Specifically, Rambus is acquiring digital core IP compatible with PCI Express, Ethernet, SPI-4, USB and SATA protocols, as well as products that are currently in development and will be made available based on customer demand. Rambus will be extending offers to a number of GDA Technologies employees, both in San Jose, California and Bangalore, India that are affiliated with the design and development of these digital IP cores.
    "By adding these IP cores from GDA to our existing line of high-speed interface technologies, we are very well positioned to provide a broad portfolio of easy to use, customer proven and tightly integrated solutions to our customer base," said Samir Patel, vice president of engineering at Rambus. "In addition, a team of digital IP developers in India and the U.S. will join Rambus. Prakash Bare, vice president of GDA's IP business unit, will also move to Rambus as general manager of the Digital IP business. This enables us to accelerate the expansion of our design center in Bangalore, India and gives us an additional ability to attract top engineering talent in that region."
    As part of this agreement, GDA becomes a reseller of these digital controllers and will offer this IP along with its IP and IP-enabled services. Additionally, GDA may use the controllers in custom designs through a technology licensing agreement. GDA Technologies will continue to provide Electronic Design Services, Semiconductor IP, Verification IP and value-added IP-enabled services.
