Question
1) The following program is a list of instructions for the Basic Computer in hexadecimal code. The computer executes the instructions starting from address 100.
Show the Symbolic instructions with the AC values in the sequence that they are executed.
Note:
1) The complement of a hexadecimal character is computed such that the hexadecimal character plus its complement = 15; i.e. the complement of 0 is F and of A is 5 .
2) Do not include instructions that are not executed
2) List the locations and hexadecimal code of the Assembly Language program below. The locations should be in hexadecimal starting with 100 and ending with 10B.
3) List and briefly define four different kinds of assembly language statements.

The table filled in the sequence of execution is as follows:
2)
The Hexadecimal instruction of the give assembly is as follows:
3)
a) CLA - this is an assebly instruction to tell the processor to clear the contents of the Accumulator. Hence Accumulator is loaded with 0x0000.
b) INC - This assembly instruction Increments the contents in the accummulator by 1 and loads the carry(if any) to E.
c) BUN m - This instruction tells the processor to branch unconditionally to the location specified by m.
d) HLT - This instruction is for the processor to HALT the excution of all the instructions.
