If you want real proccessors with this stuff, try Cypress semiconductor.
Their PSoC series of parts has had programable logic on board for years.
And I remember an Atmel part many years ago that had an FPGA on board so there is nothing new about this idea.
Seems like this company is just about selling other actual chip companies their concept/stuff to integrate onto an existing processor.
Where can I buy an actual physical processor with this stuff on it, hopefully from a mainstream company, like TI,Microchip, etc
Guess it doesn't exist yet....
