Each digit in the number represents a value in power of 2, starting from the RHS (Right hand side). So the value 01010101 0x2 7 1x2 6 0x2 5 1x2 4 0x2 3 1x2 2 0x2 1 1x2 0 641641 85. The first 1 is called the borrow bit In addition 11 10 the first 1 is called the carry bit. If we want to represent a very large number then we need to use many bits and this is not very convenient. Therefore we usually use number systems derived from the binary system and the most commonly used number system are Octal (base 8) and hexademical (base 16) usually we just use the term Hex. A 10, B 11, C 12, D 13, E 14, F 15 To convert, from a binary number to a hex, it can be done very easily, starting from the RHS, every 4-bit from the binary number can be converted directly into a hex digit. For example: 0101 0101 is equal to 55H (H hexadecimal), we have two 4-bit groups 0101 and 0101. Example: 1100 0111 1010 1011 C 7 A B H To convert back ABCDH 1010 1011 1100 1101. There are two types of signed notations, using a sign bit (usually the most LHS bit) and 2s complement. For example using the LHS bit as a sign-bit, (0 is positive; 1 negative ) 10101010 -42 while 00101010 42. To convert a value from X to X using 2s complement, we first do a 1s complement of X and then add 1 to the result. The 1s complement of a binary value is to invert its 0s and 1s. Example: X 00101010 42 first convert X using 1s complement gives 11010101 then add 1 to the result, i.e. In a floating point format, the digits after the decimal point represent value 2 -1, 2 -2, etc. Example, 0. 1010 1x2 -1 0x2 -2 1x2 -3 0x2 -4 0.50.125 0.625 How to represent signed floating point values. A font file must be installed in order to display the corresponding characters. X86 Instruction Set Architecture Tom Shanley Code Is AlwaysThe first byte ranges from 0xA1 to 0xF9, while the second byte ranges from 0x40 to 0x7E, 0xA1 to 0xFE Since the MSB of the two byte code is always set. Thus, in a document that contain Chinese characters and regular ASCII characters, the ASCII characters are still represented with a single byte. So the microprocessor is the most important component in a microcomputer So to study a microcomputer system, we must first understand the microprocessor What is a Microprocessor Processor-on-a-chip can be described as a microprocessor. Pentium series, etc.
