From tiny ARC cores
Oak makes mighty SoCs
Oak Technology is using ARC's USB 2.0 controller core in its new OTI-4110, a programmable system-on-a-chip solution for personal imaging and printing appliances
Oak Technology's Imaging Group required a flexible, efficient USB 2.0 controller that would accelerate the introduction of the OTI-4110 while preserving the full programmability that distinguishes it in the market. ARC's USB 2.0 controller enables PC connectivity to a whole new breed of PC-independent appliances that allow image-rich content such as digital photos, web pages and scanned documents to be captured, manipulated and printed without ever using a PC.
Oak's market forecast for PC-independent imaging devices (digital cameras and imaging-enabled smart handhelds) is expected to grow to nearly 44 million units by 2004, up from 11 million in 2000.
The forecast for PC-independent printing devices, including popular multifunction peripherals, is expected to grow to over 25 million units by 2004, up from 8 million in 2000.
Roger Pennington, vice president - design engineering of Oak's Imaging Group Said: "After an extensive evaluation of the designs currently available, we concluded that the unique architecture and software-based configurability of ARC's USB 2.0 controller matched Oak's needs perfectly".
Customers have licensed ARC's USB 2.0 core for consumer and networking applications that require high bandwidth at the lowest possible chip cost.
SoC-based embedded systems can get to market faster and avoid costly and time-consuming hardware re-spins because USB parameters are configured in software, allowing the designer to accommodate changing application requirements late in the development cycle or even after the hardware has been built.
Oak used ARC's companion programming interface (API) to simplify the development of application software.
Farsad Sarrinfar, senior vice president of marketing and business development for ARC International, said: "Oak's use of ARC's USB 2.0 controller demonstrates that our system-based approach to connectivity fulfils the industry's needs to accelerate development, reduce product cost and get to volume production quickly.
These are the cornerstones of ARC's strategy for bringing value to developers of monolithic embedded systems".
In contrast to competing products, ARC's USB 2.0 controller stores endpoint data in off-chip system memory to conserve valuable die area; small internal buffers isolate the high speed of USB 2.0 from the latency of the chip's system bus.
Like all ARC peripherals, the 32bit Basic VCI-compliant system bus interface (BVCI) smoothes integration into the SoC design.
With ARC's USB 2.0 controller, product developers can control system cost by placing the high-speed transceiver off-chip while retaining full-speed and low-speed operation on-chip.
