Renesas Technology Releases High-Performance SuperHTM Family SH7764 for High-End Digital Audio Applications such as HDD Audio and Network Audio SH-4A CPU core, 324 MHz (583 MIPS) operation, and comprehensive on-chip peripheral functions including 2D graphics and ATAPI, enabling implementation of high-performance systems at low cost Tokyo, February 19, 2007 Renesas Technology Corp. today announced the SH7764 microprocessor with a maximum operating frequency up to 324 MHz, incorporating the SuperHTM* 1 Family's top-end SH-4A CPU core and comprehensive peripheral functions, for use in HDD audio, network audio, and similar high-end digital audio devices, and multimedia devices such as car navigation models. Sample shipments will begin in Japan in April 2007. The SH7764 offers the following features. (1) 324 MHz SH-4A CPU core enabling implementation of high-performance multimedia systems The SH7764 incorporates an SH-4A CPU core with a maximum operating frequency of 324 MHz, enabling high-speed audio codec and image data processing. Large-capacity cache memory comprising 32 Kbytes each for instructions and data, as well as 16-Kbyte RAM, helps to speed up software processing. An on-chip floating-point processing unit (FPU) operating at a maximum speed of 324 MHz supports single- and double-precision operations, and achieves maximum computational performance of 2.3 GFLOPS (giga floating-point operations per second) at single precision. The FPU also provides hardware support of sine/cosine operations and vector arithmetic operations, helping to speed up 3D graphics drawing processing. This CPU core enables a high-performance multimedia system to be implemented. For example, using the FPU for MP3 or similar encoding (compression) of CD or suchlike music data by audio codec software reduces the CPU load, and enables multiple applications to be run simultaneously. (2) On-chip peripheral functions necessary for digital audio applications and the like, enabling system cost to be reduced High-end digital audio devices require the following functions. * A storage function for music data and image data * A communication function used for music distribution, interfacing to a CD-DB* 2 , PC, etc. * A display function that implements a GUI* 3 The SH7764 on-chip peripheral functions supporting large-capacity storage include an ATAPI controller allowing connection to an HDD/CD drive, a NAND flash interface, and a memory card controller. A variety of interfaces, including an Ethernet controller and a USB interface are also incorporated, supporting various communication functions, while on-chip display functions include a 2D graphics engine and an LCD controller and digital RGB output function for display purposes. This comprehensive set of on-chip peripheral functions enables the main features of a system to be implemented with a single chip, helping to reduce overall system cost. - more - (3) On-chip memory bus allowing SDRAM connection, enabling construction of a high-speed, highquality display system The SH7764 includes a 108 MHz 32/64-bit bus connectable to high-speed SDRAM. This allows program execution, high-speed image drawing using 2D graphics, and display functions employing the LCD controller and digital RGB output function to be used effectively. < Development Background > The digital audio field that includes HDD audio and network audio systems, and the multimedia field covering such applications as car navigation systems, are witnessing a rapid increase in the popularity of devices handling MP3, AAC* 4 , and suchlike compressed audio data. At the same time, broadband networks, of which ADSL and FTTH (Fiber To The Home) are typical examples, are becoming increasingly widespread, and music and image distribution services are now readily available in the home. With continued growth expected in the field of such devices that connect to networks and handle compressed audio data, there is a demand for higher system performance together with smaller size and lower cost. Renesas Technology has previously released products incorporating an SH-4 or SH-4A CPU core for use in high-performance multimedia devices, and holds a major market share in such fields as car navigation. Now, taking account of the prospects for continued growth in the network connection field, Renesas Technology has developed the high-performance SH7764 microprocessor incorporating a powerful SH-4A CPU core and a range of peripheral functions including a 2D graphics engine, Ethernet controller, USB, and ATAPI controller, to enable systems incorporating network connection and data compression functions to be implemented at low cost. < Product Details > The SH7764 incorporates a high-performance SH-4A CPU core operating at a maximum frequency of 324 MHz, together with a comprehensive set of peripheral functions that provide large-capacity storage and various kinds of communication and display capability, making it possible to greatly reduce system costs in the rapidly growing fields of HDD audio and network audio devices, and in-vehicle information terminals such as car navigation systems. On-chip cache memory comprising 32-kbyte 4-way set associative instruction cache and 32-kbyte 4way set associative data cache helps to speed up software processing. In addition, the SH7764 includes 16 kbytes of RAM allowing high-speed access during instruction data accesses. System performance can be improved by storing exception handling programs, and audio and image processing programs requiring real-time capability, in this RAM. On-chip peripherals for implementing storage functions include an ATAPI controller, NAND flash controller, and memory card controller, while support for communication functions is provided by an Ethernet controller, USB interface, and so forth. On-chip display functions comprise a 2D graphics engine for screen drawing and an LCD controller and digital RGB output function for display purposes. The provision of such peripheral functions enables the principal functions of a system to be implemented with a single chip, greatly helping to reduce system cost. The comprehensive set of onchip peripheral functions also includes an SSI (serial sound interface) for digital audio playback, a serial communication interface with a FIFO (First In First Out) facility (SCIF), an I2 C bus interface allowing interfacing to E2 PROM and the like, a 32-bit timer, a watchdog timer, and a DMA controller, facilitating interfacing to peripheral devices. The package used is a 404-pin BGA (19 mm x 19 mm) with a 0.8 mm ball pitch, allowing low-cost mounting. This is an environment-friendly lead-free package. - more - The SH7764 incorporates on-chip debugging functions that allow real-time debugging at the maximum operating frequency. The E10A-USB on-chip debugging emulator is available as a development environment, and SH7764 system development can be carried out efficiently using the HUDI and AUD functions. With future plans for increased CPU speed, dual-core implementation, and enhanced peripheral function integration including high-speed memory interface support, Renesas Technology will continue to release products tailored to market needs in a timely fashion. < Notes > Notes: 1. * SuperH is a trademark of Renesas Technology Corp. 2.
