The DS-X has a built in processor that was hidden from everyone including the people who bought the cart (might explain the burn on the chip that people found when they opened their DS-X, maybe the team was trying to hide it from the curiuos minds out there), It's a 333Mhz processor that's like 10 times faster than the processors in the Nintendo DS Itself! (same one in the PSP basicly)

To wrap up the FPGA talk, picture this, the FPGA device sitting inside your DS Xtreme has enough “room” to fit a complete ARM9 core and can be clocked at over 300Mhz !
... not exactly. Besides, it'd eat your battery if it was clocked at those speeds.

FPGAs are generally slower than their application-specific integrated circuit (ASIC) counterparts, can't handle as complex a design, and draw more power.

Some engineering applications have used a single FPGA device to replace the function of a simple embedded-microcontroller. More recently, a complete 32-bit CPU (Central Processing Unit) core can be implemented through the programmable logic of a high-capacity FPGA. Such CPU cores are known as "soft CPU cores," examples of which being MicroBlaze™, Nios II™ and LatticeMico32™ by Xilinx, Altera and Lattice respectively.

Beyond this, some FPGA devices contain dedicated hardware CPU core(s). Selected Virtex parts from Xilinx contain 1 or more IBM PowerPC 405 CPU embedded cores, in addition to the FPGA's own programmable logic.
