Hitachi Introduces New High-End Risc Microprocessor

360 MIPS Engine Ideal for Personal Access Applications

Hitachi America, Ltd. today announced that its subsidiary Hitachi Semiconductor (America) Inc., introduced the SuperH SH-4 series of RISC microprocessors (MPUs), which perform up to 360 MIPS at a cost of about 10"/MIPS. The CPU in the SH-4 series processes two instructions per cycle to far outperform other embedded processors at similar operating speeds.

The SH-4 MPU's are ideal for personal access products such as consumer multimedia, appliances and devices that employ sophisticated onscreen displays.

"The SH-4 series extends the long string of SuperH processor price/performance breakthroughs that have helped redefine the embedded processor market," said Kosei Nomiya, president and CEO of Hitachi Semiconductor (America) Inc. "To date, SuperH processors have attained more than 2,000 design wins, and lead in cumulative RISC shipments worldwide. The SuperH family is the ideal microprocessor line for many of today’s and tomorrow's personal access products that make people efficient, mobile and motivated."

The SH-4, the first model of the series, uses a 0.25 5m process and operates at 1.8 volts internally from an external supply that can range up to 3.3 volts. The SH7750 achieves high data transfer speeds (800 MBytes/second, peak) at relatively low clock and bus speeds; this helps minimize radio frequency and electromagnetic interference. The MPU's combination of performance, cache size, and high data transfer rate allows more functions to be executed in software, such as soft modems and MPEG decoders, for enhanced system design flexibility and software upgrades.

The 360-MIPS CPU performance, 1.4-Gflops graphics performance, and 800-MByte/second peak bus bandwidth of the SH7750 is enough processing capability to allow the MPU to be used in virtual reality applications. The chip is a perfect front-end for various 3D graphics architectures. It can assist in the seamless decompression of 2D and 3D media content, thus effectively increasing network bandwidth.

The 200-MHz, 360 MIPS SH7750 2-issue superscalar, SH-4 series RISC microprocessor with a 64-bit external data bus in a 256-pin ball grid array (Hitachi Part #HD6417750BP200) is priced at $40 in quantities of 10,000. Samples and documentation for the SH7750 will be available in the first quarter of 1998 with production quantities available in the third quarter.
