Hitachi's Low-Cost SuperH System-on-a-Chip Processor is Tailored for Low-End to Mid-Range Telematics Systems
DETROIT--Oct. 21, 2002; At the Convergence 2002 conference today in Detroit, Hitachi Semiconductor (America) Inc. -- a leading supplier of microprocessors (MPUs) and microcontrollers (MCUs) for embedded systems -- announced the economical SH7760 "Camelot(TM)" SuperH(R) RISC system-on-a-chip (SoC) device. Its performance characteristics and many built-in peripherals are tailored specifically to facilitate the design of the next generation of low-/ to mid-range automotive telematics products.The Camelot SoC device is based on a proven 32-bit superscaler SH-4 RISC CPU core that executes two instructions simultaneously. The core runs at up to 200 Megahertz (MHz) and operates with an on-chip cache and RAM to deliver high performance: up to 360 million instructions per second (MIPS) and 1.4 giga-flops (GFLOPS). Telematics system engineers can use this high-speed processing throughput to implement more and better convenience and safety features, such as hands-free calling for cellular communications.
With FPU, separate DSP device isn't needed
The SH-4 CPU core incorporates an on-chip floating-point unit (FPU) -- a fast hardware accelerator for mathematical operations. The FPU eliminates the need for a separate DSP device to run echo cancellation and other signal-processing-intensive middleware in many systems. Thus, it enables simpler, smaller, less-expensive telematics system designs. In addition to the Camelot SoC, Hitachi also offers the recently announced HD64404 companion chip and SH-4 CPUs for high-end multimedia and navigation applications within the car.
"Hands-free calling is beginning to be a 'killer application' in the low-to-medium end of the telematics product spectrum, a compelling reason for consumers to buy a system. The Camelot chip is an excellent fit for that capability and much more," said Tatsuo Yamamoto, vice president of CIS/Telematics business unit at Hitachi semiconductor (America) Inc. "We asked customers what CPU features were needed to produce products that will stimulate consumer interest, acceptance, purchase and use of telematics products. Their responses helped our device engineers design a sophisticated yet low-cost chip that is a true technology enabler. We worked closely with both the telematics service providers (TSP's) and the Tier-1 OEMs in defining the chip specifications."
"Given the rapid evolution of the telematics market," Yamamoto continued, "we are especially pleased about the turnaround time our engineering and production teams achieved for the Camelot SoC device. Hitachi's extensive library of intellectual property (IP) modules helped the teams design, debug and manufacture the chip quite quickly. It took just a little over 14 months to go from device definition to working samples."
Many functions packed into one low-cost IC
The pressure to reduce chip count to decrease manufacturing cost is especially critical in price-sensitive low-end telematics systems. For that reason the Camelot chip, which is built with 0.18-micron process technology (1.5V core and 3.3V I/O), has an exceptionally comprehensive set of built-in peripheral functions. They include system timers, a watchdog timer, memory management unit (MMU), clock pulse generator with phase locked loop (PLL) and power-down modes, interrupt controller (INTC), direct memory access controller (DMAC) and bus-state controller (BSC). A built-in color liquid crystal display (LCD) controller allows simple displays for navigation functions.
There are many input/output (I/O) circuits, too. Key ones include the multi functional interface (MFI), which allows the MPU to connect directly to other processor chips; a 10-bit 4-channel analog-to-digital converter (ADC); 2 channels of Hitachi controller area network 2 (HCAN2) interface for inter-system communication and control; a USB host interface; and two audio CODEC interfaces. The SoC device also has MultiMediaCard(TM), smart card, serial communication, I2C, SSI and HSPI interfaces, as well as a JTAG port for system debugging and 32 general-purpose I/O ports.
Industry analyst: Peripheral functions and capabilities are
exactly right
According to Egil Juliussen, principal technology analyst at Telematics Research Group, "Hitachi's SH-4 microprocessor family is entering the cell-phone integration telematics market, which is the fastest growing telematics segment. TRG is projecting that cell-phone integration telematics systems will grow from less than 100,000 units annually in 2002 to nearly 10 million units annually worldwide in 2010."
"Hands-free, voice activated communications from within the vehicle require a low-cost telematics solution. Hitachi's movement into this segment improves their competitive position," adds Juliussen.
Compatible CPU core can reduce need to write new software
Camelot's SH-4 RISC CPU core is software compatible with the popular SH7750/7750R and SH7751/7751R SH-4 series MPUs now being used for high-end telematics systems. The core is also upward compatible with devices in the SH-2 and SH-3 series, which are well established as popular embedded system solutions. This compatibility helps reduce system engineering time and cost by permitting the use of proven application software developed by customers or purchased from third-party suppliers.
"The Camelot chip is a good fit for our mobile multimedia programs we are currently working on," said Jeff Jones, chief engineer, Delphi Corporation. "It has the required CPU horsepower, feature set and system support to develop timely and cost-effective systems for our customers."
Many system development tools available
Extensive software/hardware development tools for the Camelot SH7760 MPU are available from Hitachi and third-party suppliers. Foremost among the Hitachi products is the modular "Biscayne(TM)" SoC development platform (US7760-HRP13E). It's a 2- DIN* sized unit that runs from a 12V DC source and uses many automotive-grade components. It contains two PCMCIA slots for attaching peripheral devices and allows system engineers to use all on-chip functions, as well as the chip's six power-down modes. The platform has configurable memory and accommodates up to 64 Megabytes (MB) of RAM and up to 32MB of flash.
Currently, the Biscayne platform supports the QNX(R) RTOS (6.2). Future software support plan for the Biscayne platform includes other operating systems (VxWorks(R), Windows(R) CE for Automotive and Linux(R)), Java support (IBM(R), OTI and Sun Java(TM) Virtual Machine), and middleware (speech recognition, echo cancellation etc).
To ease system debugging, Hitachi offers the E10A JTAG connected debugger for real-time emulation and source level debugging. Code development is supported by the Hitachi Embedded Workshop (HEW). The HEW package offers a flexible code development environment with project generation, tools configuration, version control, graphical analysis and debugger control capabilities. It includes a set of fully integrated software tools: editor, C compiler, assembler, linker, librarian, and simulator.
