• Floating Point<br />
− e300 used a dedicated floating point unit (FPU) for 32-/ 64-bit<br />
floating point registers (Note: e300c2 does not have a FPU)<br />
− e500v2 implements scalar single-precision, vec<strong>to</strong>r singleprecision<br />
and scalar double-precision embedded floating point<br />
categories through the SPE APU<br />
− e500v2 uses general purpose registers, extended <strong>to</strong> 64 bits <strong>to</strong><br />
accommodate vec<strong>to</strong>r and double precision operations<br />
− e300 and e500v2 floating point opcodes are not the same<br />
