Problems 6-42 through 6-47 deal with the same two arrays, a and b, which we will assume

Question:

Problems 6-42 through 6-47 deal with the same two arrays, a and b, which we will assume have been defined in an HDL source file and have the following values: [a] = [10010111], [b] = [00101100]. Output array [z] is also an eight-bit array. Answer Problems 6-42 through 6-47 based on this information. (Assume undefined bits in z are 0.)

What is the value of each of the following:

(a) a[3..0] (b) b[0] (c) a[7] a(3 DOWNTO 0) b(0) a(7)
