Instruction in 8086
Nettet25. feb. 2024 · It has an instruction queue, which is capable of storing 6 instructions bytes from the memory, resulting in faster processing. 8086 microprocessors can come in many variants, such as 8086-1 and 8086-2. The clock speed of 8086 is 5 MHz, 8086-2 is 8MHz and 8086-1 is 10 MHz. It consists of 29,000 transistors. NettetThe 8086 and 8088 implement AAA differently than later processors. On the 80286 and later processors, the first addition is performed on AX instead of AL, incrementing the AH register if a carry is generated out of AL. If AX contains OOFFh, executing AAA on an 8088 will leave AX=0105h. On an 80386, the same operation will leave AX=0205h.

The XLAT and XLATB instructions get the base address of the table in memory from either the DS:EBX or the DS:BX registers (depending on the address-size attribute of the instruction, 32 or 16, respectively). (The DS segment may be overridden with a segment override prefix.)
