Memory map in SOPC builder

Question

Hi there,

If I have two custom components in SOPC builder with memory mapped as the following:

component 1: base=0x00000020; end=0x0000003f.

component 2: base=0x00000040; end=0x0000005f.

In these two components, should I decode all of the 32bit address bus or should I just decode the lower 7 bits? :confused:

Thanks,

Hua

you should only have to give your custom component a 7 bit bus for the address.

take a look at page 4 which shows that SOPC Builder will do a lot of the work for you in the fabric:
