Yes, implementing CPUs an FPGA is not efficient, Xilinx and Altera provide
CHIPS with processor cores, ARM or PPC, and the programable logic, the
problem, this FPGAs are very expensive (hundreds of dolars). The idea with
SAKC is provide logic resources for make peripherals like PWM controllers,
image sensor driver, step motor controller, etc.
