Can MicroBlaze execute instructions from the OPB (On-chip Peripheral Bus)?
Instruction memory for MicroBlaze is flexible. MicroBlaze can execute instructions that reside in one or more of the following memory locations:
1. From BRAM on the (LMB) Local Memory Bus
2. From BRAM on the OPB bus
3. From external memory on the OPB (This implementations requires a memory controller peripheral.)
