Long description

There are eight CPUs and Memory blocks aligned vertically at the left and right. The blocks from top to bottom are given as follows. 000, 001, 010, 011, 100, 101, 110 and 111. All the CPU blocks are connected to the memory block by passing through three stages, each stage has four blocks. The blocks in stage 1 are 1 A, 1 B, 1 C, 1 D. The blocks in stage 2 are 2 A, 2 B, 2 C, 2 D. The blocks in stage 3 are 3 A, 3 B, 3 C, 3 D. Block 1: CPU block 1 is passing through 1 A, 2 A and 3 A block and connected to Memory block 1. Block 2: CPU block 2 is passing through 1 B, 2 C, and 3 A blocks and connected to Memory block 2. The passing line is denoted by b between these two blocks. Block 3: CPU block 3 is passing through 1 C, 2 A, and 3 B blocks and connected to Memory block 3. Block 4: CPU block 4 is passing through 1 D, 2 C, and 3 B blocks and connected to Memory block 4. The passing line through the block to 1 D is denoted by a Block 5: CPU block 5 is passing through 1 A, 2 B, and 3 D block and connected to Memory block 5. Block 6: CPU block 6 is passing through 1 B, 2 D, and 3 C blocks and connected to Memory block 6. Block 7: CPU block 1 is passing through 1 C, 2 B, and 3 D blocks and connected to Memory block 7. Block 8: CPU block 8 is passing through 1 D, 2 D, and 3 D blocks and is connected to Memory block 8. The passing line between 1 D to 3 D is denoted by a.
