Example text

2 shows the internal block diagram of the PIC18F452 microcontroller. The CPU is at the center of the diagram and consists of an 8-bit ALU, an 8-bit working accumulator register (WREG), and an 8 Â 8 hardware multiplier. The higher byte and the lower byte of a multiplication are stored in two 8-bit registers called PRODH and PRODL respectively. The program counter and program memory are shown in the upper left portion of the diagram. Program memory addresses consist of 21 bits, capable of accessing 2Mbytes of program memory locations.

For example, hexadecimal number 1F can be written as 1F16 or as 1FH. 6 Converting Binary Numbers into Decimal To convert a binary number into decimal, write the number as the sum of the powers of 2. 1 Convert binary number 10112 into decimal. 2 Convert binary number 110011102 into decimal. 1 shows the decimal equivalent of numbers from 0 to 31. 7 Converting Decimal Numbers into Binary To convert a decimal number into binary, divide the number repeatedly by 2 and take the remainders. The first remainder is the least significant digit (LSD), and the last remainder is the most significant digit (MSD).

7510 in floating point and then calculate the sum of these numbers. 7510 = 0 01110110 (1)100 0000 0000 0000 0000 0000 Since the exponents of both numbers are the same, there is no need to shift the smaller number. If we add the mantissa of the numbers without considering the decimal points, we get: (1)000 0000 0000 0000 0000 0000 (1)100 0000 0000 0000 0000 0000 þ (10)100 0000 0000 0000 0000 0000 To normalize the number, shift it right by one digit and then increment its exponent. 75. 23 BCD Numbers BCD (binary coded decimal) numbers are usually used in display systems such as LCDs and 7-segment displays to show numeric values.
