Since Tensilica is still a private company they don't announce their financials, but they did also announce that their product license revenue is bigger than any other DSP licensing company by about 25% (presumably CEVA is #2) and that they are number 2 in product license revenue for all CPU IP licensing companies, behind ARM at #1 of course.
The accelerating growth in the number of cores is driven by designs ramping to volume in smarphones, digital TV, tablets, personal and notebook computers and storage and networking applications. But the real driver is power: dataplane processor units (DPUs) provide better performance/power/area than classic DSPs and scale from function-specific micro-cores up to large general purpose DSPs.

New design wins are important for future revenue when royalties start to be paid too. Typically a core will be licensed at the start of a project, and it can be a couple of years before the design is complete and the systems start to ship in high volume.
And for anyone visiting Tensilica's offices, they will move buildings the weekend of 20th October (ten days time). They are only moving to the two-storey building across the road so if you go to the old offices you are almost in the right place!
