The 8088 is architecturally very similar to the 8086. The main difference is that there are only eight data lines instead of the 8086's 16 lines. All of the other pins of the device perform the same function as they do with the 8086 with two exceptions.

The Basic Architecture of the Intel 8088. Below is a block diagram of the organizational layout of the Intel 8088 processor. It includes two main sections: the Execution Unit (EU) and the Bus Interface Unit (BIU). The EU takes care of the processing including arithmetic and logic.

The architecture of 8088 is same as 8086 architecture, but there are two changes. The 8088 has a 4-byte instruction queue in place of 6-byte instruction queue in 8086 and the data bus of 8088 is 8-bit. The other function blocks are the same as the 8086 processor.

Sep 17, 2024 · Though the architecture and instruction set of both 8086 and 8088 processors are same, still there are differences between them. Both The 8088 and 8086 used segmented addressing to allow these chips to address 1 MB of memory …

Feb 2, 2004 · In stark contrast to the 6502 architecture is that of the Intel 8088, released in 1978. The 8088 (and all of its successors, such as the 286, 386, 486, and Pentium series) uses a very different set of registers and a different approach to programming from that of the 6502.

The 8088 was the 8-bit external bus version of the 8086. Each memory word took two accesses. This was to save cost on the memory architecture. The 8088 was chosen by IBM to be the basis of their PC architecture. Embedded control versions of the architecture were introduced as the 80188 and 80186. These included

The 8088 microprocessor can access data in any one out of 4 available segments, which limits the size of accessible memory to 256 KB (if all four segments point to different 64 KB blocks). The 8088 is a version of the 8086 with an 8-bit data bus.

This lecture describes a subset of the 8088 architecture and instruction set. While it’s not possible to cover all the details of the 8088 in one lecture you should learn enough about the 8088 to be able to: write simple program in 8088 assembly language including: (1) transfer of 8 and 16-bitdata between registers

To understand 8088 processor architecture and working principle, we need to understand: what are the CPU registers supported and how they are used (Register Set), what type of memory support is provided (Memory Support)
