Function

Where i goes from 0 to (LPM_Width - 1).

Example

Suppose the designers have three 8-bit buses and they want to AND the corresponding bits of the three buses. This is done using an LPM_AND with an LPM_Width = 8 and an LPM_Size = 3. The LPM_Width of eight indicates that there are eight AND gates, and the LPM_Size of three indicates that each AND gate has three inputs.

The function performed by the LPM_AND gate in this case is:

Out[0] = Result₀ = Data_0X0 & Data_1X0 & Data_2X0 = C[0] & B[0] & A[0]

Out[1] = Result₁ = Data_0X1 & Data_1X1 & Data_2X1 = C[1] & B[1] & A[1]

Out[2] = Result₂ = Data_0X2 & Data_1X2 & Data_2X2 = C[2] & B[2] & A[2]

Out[3] = Result₃ = Data_0X3 & Data_1X3 & Data_2X3 = C[3] & B[3] & A[3]

Out[4] = Result₄ = Data_0X4 & Data_1X4 & Data_2X4 = C[4] & B[4] & A[4]

Out[5] = Result₅ = Data_0X5 & Data_1X5 & Data_2X5 = C[5] & B[5] & A[5]

Out[6] = Result₆ = Data_0X6 & Data_1X6 & Data_2X6 = C[6] & B[6] & A[6]

Out[7] = Result₇ = Data_0X7 & Data_1X7 & Data_2X7 = C[7] & B[7] & A[7]
