Lexra

• https://www.linux-mips.org/wiki/Lexra • Jonah Probell has written a history of Lexra.

Lexra did implement a 32-bit variant of the MIPS architecture. Noteworthy architectural feature was the lack

of the MIPS I instructions lwl, lwr, swl and swr that optimize the handling of unaligned loads.

Later the LX4580 core added hardware multithreading. Products implementing Lexra's architecture include

the LX4080, LX4080P, LX4180, LX4280, LX5280 and LX8000. Today Lexra is a defunct company.

Several key employees of Lexra founded the digital video core company Ultra Data Corporation,

the intellectual property assets of which have since been acquired.

Many other key Lexra employees, including co-founder and CEO, Charlie Cheng, now work for ASIC vendor

Faraday Technology in Taiwan, Sunnyvale, CA, and Framingham, MA.

Lexra co-founder and CTO Pat Hays is now vice president of engineering for MIPS Technologies, Inc. in Mountain View.

Realtek RTL8181

• The Realtek RTL8181 is a highly integrated SoC (System-on-a-Chip) with a high-performance 32-bit RISC microcontroller,

two Ethernet MACs and a WLAN controller embedded onto a single chip. PCI Bridge supports one external PCI/MiniPCI device.

The embedded Lexra LX5280 32-bit RISC CPU runs at up to 200MHz and features separate 8KB instruction and data caches.
