Discuss the implementation of floating-point arithmetic operations in the ALU, including considerations for precision and rounding.

2. Determine the representation of the following decimal numbers in the floating point number system of a 32-bit word length microcomputer: (a) (7.90625) 10 and (b) (-12.875)10-

2. Draw the block diagrams and write the truth tables for the following:      a. 3 bit decoder     b. 3 bit encoder

Write an ARM (Keil) assembly program iex.s to assign the hexadecimal equivalent for IEEE 32 bit format of a decimal number in variable ie and extract the sign bit , the exponents and the fraction part in three separate functions (procedures) and shift the bits so that the registers have their actual value and store them in R5Using the extracted bits convert IEEE format to TNS format:In main call functions masking and convert, in masking function, shift the signbit of the varible to left or right according to what shown below. We have these varibles:  R1 shifted to right: 00000000000000000000000000000001 R2 Shift right: 00000000000000000000000010000000 R3 shitft x : 11000000011100000000000000000000 In Convert: conver IEEE format to TNS and store in R5 What I have so far:         Main         LDR R0, =ie        LDR R1,#10000000000000000000000000000000        LDR R2,#01000000000000000000000000000000        LDR R3,#00000000011100000000000000000000         BL masking        BL convert…
