hi
Each processing node has its local memory and global memory to share. Each processor and its local memory are connected with local bus. There are also 'routing' issue and 'arbitration' issue.
then
'Is it possible to make MESH-interconnected on-chip 4 processors using BUS ? '
It implicitly mean the interconnection between switches can be a 'bus'.....Maybe my knowledge is short to answer the following question
Thankyou for your remark for beginner
