Answer:------------
Given,
Expression, X = (A - B * C) + ( D + E) * F
Postfix Notation of given Expression,
==> ( A - B C* ) + ( D E + ) * F
==> (A B C * - ) + ( D E + F * )
==> A B C * - D E + F * +
Here, TOS = Top of Stack
0 Address | 3 Address |
PUSH A (TOS <- A ) | MUL R1, B,C ( R1 <- B * C ) |
PUSH B (TOS <- B ) | SUB R2, A, R1 (R2 <- A - R1) |
PUSH C (TOS <- C ) | ADD R3 ,D ,E (R3 <- D + E ) |
MUL (TOS <- B * C ) | MUL R3,R3,F (R3 <- R3 * F ) |
SUB (TOS <- A - B * C ) | ADD X, R2, R3 ( X <- R2 + R3 ) |
PUSH B (TOS <- D ) | |
PUSH B (TOS <- E ) | |
ADD (TOS <- D + E ) | |
PUSH F (TOS <- F ) | |
MUL (TOS <- (D + E ) * F ) | |
ADD (TOS <- ( A - B * C ) + (D + E ) * F ) ) | |
POP X ( X <- TOS ) |

Group Project 1 The Micro-1 Processor Simulation <Micro-1 Computer> Here's the organization of a computer equipped with a Micro-1 processor Memory contains an array of integer cells: int cell[] = new int[CAP]; where CAP is the capacity of memory. Initially this is set to 256. Internally, the Micro-1 processor is equipped with eight 32-bit data/address registers and two 32 bit control registers: PC, the program counter, contains the address of the next instruction to execute. IR, the instruction register, contains...
