The Forum asked us why we chose SMP instead of AMP. I don't know how to answer this question. The difference between SMP and AMP is explained in the document, but I don't know why the project chooses SMP instead of AMP. since I entered this project, it seems that the SMP mode has been determined. today, I checked the previous system documentation. The reasons in this document are as follows:
1. Because the core and core of the AMP are completely independent, but the external resource is not very well divided, in this case, you cannot simply change the board, you need to change the hardware architecture.
2. under the Ampersand, each core is an external system. that is to say, each core needs to be loaded, initialized, and configured separately. in this way, the O & M system is greatly affected, so that the Board cannot be simply replaced.
3. the task is fixed in each core by the amp, which is inconvenient for measurement. when the system is updated to a multi-core board, the amp changes are relatively large, but there is almost no need to change it on SMP.
4. SMP is more common and easier to test. In the future, there will also be projects that require SMP, so as to accumulate experience.
