The accelerometer demo shows the performance gains of the 32-bit ColdFire
V1 CPU over the 8-bit S08 CPU. In the data averaging and data filtering
modes, a considerable amount of 16-bit and 32-bit math is required. The S08
CPU is capable of performing these tasks, but it requires a substantial portion
of its bandwidth. In contrast, the ColdFire V1 CPU performs the same tasks
with only a very small portion of its bandwidth. With Flexis QE128
microcontrollers, you can pick and choose the CPU that best matches your
performance needs.
