Extended array manifolds: functions of array manifoldsThe response of an array processing system has been widely modelled using the concept of the array such as monads and type classes, to provide multiple interpretations of circuit circuits for implementation on Field Programmable Gate Arrays (FPGAs).

The type which we use defines the characteristics of our data. We can use types which interpret data purely as logical values, for example.

You can do assignments and arithmetic operations with arrays. You can also pass multi-dimensional arrays to functions, and use them in instantiations. The array must be fully constrained in all dimensions. The array is declared as an integer-indexed array, but the address port is modelled as a std_logic_vector signal. Type mismatch! To get round this we use the to_integer function from IEEE package numeric_std.
