parallel bus

[ssssss]

hi

i want to have 8 powerQUICC || pro processors connected with each other . there will be one master and others are slaves . i wonder if there could be any problem having a parallel bus , with eLBC ?

any body has any idea?

thanks

Have a great day,

The PQ2pro processors do not support master-slave connection/operations like PQ2 on 60x bus. The PQ2pro eLBC bus cannot be shared by several PQ2pro. But you may mean something else. How you are going to connect 8 powerQUICC || pro processors? What powerQUICC || pro interface you want to use to connect?

One can use PQ2pro PCI or PCIe or USB interface and corresponding PCI bridge or PCIe switch or USB hub in order to connect 8 PQ2pro.

my plan is this:

we have one master and others are slaves . so when master wants to speak with a slave it should inform that one ,so i place a decoder for 3 address lines and we will have 8 output signals . each of them would go to a slave's gpio and will be an interrupt. we will use elbc of master and gpio and elbc of slaves (gpio of slaves for having interrupts and elbc for interchanging data)

so what happens briefly is this :

master wants to speak with a a slave. it will have a read instruction , which address is the slaves address . (here i think we have to use relaxed read with some wait time in order to match timings). the slave gets an interrupt and puts data at it's pins,connected to shared bus.and finally master will read data  .

if it is needed i can tell more details.
