The main reason a single-cycle processor datapath as taught in lectures
must have separate instruction and data memories is because
| the formats of data and instructions are different in RISC-V, and hence different
memories are needed.
O Instruction and Data memory do not have half cycle write back feature
the processor operates in one clock cycle and thus cannot use a (single-ported)
memory for two different memory read accesses (one for instruction fetch and
one for Id instruction) within that same cycle
O having separate memories is less expensive
