The 8086 is a 16-bit microprocessor, it can transfer 16-bit data. So in addition to byte, word (16-bit) has to be stored in the memory. This is stored by using two … Read More »
Web17 sep. 2014 · For 8086, when reading from ROM, The least significant address line (A0) is not used, reducing the number of address lines to 19 right then and there. In the case where the CPU needs to read 16 bits from an odd address, say, bytes at 0x3 and 0x4, it will actually do two 16-bit reads: One from 0x2 and one from 0x4, and discard bytes 0x2 and … WebDesign 8086 based system with following specifications.
