The New SH-4A-Based Processor Provides a 50% Performance
Increase Over Its Predecessor with Architectural
Enhancements and Supports Various Memory Interfaces
Renesas Technology America, Inc., a subsidiary of Renesas
Technology Corp., the world's largest supplier of microcontrollers,
today announced the SH7397 "Euclid(TM)" 32-bit microprocessor, a
highly integrated, low-cost device tailored for enhanced telematics
products and similar types of in-vehicle information systems. The SoC
device incorporates a 300MHz, 32-bit SH-4A SuperH(R) superscalar
architecture that achieves processing performance up to 540 million
instructions per second (MIPS) and 2.1 giga-flops (GFLOPS), 50 percent
higher than the previous Renesas "Camelot(TM)" SH7760 processor. The
Euclid processor is upward code compatible with the predecessor to
maximize engineering investments. Moreover, the complex chip with a
built-in floating point unit (FPU) integrates more and better
peripheral functions and interfaces to simplify and reduce the cost of
automotive products, providing drivers and passengers added
capabilities, convenience, and safety.
The Euclid chip is fully supported by a comprehensive hardware
reference platform, "Sequoia(TM)," which includes all of the basic
components to facilitate the development of next-generation telematics
systems. For example, it provides external memory, debug ports, and
various interfaces. It is also capable of supporting real-time
operating systems (RTOS) and middleware, which is currently under
development.
"Our new Euclid SoC is a technology enabler for compelling system
capabilities that will boost consumer demand for OEM and aftermarket
in-vehicle information, safety and entertainment equipment," said Paul
Sykes, marketing manager, CIS/telematics, automotive business unit,
Renesas Technology America, Inc. "Besides its optimum processing
performance for running sophisticated applications, the SH7397 device
provides key system elements supporting those applications, such as a
dedicated bus for external memory and a color LCD controller. The
microprocessor also has a USB interface with a v1.1 (full speed) Host
and a v2.0 (full speed) function controller that enables connections
to consumer devices such as mobile phones, portable music players and
similar types of portable devices."
SH-4A: Top-end 32-bit CPU core with cache, RAM and FPU
The SH7397's high-performance SH-4A CPU core has two separate
32-Kbyte, 4-way set-associative cache memories -- one for instructions
and the other for data -- to improve the cache hit rate for higher
throughput. A fast-access on-chip 16-Kbyte RAM further accelerates
software processing. To meet the demand for faster external memory
accesses associated with higher CPU speeds, the microprocessor has a
bus dedicated for connecting to high-speed DDR-SDRAM chips.
The instruction set of the SH-4A CPU core is upward compatible
with that of the SH-4 core. Therefore, programs written for the SH7760
and other SH-4 series microprocessors can be used on the SH7397,
allowing shorter product development times and lower development
costs.
Wide variety of peripheral functions enables lower-priced systems
The Euclid SoC device incorporates many versatile on-chip
peripheral functions that can reduce the overall system cost of
telematics products. For instance, it has the previously mentioned USB
v1.1 host and USB v2.0 function controller and an LCD controller that
can produce approximately 64,000 colors on an 800x600-pixel LCD panel.
Other peripheral functions include a 4-channel 10-bit A/D converter,
real-time clock (RTC), 6-channel timer (TMU), interrupt controller,
and 6-channel direct memory access controller (DMAC) that allows
high-speed data transfers to and from memory.
A comprehensive set of interfaces is also provided. A serial sound
interface and audio CODEC interface allow transmission and reception
of the voice and audio data essential for a hands-free function.
Memory card interfaces support popular card types (MultiMediaCard, SD
memory card, PC card, and smart card) so multimedia and other data can
be exchanged and stored using the card best suited to the application.
Network interfaces are a CAN interface (the de facto in-vehicle LAN
standard) and an Ethernet controller that can be used both as a
general-purpose LAN interface and as a link for software debugging.
Additionally, there is a 3-channel serial communication interface with
FIFO (SCIF), a 3-channel serial I/O with FIFO (SIOF), and a 2-channel
I2C bus interface.
Comprehensive, modular reference platform using the Renesas Euclid
SoC
The comprehensive suite of hardware and software development tools
available from Renesas and a large community of third-party vendors
allow automotive system developers to build telematics systems easier
and faster than ever. The Renesas Sequoia platform includes the Euclid
SoC, external memory, debug ports, and several peripheral functions
for audio, display, CAN and interfaces such as USB, PCMCIA, MMC, smart
card, SD memory/IO card and Ethernet. The platform can support major
operating systems such as QNX(R), VxWorks(R), WindowsCE and embedded
Linux. For expansion, optional support such as Bluetooth and GPS
modules is also available. The platform leverages the expert
technology resources of the COMET (Community Enabling Telematics)
consortium to simplify the development of low-cost telematics systems
and accelerate time to market. For more information about the COMET
