Floating point DSPs from the TI TMS320C3x family are more attractive for a motion control system because their computational power and accuracy is higher than the fixed point TMS320C1x,
TMS320C2x, or TMS320C5x.
Although the achievable number of instructions per second is only slightly higher than that of the fixed point DSP in TMS320C5x family (30 vs 28 MIPS), their speed in floating point operation is impressive: 60 MFLOPS.5, 6, 7, 8, 9 The computation accuracy is also much higher because the
TMS320C3x has a 32 bit data bus.
