(2) (Card Information S Products That Offer 2D and 3D Graphics Displays and Sophisticated Operating Features Renesas Technology Renesas Technology Corporation (ルネサス テクノロジ| America, Inc. today announced the SH7785, a 32-bit microprocessor with a 600MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. maximum operating frequency that sets a new speed record for the popular SuperH(R) family. The device incorporates a top-end SH-4A superscalar A CPU architecture that allows more than one instruction to be executed in one clock cycle. See pipeline processing. (architecture) superscalar - A superscalar architecture is a uniprocessor that can execute two or more scalar operations in parallel.

In 1991, this was used of only a handful of highly parallel machines and one sequential processor built with Josephson devices. (giga instructions per second Instructions per second (IPS) is a measure of a computer's processor speed. Many reported IPS values have represented "peak" execution rates on artificial instruction sequences with few branches, whereas realistic workloads consist of a mix of instructions and even applications, ) performance for fast program execution. It also has a floating-point processing unit (FPU (Floating Point Unit) A computer circuit that handles floating point operations. FPU - floating-point unit ) that achieves 4.2 GFLOPS See gigaFLOPS. GFLOPS - gigaflops (giga floating-point operations per second) performance for speeding up the generation of 3D graphics. Main applications for the SH7785 are car infotainment system (CIS) products and other multimedia systems that (1) process 2D and 3D color graphics The ability to display graphic images in colors. , (2) require powerful processing, and (3) can use the versatile display capability provided at low cost by the multifunction display unit built into the chip. The SH7785 microprocessor offers 50 percent more speed and enhanced functions compared with the SH7780, the 400MHz device used in many CIS products now in production.

For example, a valuable new feature for a car navigation See GPS. system is one that shows an annotated 3D picture of what the driver can see through the windshield, created based on the vehicle's location and speed and direction of motion. Implementing such a feature requires considerable processing power and excellent display control -- both of which the SH7785 provides. Many other intriguing features and exciting new applications can be enabled by the new SuperH microprocessor, which saves development time and resources through upward compatibility that allows the reuse of application code written previously for other SuperH processors. "The new SH7785 processor addresses the growing industry need for increasingly sophisticated and versatile products which can also reduce the number of system components to cut costs," said Paul Sykes

"Besides its powerful processing speed See MHz. and sophisticated multimedia functionality, the device also enables engineers to make use of previously developed software assets, which is becoming an increasingly important consideration for system developers."

It allows up to about 260,000 display colors for highly expressive image and video displays. The display unit also offers other advanced control capabilities, such as transparency processing and overwriting Overwriting An options strategy that involves the sale of call or put options on stocks that are believed to be overpriced or underpriced. The options are not expected to be exercised. Notes: Also referred to as overriding. of text information during streaming video playback. Because multimedia systems with fast, high-quality displays typically use external memory for a display data buffer, the SH7785 has a 300MHz, 32-bit dedicated bus. That bus can connect to high-speed DDR (Double Data Rate) Refers to an SDRAM memory chip that increases performance by doubling the effective data rate of the frontside bus. For more details, see SDRAM. DDR - Double Data Rate Random Access Memory 2-SDRAM (Double Data Rate 2-Synchronous DRAM), providing a maximum data transfer rate of 2.4 Gigabytes/second. Besides the LCD panel controller, a variety of peripheral functions are integrated into the SH7785 to simplify and reduce the cost of embedded multimedia systems. --A hardware data translation accelerator useful for moving-image playback provides high-speed execution of motion compensation, color data format conversion, and more. Used in combination with the display unit, it enables moving-image playback and display to be performed by the SH7785 alone. --A PCI bus controller enables easy, flexible system expansions that use existing inexpensive external PC peripherals. It also enables the implementation of sophisticated display functions via an external connection to a high-performance PCI-complaint device with 3D display functions. Other on-chip peripherals include a direct memory access controller, interrupt controller, watchdog timer, various serial interfaces, and an interface for connection to an audio CODEC IC. The SH7785 includes an on-chip debugging function that lets engineers perform real-time debugging at up to the device's 600MHz maximum operating frequency. An E10A-USB on-chip debugging emulator is available as a development environment and a full suite of software tools is offered. In planning is an E200F full-spec emulator with enhanced debugging functions. It will be compatible with the SSTL SSTL Surrey Satellite Technology Ltd SSTL Stub Series Terminated Logic SSTL Site Specific Target Level SSTL Solid State Track Link 18 trace interface comprising the new AUD AUD In currencies, this is the abbreviation for the Australian Dollar.
