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. 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. , GPS Baseband Processor, 2D and 3D Graphics Engines, and over 50 Peripheral Functions; It Enables Simpler Systems That Deliver More and Better Standalone and Networked Applications with Impressive Color Displays Renesas Technology Renesas Technology Corporation (ルネサス テクノロジ| America, Inc. today announced the SH7770 SoC (System-on-Chip) device, an efficient one-chip solution for high-performance car information systems (CISs), especially next-generation car navigation See GPS. and infotainment products that run compelling standalone and networked applications at impressive speeds. It is also an excellent choice for sophisticated digital audio/video products, complex industrial equipment, and other embedded systems Embedded systems Computer systems that cannot be programmed by the user because they are preprogrammed for a specific task and are buried within the equipment they serve. . The powerful processor is based on a newly developed 400MHz SH-4A SuperH(R) Family CPU core that achieves very high performance: 720 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. (million instructions per second Noun 1. million instructions per second - (computer science) a unit for measuring the execution speed of a computer's CPU (but not the whole system); "4 MIPS is 4,000,000 instructions per second" MIPS ), 2.8 GFLOPS See gigaFLOPS. GFLOPS - gigaflops (giga-flops). The generously integrated device provides a new 2D graphics engine for map drawing and a fast, efficient 3D graphics engine for creating impressive color display screens. It also offers a GPS baseband processing function for navigation functions Navigation function usually refers to a function of position, velocity, acceleration and time which is used to plan robot trajectories through the environment. Generally, the goal of a navigation function is to create feasible, safe paths that avoid obstacles while allowing a , plus a comprehensive set of over 50 peripheral modules that engineers can use to simplify and reduce the cost of system designs. By integrating these advanced functions, the SoC device offers a cost effective, single-chip solution that also helps reduce design complexity and saves space. According to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. Anand Ramamoorthy, senior manager, car infotainment and telematics Originally coined to mean the convergence of telecommunications and information processing, the term later evolved to refer to automation in automobiles. GPS navigation, integrated hands-free cellphones, wireless communications and automatic driving assistance systems all come under the group at Renesas Technology America, "The exciting SH7770 is a cost-efficient, single-chip upgrade solution for customers currently using our popular 2-chip solution, the SH-4R processor + HD64404 companion chip, in car navigation systems. Manufactured in 0.13-micron technology, the SH7770 is an industry first: the most-powerful, highest-functionality piece of silicon available today for engineers who need more CPU horsepower horsepower, unit of power in the English system of units. It is equal to 33,000 foot-pounds per minute or 550 foot-pounds per second or approximately 746 watts. and greater module integration. The powerful processor is the key to implementing the increasingly helpful functions that drivers and passengers want in their vehicles." Processing Instructions Quickly, Moving Data Efficiently The 400MHz SH-4A CPU core operates nearly 70 percent faster than the 240MHz SH-4 CPU core used in other SH-4 series devices. The SH7770's cache memory is a four-way design that provides a higher hit rate and helps speed up software processing. Because the instruction set is upward-compatible from the SH-4 CPU core, existing SH-4 application software can be reused, reducing system development times. A 64-bit bus (also usable as a 32-bit bus) allows connections to external DDR-SDRAM DDR-SDRAM - Double Data Rate Random Access Memory (Double Data Rate-SDRAM), while a 32-bit extension bus allows connections to external flash memory or SRAM See static RAM. SRAM - static random-access memory . A unified memory architecture lets specific internal function modules share memory, making it possible to reduce the number of external memory parts. To enable the modules to access external memory efficiently, the SH7770 has a built-in memory controller, a bus bridge and bus arbitration circuitry. Four access-priority levels can be set and modified as needed as needed prn. See prn order. to accommodate changing performance requirements. 2D/3D Graphics Engines Implement Impressive Displays The two graphics engines in the SH7770 improve the quality of system display outputs, while minimizing the processing load on the CPU core so applications can execute faster. In many cases they eliminate external chips that would otherwise be required. The 2D graphics engine can be used to draw high-quality maps quickly for car navigation systems. For example, a special bold-line drawing function makes it easy to create lines of constant width regardless of direction when drawing roads, and makes possible endpoint processing and painting of linked areas. An anti-alias function smoothes drawings of polygons, oblique lines (Geom.) a line that, meeting or tending to meet another, makes oblique angles with it. See also: Oblique , and so forth, for more realistic depictions of geographical features such as parks and schools. This 2D graphics engine is functionally upward-compatible with the Q2SD 2D graphics engine in other Renesas processors, facilitating code reuse Code reuse, also called software reuse, is the use of existing software, or software knowledge, to build new software. Ad hoc reuse has been practiced from the earliest days of programming. Programmers have always reused sections of code, templates, functions, and procedures. . The 3D graphics engine is based on the PowerVR MBX MBX Mail Box (Eudora filename extension) MBX Motherboard Express MBX Management Board Executive MBX Mlada Boleslav MBX Message Bus Exchange 3D graphics IP from Imagination Technologies, Ltd. This engine enables the SH7770 to handle 3D illustrations both for navigation and multimedia applications and is designed to minimize external memory accesses. It produces smooth, high-quality 3D graphic display operations in full color and with anti-alias processing, without requiring a dedicated external graphics memory. Development Tools Accelerate System Design Cycles Renesas Technology and third-party suppliers offer an extensive variety of hardware and software tools that ease and accelerate the development of complex embedded systems based on the SH7770 processor. A key Renesas product is a reference platform that includes CIS-oriented peripheral circuits.
