Relationship between Load and Store Instructions: When data is loaded from memory to the
destination register and the register is then specified as the source operand for a following store
instruction, the preceding instruction’s load is executed in the WB/DSP stage and the following
instruction’s store is executed in the MA stage. These stages are executed in exactly the same
cycle. Nevertheless, they do not contend. The CPU core and DSP unit use the same data transfer
method. In this case, when the data input to the internal bus is stored to the destination register, the
same data is simultaneously output again to the internal bus.
