UWB MAC has high throughput, less pin count

Faraday Technology Corp. has released the UWB medium access controller (MAC) solution, the latest addition to its ASIC design service and broad IP portfolio. The UWB solution enables higher transfer rate at lower pin count for SoC designs. Faraday will be demonstrating the UWB MAC IP with a video streaming platform at the 7th Embedded Systems Conference-Taiwan (ESC-Taiwan) on Aug. 23-24 at the Taipei International Convention Center.

UWB is a technology for transmitting data over a large bandwidth while sharing spectrum with other wireless applications. Driven by WiMedia Alliance, UWB is a booming technology that aims at high-speed wireless, personal-area network in the multimedia-capable PC, consumer electronics and mobile markets. However, most of current UWB ASSPs can only achieve 100Mbps or less throughput, due to the low bandwidth limitation of USB and SDIO interfaces. Although UWB with PCI interface has better performance, it comes with too many pin counts, and thus undesirable for the pad-limited deep-submicron SoC designs. By integrating UWB MAC into the SoC designs, designers can easily achieve 200Mbps+ throughput and significantly reduce the chip's pin counts.

"While most UWB providers focus heavily on interface chips, Faraday is the first ASIC design service company to provide the SoC integration with UWB," said Charlie Cheng, VP of worldwide marketing at Faraday. "The solution of UWB MAC into SoC makes it perfectly fit the high throughput required applications, such as the consumer electronics and the external storage products."

Faraday's UWB MAC solution uses industrial standard MAC-PHY Interface (MPI) as the interface between the SoC and the external UWB PHY chip.

"The novel FIFO and DMA mechanisms make Faraday's UWB MAC an attractive solution that features high throughput and low cost for applications that require multiple streaming supports," said Thomas Hsieh, associate VP of central R&D at Faraday. "Furthermore, Faraday's UWB MAC supports hardware accelerator-based Prioritized Channel Access (PCA). It will be excellent for products that requires high throughput, such as wireless USB, cable replacement products, and personal-area networking applications."

Faraday's UWB MAC IP core is available now. The video streaming demo platform includes Faraday's UWB MAC IP in an FPGA, Faraday's FIC8120 media platform, WiMedia registered PHY and a real-time IP camera and a non-compressed video data streaming from 720 x 1,080 pixel resolution movie clips.
