Pros and cons of MIPS relative to instruction set choices

[EvLer]

could someone help me with this, my ideas are sort of not precise

give pros and cons of MIPS relative to these instruction set choices:
1. supporting indexed addressing mode
2. supporting only word-sized access to memory

1. --- dunno, sure if it all were immediate, it would be a mess but other than that, not sure
2. well, all instructions and registers are 32-bits but i think it's all interconnected... i.e. the adressibility and register/instruction size...
anyway... neeeeed some insight

Generally, MIPS are not comparable between different architectures.
Both 1 and 2 normally reference physical memory. These types of instruction were avoided because memory performance is a big factor.

Perhaps this will help
