Renesas Technology Introduces SuperH(R) Microprocessor That Supports Gigabit Ethernet for Network Devices and Digital Home Appliances.

SAN JOSE, Calif. -- The High-Performance SH7763 Device Has a 2-Channel Gigabit Ethernet Controller and PCI Bus Controller to Enable High-Speed Data Transmissions

Renesas Technology America, Inc. today announced a powerful 32-bit SuperH microprocessor for implementing gigabit connectivity for digital network products. The SH7763 microprocessor suits business products such as IT terminals, VoIP end-points, surveillance cameras, networking infrastructure equipment, and digital home appliances including media receivers, home servers, and PC peripherals.

The new microprocessor incorporates an SH-4A dual-issue superscalar RISC CPU core with a built-in floating point unit (FPU) for higher performance and precise real-time processing capabilities. The SH7763, for example, doubles its performance by achieving 478 million instructions per second (MIPS), and 1.9 giga floating point operations per second (GFLOPS) at the operating frequency of 266MHz. The 7-stage pipeline in the RISC core and the 10-stage pipeline in the FPU enable greater parallelism in instruction execution. The internal SuperHyway bus allows simultaneous transfers of data between memory and peripherals at high speeds. These architectural enhancements in the SH-4A will benefit multimedia and data-intensive applications, such as graphics and video. The instruction set from the new SH-4A core is fully upward compatible with the SH-4 architecture, allowing engineers to utilize existing programs and helps reduce system development time.

The device also provides powerful on-chip functions, including a two-channel Gigabit Ethernet (GbE) controller supporting 10/100/1000 Mbps LANs, and PCI (Peripheral Component Interconnect) bus controller.

The on-chip two-channel GbE controller supports the IEEE802.3 compliant RMII (Reduced Media Independent Interface) interface specification, so it can be used simultaneously with the on-chip 32-bit-wide PCI bus controller that supports the PCI Rev.2.2 standard. The SH7763's PCI bus interface allows seamless communication with IEEE802.11a/g/b compatible wireless LAN chips. When built into digital appliances, the SH7763 has sufficient processing throughput and on-chip hardware functionality to control the operation of that product, while simultaneously handling data traffic from connections to two Ethernet wired 10/100 Mbps LANs and a wireless LAN. By providing both 1000 Mbps (1 Gbps) high-speed LAN support and a high-performance CPU core, the microprocessor enables the fast network transfers essential for high-speed transmission and reception of movies and similar large-volume data.

The security accelerator that the SH7763 provides performs high-speed encryption/decryption processing. It supports Data Encryption Standard (DES), Triple DES (3DES), and Advanced Encryption Standard (AES) as data encryption methods, and Message Digest-5 (MD5) and Secure Hash Algorithm-1 (SHA-1) as authentication data generation methods. The device's two-channel moving-image-stream interface can handle high-speed transfer of the MPEG-2 TS (Transport Stream) transfer format and can connect to an MPEG-2 encoder/decoder chip. Secure transfer of digital content -- such as transmissions from terrestrial digital broadcasting systems -- is made possible by transmitting and receiving the streaming data on a network after performing encryption/decryption processing with the security accelerator on the SH7763.

A double-data-rate (DDR) SDRAM interface integrated in the SH7763 facilitates the high-speed data processing by the SH-4A core and the high-speed data transfers by the GbE, PCI, and security accelerator. The SH7763 makes it possible to implement a highly integrated and high-performance system. Other on-chip SH7763 peripherals include a USB interface, serial communication interface, audio CODEC interface, timers, MultiMediaCard interface, Direct Memory Access Controller (DMAC), color-LCD controller, and more.

Various well-proven development-environment tools are available for the new microprocessor. They include evaluation boards such as Hitachi ULSI Systems' Solution Engine, and the Renesas E10A-USB emulator.
