LUP Decomposition

LU decomposition stands for Lower-Upper decomposition. LU decomposition is the factorization of the lower triangular matrix and an upper triangular matrix. It is very useful in linear algebra and numerical analysis. A permutation matrix is usually included in the product. Gaussian elimination in a matrix form is known as LU decomposition, When inverting a matrix or evaluating its determinant, this is a crucial step. Tadeusz Banachiewicz, a Polish mathematician, first proposed the LU decomposition in 1938.

Consider the following two operations: (a) PC = PC + 4; (b) PC = PC + offset (offset is a positive or negative multiple of 4).Which of the following statements is true? a In the MIPS architecture, operation (b) is done by performing operation (a) as many times as required. b Operation (a) requires about 1/2 as much hardware to implement as does operation (b) c Operation (a) is simply done by replacing the right-most two bits of PC with 00. d Since (a) is a special case of (b), these two operations require the same hardware to implement.
