As does the Analog Devices Blackfin BF535, a 16/32-bit microcontroller/DSP hybrid.

With a flip-flop and a couple gates, you can get the SPORT interface found on ADI DSP's to talk SPI. (Use the frame sync to clock the flip-flop to generate the chip select timing, with a frame sync set to occur before the beginning and end of the transaction, clocking on the trailing edge.)

A TMS320C6711 running at 150MHz should be able to recieve as an SPI slave at up to 9.375MBps ((150MHz/2) / 8), but if you run it as an SPI Master the documentation seems to suggest the divisor of 8 is not necessary so it should be capable of 75MBps.
