PIPELINE1 - THE DEFAULT CONTENT OF THE INSTRUCTION AND DATA MEMORY UNIT

This page gives an example for the memory contents of the "pipeline1" component. The first table below specifies the default content of the instruction memory unit. It shows the MIPS instructions, which will be executed during the visualization in two different formats, as bitstring and as assembler instructions. These instructions will be loaded from the file "imem.bin" at the beginning of the visualisation. The second table specifies the default content of the data memory unit. It gives the data values in two different formats, as bitstring and as integer values. These data values will be loaded from the file "dmem.bin".
