Architecture Of 8088
The register set of 8088 is accurately the same as in to 8086. The architecture of 8088 is also same to 8086 except for 2 changes; a) 8088 has 4-byte instruction queue and b) 8088 has 8-bit data bus. The function of particular block is the similar as in 8086.the 8088 architecture is shown in figure.

The addressing capability of 8088 is 1Mbyte, so, it needs 20 address bits, for example 20 addressing lines. When handling this 20-bit address, the segmented memory scheme is utilized and the total physical address forming procedure is the similar as explained in case of 8086. Memory addressingand organization methods of 8088.Whereas physically interfacing memory to 8088, there is nothing such as an even address bank or odd address bank. The total memory is homogeneously addressed as a bank of 1Mbyte memory locations by using the segmented memory scheme. This change in hardware is totally transparent to software. As a conclusion of the modified data bus, the 8088 may access just a byte at a time. This fact reduces the speed of operation of 8088 as compared to 8086, but the 8088 mayprocess the 16-bit data internally. On account of this change in bus structure, the 8088 has different timing diagrams than 8086.

General Data Registers Given figure indicate the register organization of 8086. The registers DX, CX, BX and AX are the general purpose 16-bit registers. AX is behaved as 16-bi
Pointer and Index Registers The pointers contain offset within the specific segments. The pointers BP, IP and SP generally containoffsets within thedata, code and stack segment
