There is an ever-increasing demand for more functionality and complexity to be added to wireless access points. To address these requirements, systems designers must rely on hardware implemented features like dedicated programmable classification, hardware-based queuing and QoS with inter-layer optimization; these provide superior performance versus software-based implementations and also provide tight latency bounds in serving low power clients. In this … Continued

Policy frameworks usually can vary broadly from one system vendor to the next, from a no-rules approach to performing deep packet inspection-based classification. However, all policies need to be based on Mobility policies per user ID Applications like SIP, H.323, Skype, MSN Messenger AP and station location Port’s subnet SSID of the wireless network It is also essential that the … Continued

The data bandwidth requirements of Wi-Fi devices have been increasing tenfold every five years while the number of Wi-Fi devices inside the home is doubling every year. This means the data processing requirement of wireless access points is growing at a compounded rate. With the advent of devices with 802.11ac connectivity, the trend is expected to continue at a much … Continued

In an article published a few months ago, I gave an overview of the new Ensigma Series5 RPUs and talked about the support we offer for customers targeting various global or regional video broadcast standards. In this blog post, I would like to describe how Ensigma RPUs also support for radio broadcast standards. There are many flavors to audio broadcast … Continued

When we originally introduced the Ensigma Series4 RPU family, we mainly focused on the support for different connectivity standards such as Wi-Fi and Bluetooth. However, there were also several mentions of the Ensigma’s capability to support broadcast TV and radio standards. In this two part article, I would like to reveal some details about a next generation broadcast TV standard … Continued

In a previous post my colleague Kevin McDermott laid out the processing requirements for IoT devices. He also touched upon the data rate requirements for IoT. Today I’d like to talk about our Ensigma Whisper RPU architecture, a hardware connectivity engine optimally designed for IoT applications. The Whisper family offers a unique and comprehensive range of multi-standard solutions for embedding … Continued

Since their release, the Ensigma Series4 family of Radio Processing Units (RPUs) has been the powerhouse for high-performance connectivity standards such as 802.11ac 2×2 and 802.11n 4×4 as well as many TV and radio broadcast standards supported by Imagination. Multiple customers have licensed these RPUs to integrate more (or all) high-performance connectivity on-chip; examples include S2-Tek, Toshiba, Elvees, Rockchip, and … Continued
