Ethernet Controller

Andre was chief Architect of the ThunderLAN integrated PCI 10/100 Ethernet Media Access Controller, and designed the MAC and list management functions. This controller supported both 802.3 (Ethernet) and 802.12 (Demand Priority). This was TI’s first PCI bus master implementation and was designed for maximum PCI throughput.


Cards based on ThunderLAN were sold by Compaq under the “Netflex” brand name for over 5 years.
