Write the following programs in Intel assembler. Use .cpp source code

4. Write a program that calculates the integer log2 of a number. There is an instruction in Intel assembler, Bit Scan Reverse (BSR), which makes this easy to do. If you execute BSR reg, memory it will scan the word at the specified memory location and put the position of the first (or left most) 1 bit in the register. Bits are numbered sequentially left to right starting at zero. This will be the log base 2 of the number. This method rounds down when the number is not an even power of 2. The log2 of 6 will be 2. int number, result; cout "; cin >> number; _asm { // Use BSR to calculate the log base 2 of number cout "; cin >> number; _asm { // Use BSR to calculate the log base 2 of number cout
