Earlier this year, Marvell announced the industry's first 802.11ac 2x2 combination radio chip, the Avastar 88W8897. That chip pairs near field communications (NFC) and Bluetooth 4.0 with mobile multiple input multiple output (MIMO), beamforming and support for Wi-Fi certified Miracast, a peer-to-peer wireless screencast standard created by the Wi-Fi Alliance.
The 88W8864 is designed to ensure seamless wireless throughput of high-bandwidth data applications and enable reliable, carrier-grade HD multi-stream video distribution over Wi-Fi networks, Marvell said. The chip is said to deliver high-quality, low latency, artifact-free video content across service provider gateways and set-top boxes, the company said.
The 88W8864 will be integrated into a broad range of Marvell’s media platforms, including Marvell’s video and network SoC platforms, Marvell said. The company claims to be a leading provider of the 4x4 architecture since the introduction of the Marvell Avastar 88W8764 802.11n 4x4 SoC in 2010.
"Marvell’s innovation in the wireless space continues to improve the performance and connectivity of both enterprise and consumer applications, such as access points, set-top boxes and carrier-grade high-definition video," said Will Strauss, president and principal analyst at Forward Concepts Inc., in a statement issued by Marvell. "With the release of the Marvell 802.11ac 4x4 chip, the company is bringing to market a low-power solution that offers a significant increase in Wi-Fi bandwidth capacity. As the first wireless provider to introduce a 4x4 802.11ac chip, Marvell is building on its tradition of delivering solutions that alleviate design challenges and enhance the end-user experience."
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
