Detroit, MI; Convergence 2000 conference -- (press release excerpt) -- Hitachi Semiconductor announced the SH7760 'Camelot', a low-cost and high-integration system-on-chip processor targeting next generation automotive telematics products. The Camelot is based on 32-bit superscaler SH-4 RISC CPU core and operates at CPU clock rates of up to 200 MHz.

The SH-4 CPU core incorporates an on-chip floating-point unit (FPU), which eliminates the need for a separate DSP device to run echo cancellation and other signal-processing-intensive middleware in many systems. 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.

The Camelot's comprehensive set of built-in peripheral functions include system timers, a watchdog timer, memory management unit, clock pulse generator with phase locked loop (PLL) and power-down modes, interrupt controller, direct memory access controller, and bus-state controller. A built-in color LCD controller supports simple displays for navigation functions. Other input/output interfaces include: a multi functional interface which allows the MPU to connect directly to other processor chips; a 10-bit 4-channel analog-to-digital converter; 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 device also has MultiMediaCard, 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.

Hitachi's modular "Biscayne" SOC development platform for the Camelot SOC is a 2-DIN sized unit that runs from a 12V DC source and uses many automotive-grade components which 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 MB of RAM and up to 32MB of Flash. Currently, the Biscayne platform supports the QNX RTOS; but the future software support plan for the Biscayne platform includes VxWorks, Windows CE for Automotive, and Linux, Java support (IBM, OTI and Sun Java Virtual Machine), and middleware (speech recognition, echo cancellation, etc.).

The Camelot SOC will be available during Q1 2003.
