Hitachi Introduces New High-End RISC Microprocessor; 360 MIPS Engine Ideal for Personal Access Applications.TARRYTOWN, N.Y.--(BUSINESS WIRE)--Nov. 10, 1997--Hitachi America, Ltd. today announced that its subsidiary Hitachi Semiconductor (America) Inc., introduced the SuperH(TM) SH-4 series of RISC RISCin full Reduced Instruction Set Computing Computer architecture that uses a limited number of instructions. RISC became popular in microprocessors in the 1980s. microprocessors (MPUs), which perform up to 360 MIPS (Million Instructions Per Second) The execution speed of a computer. For example, .5 MIPS is 500,000 instructions per second; 100 MIPS is a hundred million instructions per second. at a cost of about 10 cents/MIPS. The CPU CPU in full central processing unit Principal component of a digital computer, composed of a control unit, an instruction-decoding unit, and an arithmetic-logic unit. in the SH-4 series processes two instructions per cycle In computer architecture, Instructions Per Clock (Instruction Per Cycle or IPC) is a term used to describe one aspect of a processor's performance: the average number of instructions executed for each clock 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 (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. 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 m 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 See EMI. . 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 See microprocessor. 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 “BGA” redirects here. For other uses, see BGA (disambiguation). A ball grid array (BGA) is a type of surface-mount packaging used for integrated circuits. (Hitachi Part No. 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.
