Load Effective Address
Description
Compute the absolute (effective) address defined by the addressing mode and put the result in address register
A[a].

LEAA[a], A[b], off10 (BO)(Base + Short Offset Addressing Mode)
EA = A[b] + sign_ext(off10);
A[a] = EA[31:0];
LEAA[a], A[b], off16 (BOL)(Base + Long Offset Addressing Mode)
EA = A[b] + sign_ext(off16);
A[a] = EA[31:0];
