You need to consider some other requirements to make this decision. If the 823 would be enough performance, you can step up to the 860(D/T/P) and get more performance. Depending upon the application, the 860P can be higher performance than the 405 because it will offload the integrated peripherals to the CPM. The highest performance of the bunch is the 82xx, which also includes hardware floating point, if that is important. > ....

I've used them all, and they all have advantages and disadvantages. You didn't list many requirements that would clearly show one is better suited for your application. Based on what you said, and past experience with the 823, I would choose something from the 855/860 family. -- Dan ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
