All in one package ? No.

Triscend do a 80C51 + FPGA -> needs external loader, no ADC
SoftCores + Std FPGA -> needs external loader, No ADC
ActelProASIC -> Is FLASH, but needs Core + ADC
STm uPSD family -> Has CPLD to 32 MCells Q42003
Cygnal -> FLASH.ADC, needs external FPGA
Generic DSP devices -> needs external FPGA

You need to nail down just how much DSP or control maths you
need, and then find out how much of the small FPGA cannot be
done in SW, or in the case of uPSD, in the Timer/Counter
Peripherals assisted by the CPLD.
