8086 Family Architecture

Write and assemble the following programs and include the start and end addresses for all memory addresses. Show results in following format: 0000h 3Dh mov a,01h 0001h 01h 0002h 3Fh mov [1000h],a 0003h 00h Problem: Clear all memory locations from 2000h to 200Ah. Make every odd bit in memory address C000h and D000h a 0. Do not change any other bit at each address.

Question : Sixteen bytes of data are stored in memory locations YY50h to YY5Fh. Transfer the entire block to the memory locations starting from YY70h.

Develop an assembly language program

I need help with completing the following specification for an assembly language program. This is a practice question. This is part of an overall assignment that I am stuck at. The program needs to check the current disk drive and report: • The drive letter which would normally be assigned by DOS • The amount of used space on the disk • The amount of free space on the disk • An indication that disk reorganisation is advised if the free space falls below 10% of the total available space. Any naming conventions for program labels, sub-programs, variable names etc can be used. Please could each line in the source code be documented with a remark explaining what it does so tha... click for more
