London 28th July 2008 — Renesas Technology Europe today announced the
availability in Europe of the SuperH™*1 Family SH77650, a SoC product providing
image recognition processing functions for vehicle information terminals, such
as next-generation car navigation systems, and peripheral devices to
assist-safe driving.
The SH77650 provides the same image recognition functions as Renesas’
existing SH7774 high-performance SoC product for car navigation systems.
Developed as a dedicated image recognition processing LSI device, the new SoC
product delivers a superior cost-performance through optimized functionality
and performance.
The device features image recognition processing intellectual property (IP)
from Hitachi, Ltd. This IP covers specialized hardware that performs the
processing necessary to recognize road conditions based on image data captured
by a camera or similar device. It enables multiple external environment
recognition programs to run simultaneously and in real time. These programs can
perform tasks such as roadway lane recognition or detection and tracking of
leading vehicles. This capability makes it possible to realize sophisticated
functions to increase safety when driving a vehicle. In addition, an image
recognition library with approximately 200 functions is provided to facilitate
the development of image recognition applications. It is also possible to use
image recognition applications originally developed for the SH7774 with the
SH77650.
The SH77650 incorporates the SH-4A, the top-end CPU core in the SuperH
Family. At its maximum operating frequency of 300 MHz its processing
performance is 540 MIPS (million instructions per second). The on-chip
floating-point processing unit (FPU) also operates at a maximum of 300 MHz. The
FPU supports single- and double-precision calculations, delivering a maximum
operating performance of 2.1 GFLOPS (giga floating-point operations per second)
in single-precision mode.
A variety of modules, suitable for automotive image recognition
applications, are provided. These include, in addition to an image recognition
processing accelerator, video input interface and display functions, a
dedicated DMA controller, timers, a serial communication interface, and a CAN*2
interface for in-vehicle LANs. Screens up to a maximum WVGA size, 850 x 480
pixel) are supported.
In addition, there is an on-chip bus arbitrator circuit that sets the priority
of attempts by the modules to access the bus. This circuit supports three
access priority levels and makes it possible for multiple internal modules to
access external memory efficiently. The user can change the priority levels in
order to meet the requirements of the CPU or image processing performance. In
this way the maximum performance can be achieved to match the system
configuration and functions.
Furthermore, a 32-bit dedicated bus is provided as an external bus allowing
connection to high-speed DDR1-SDRAM (Double Data Rate 1 - Synchronous DRAM),
and a 32-bit expansion bus enables connection to flash memory or SRAM.
The package used is a 376-pin BGA (19 mm × 19 mm).
Available development tools include the E10A-USB emulator, which connects to a
host PC via a USB bus. It also provides on-chip debugging functionality,
allowing real-time debugging at the SH77650’s maximum operating frequency.
