Question: First instruction is load, next is multiply would you have to wait for the first one to finish? Below If there are parallel read instructions - one to global, one to local, will you have to wait for 2 cycles?

Answer: On C4x, you cannot read two words, one from global and one from local external bus, simultaneously. You can fetch an instruction from ext bus while reading data from the other external bus. Parallel write can write two words to two ext buses in the same cycle.
