Some of the arrays (especially the mapped pixel type) often return arrays with an unsigned 8-bit value. These arrays will easily overflow if you are not careful. NumPy will use the same coercion that you find in C programs, so mixing an operation with 8-bit numbers and 32-bit numbers will give a result as 32-bit numbers.

Combinatorial Array Multiplier (cont.) • Array multipliers are highly inefficient: – Need n n-bit adders => number of gate counts is proportional to n2 – Impractical for large numbers such as 32-bit or 64-bit numbers typically used in computers – Perform only one function, namely, unsigned integer product similar to the previous design of 4x4 multiplier , we need 4 such 4x4 multipliers to develop 8x8 multipliers. Here we need to first design 8bit and 12 bit adders and by proper instantiating of the module and connections as shown in the figure we have designed a 8x8 bit multiplier.
