Question

A b) COMP is a two dimensional annay with 10 nows and
5 columns. Each elements of the annay is stoned
in a memory location. If COMP [1] [2] begin at Addness
400. find the location COMP [4] [5] the annangement:
6 Column
major .
a) Row major​

Answer 1

Answer:

Address of [I, J]th element in row-major = B + W[C(I – Lr) + (J – Lc)]

Column-major Implementation

In this method, the first column elements are placed first, then the second column elements and so on.

The formula to calculate the address of [I, J]th block is:

Address of [I, J]th element in column-major = B + W[R(J – Lc) + (I – Lr)]

Note that:

B is the base address (address of the first block in the array).

W is the width in bytes (size in bytes for each block in the array).

Lr is the index of the first row.

Lc is the index of the first column.

R is the total number of rows.

C is the total number of columns.
