Using the Altera(R) devices enabled the off-loading of several key functions from the CPU, which resulted in improved video display quality as well as reduced operating frequency, for notable power savings. The HardCopy device with the embedded Nios processor performs video processing, encryption, picture insertion and IP communications functions in the NTT product. Encryption is particularly important for securing the bi-directional communication between the set-top box user and service providers.

"We originally planned to use a gate array for this project, but Altera's HardCopy solution enabled us to get a fully compatible low-cost device in a fraction of the time using significantly fewer engineering resources," said Kazufumi Watanabe, Multimedia System Group at NTT Electronics. "The integration benefits provided by the HardCopy device and Nios processor allow us to provide secure communications with minimal latency and to deliver a high-quality user experience."

NTT originally developed their set-top box using Altera's Stratix(R) FPGA and Nios processor. In seeking to cost-reduce their design for volume production, NTT initially investigated converting their FPGA design to a gate array. This path required significant engineering resources and would have demanded time-consuming simulation of the design before committing to hardware. Instead, NTT opted to use HardCopy structured ASICs. Converting their FPGA-based design to a HardCopy design took less than a month and a half, significantly less time than if they had pursued a gate array. The result was a pin- and function-compatible device with shorter turn-around time than a gate array that also required less engineering effort on NTT's part.

"Windows of opportunity for consumer electronics market success are shrinking, forcing developers to seek and apply new, flexible, low-cost and faster development solutions," said Todd Scott, senior director of Altera's broadcast and consumer business group. "Altera's structured ASIC approach makes particular sense in high-volume, consumer electronics applications like NTT's set-top boxes, where rapidly-developed customized hardware can enable developers to quickly deliver innovation."
