and functions necessary for next-generation Car Information Systems makes it possible to reduce the number of system component parts and reduce system costs. In addition, a development platform is available for user system development, enabling users to achieve efficient system development in a short timeframe.
Car navigation systems are becoming increasingly sophisticated in order to handle not only display of road map information, but also real-time road traffic information and new traffic information services provided via the Internet. And next-generation CISs will incorporate various kinds of car navigation system based service information through connection to the Internet or a Traffic Information Center, as well as drive system information covering the engine and transmission and various kinds of sensor data through connection to a CAN*2 or similar in-vehicle network, to provide centralized display and control functions. Thus, CIS equipment will be able to offer centralized control of previously isolated equipment such as air conditioning and audio units, safety checks through the display of vehicle status while running, as well as automotive multimedia functions such as movie distribution via rear-seat displays. The CIS market is expected to show rapid growth as future CISs provide an integrated system combining various kinds of information from entertainment to control and communications, and a car navigation system will be the central item of equipment in a future CIS.
However, incorporating various kinds of information requires a variety of interfaces and peripheral circuits. Previously, a system has been configured from individual devices, but this presents a problem as regards achieving lower costs in the higher-performance, higher-functionality systems of the future. There is thus a strong demand for CIS component devices to incorporate a variety of interfaces and peripheral circuits to enable fewer parts to be used and system costs to be reduced, as well as offering the high processing capability necessary for handling large volumes of information.
Hitachi has previously released the SuperH Family and the Q Series of graphics processing LSIs, which have established a good reputation in the field of car navigation systems. Now, in response to the market needs described above, Hitachi has developed the HD64404 enhanced graphics processing chip for next-generation CIS applications as a SuperH companion chip. Major features of the HD64404 are summarized below.
As described above, the HD64404 incorporates functions suited to next-generation CISs, and use of the HD64404 with an SH-4 makes it possible to implement a high-performance, high-functionality system while reducing the number of parts, thus enabling lower system costs to be achieved.
The package used is a small 352-pin TBGA that allows system size to be minimized.
A development platform is also planned for systems using the HD64404. The platform includes an SH7751R SH-4 CPU core and an HD64404, and is provided with a variety of interfaces including USB and ATAPI as well as an SH extension bus connector and PCI bus connector, simplifying the addition of extended functions by the user. OSs (operating systems) for which support is planned include Windows® CE*5, VxWorks®*6, and QNX® RTOS v6 *7. Use of this development platform will enable fast and efficient development of systems using the HD64404.
Along with the incorporation of the HD64404 as a standard device in CISs, Hitachi will also proceed with the development of products incorporating even higher performance and new peripheral functions to support increasingly sophisticated CISs.
