Wayne_h, thanks for the history! I had no idea of the origin of the memory designs. I am wondering if the lawsuit involves the general use of POE or some specific technical implementation or features for the particular devices targeted in the lawsuit? Anyone know the particulars?
Ride To Work needs to learn some history of the Semiconductor industry.
Mosaid pioneered the analysis and forensic reverse-engineering of memories (initially) and later processors, assisting and providing data to semiconductor companies in patent infringement lawsuits (for example, when a competitor comes out with a strikingly similar product 9 months after some key personnel leave for the competitor).
Eventually Mosaid developed their own memory designs which they licenced to numerous semiconductor companies. Today ALL of the Korean and Japanese DRAM makers (plus a few others) manufacture Mosaid designs, not their own designs.
The analysis and reverse-engineering part of the business was spun off into a separate company, Semiconductor Insights which was later purchased by the UBM Techinsights conglomerate.
Blog Doing Math in FPGAs Tom Burke 13 comments For a recent project, I explored doing "real" (that is, non-integer) math on a Spartan 3 FPGA. FPGAs, by their nature, do integer math. That is, there's no floating-point ...
