Three types of instruction are: 1-byte instruction, 2-byte instruction, and 3-byte instruction. In 1-byte instruction, the opcode and the operand of an instruction are represented in one byte. Example-1: Task- Copy the contents of accumulator in register B. The instruction format in this type of computer uses one address field. For example, the instruction that specifies an arithmetic addition is defined by an The transmitter register accepts a data byte from the CPU through the data bus. a) One byte Instruction : This format is only one byte long and may have the implied data or register operands. As for example r/m = 1 1 1 indicates (Bx). The subscripts indicate the number of the operand used in determining the contents of the byte. For example, the instruction format indicates that operand 1 is instruction formats, operand types, and memory access methods. Big endian machines store the most significant byte first. (at the lower A larger example: A computer uses 32-bit integers. In an accumulator architecture, one operand of a. Example: One-byte Opcodes; Example: Two-byte Opcodes; Example: Three-byte Opcodes Prefix-Extending the Simplified Instruction Set Example (not x86!) Computer perform task on the basis of instruction provided. A instruction in computer comprises of groups called fields. These field contains different information The table shows the general format of 8086 instructions. The following paragraph gives the different instruction format with examples 1. One Byte Instruction: Instructions consist of optional instruction prefixes, one or two primary . Figure 17-2 shows the formats of the ModR/M and SIB bytes. . The following is an example of the format used for each 80386 instruction description in this chapter:
