Clearly the market values the MIPS patents more than the products.
I am guessing on-going patent royalties from Broadcom, Cavium and all other licensees will go to ARM/Bridge group, not Imagination.
I wonder if Imagination will continue its own fledgling CPU architecture and MIPS or kill one of the two.
Clearly the merger gives ARM a little more competition as the game increasingly shifts to supplying a full suite of SoC blocks.
Imagination will gain leverage selling graphics and other cores into set-tops where MIPS is strong and Imagination could help MIPS gain more traction in mobile.
