Core trio boosts SoC platform
Oki Electric has enhanced its uPLAT series of integrated platforms, which lower development times of SoC LSIs, with the introduction of three core products.
More power from laser modules for WDM systems
Oki Electric has developed a trio of high-power 1480nm pump laser diode modules for WDM (wavelength division multiplexing) optical transmission.
Both products are based on an ARM946E general-purpose 32bit microcontroller core developed using mPLAT946E88, Oki's integrated platform solution for system LSI development.
Conventionally the USB 2.0 High Speed interface, the ATA/ATAPI interface, and the SmartMedia standard 2000 compliant NAND Flash interface have used three different chips.
However, Oki has integrated these interfaces onto a single chip, which enables mobile equipment for storage applications to be smaller, lighter and lower in power consumption.
"Oki is the world's first company to integrate necessary interfaces onto an ARM9 based general purpose microcontroller", said Akira Kamo, President of Silicon Solutions Company at Oki Electric.
"As ARM CPU is known for its high performance, low power consumption and high code density, the new microcontrollers will help develop intelligent storage equipment that need security functions and high speed data processing, such as HDD with fingerprint authentication, Flash memory and digital photos".
This ARM946E core microcontroller is also equipped with a multiply-accumulate function that can execute multiply-accumulate operations in a single cycle.
It can be done in such high speed because of the use of separate 8Kbyte cache memories for instructions and data, and also it can encrypt, decode, compress and expand the data.
Oki aims to sell 400,000 units of this series monthly by the fiscal year ending March 2006, targeting the digital home appliances, handheld disk storage products, and PDA equipment market.
Sample shipments start from November 2004, and volume shipments will begin in January 2005.
