802.11ac IP

Uurmi offers a licensable and silicon independent 802.11ac MAC and Modem core including the protocol software. Combined with any third party 802.11 ac radio, it allows SOC vendors to quickly integrate 802.11ac into their application specific silicon solutions.


Uurmi offers a 802.11ac MAC and MODEM IP, backward compatible with 802.11abgn, supporting data rates up to more than 1Gbit/s. It also supports the 802.11e standard (QoS) and the 802.11i standard (Security) extensions. Uurmi's profound expertise in wireless communications resulted in the highly optimized MAC core with special focus on low memory and MIPS requirements while maintaining a small gate count. This makes Uurmi's Wi-Fi IP solution ideal for power sensitive product applications such as wireless sensor, portable game console or digital cameras - in fact, any application you can think of!


802.11ac MAC IP

Uurmi's IP is an innovative and flexible 802.11ac MAC Intellectual Property composed of hardware and software for easy integration into ASICs and FPGAs. The hardware MAC is in charge of time critical functions such as packet encoding /decoding. AES and RC4 encryption/decryption are also accelerated in hardware. The software MAC, executed from any kind of CPU such as ARM, is composed of LMAC (lower MAC) and is provided with driver for use with the linux mac80211 UMAC protocol stack.


Several partitioning options are supported:

  • Split partitioning: the LMAC is executed on a dedicated CPU to handle time critical functions while the UMAC is running on an application processor which can also run operating system such as linux.
  • Fully embedded: both LMAC and UMAC are running on the same CPU
The software MAC is provided with reference platform drivers and with a small scheduler (or kernel OS) which is a small and efficient Real Time Operating System (RTOS), offering task management, inter-task communications, message (queues and events) management and timing management.

The MAC IP deliverable includes a hardware simulation test bench with regression test suit, synthesis scripts, and a validation tool running under linux.
