Table 2

2-D CRA operation based on data flow during one control step.

Data flow step	Boundary node operation	Other node operation
New row from bottom	𝐵(𝑀,𝑗)=InR(𝑗)forall1≤𝑗≤𝑁	𝐵(𝑖,𝑗)=𝐵(𝑖−1,𝑗)forall2≤𝑖≤𝑀;1≤𝑗≤𝑁
New row from top	𝐵(1,𝑗)=InR(𝑗)forall1≤𝑗≤𝑁	𝐵(𝑖,𝑗)=𝐵(𝑖+1,𝑗)forall1≤𝑖≤𝑀−1;1≤𝑗≤𝑁
New column from right	𝐵(𝑖,𝑁)=InR(𝑖)forall1≤𝑖≤𝑀	𝐵(𝑖,𝑗)=𝐵(𝑖,𝑗+1)forall1≤𝑖≤𝑀;1≤𝑗≤𝑁−1
