Answers
Answer:
The arithmetic and logic unit is 8-bit unit. 2) It performs arithmetic, logic and rotate operations. 3) It consists of binary adder to perform addition and subtraction by 2's complement method. ... 5) Accumulator, temporary register and flag register are closely associated with A.L.U.
Explanation:
Answer:
For me MP is bit difficult subject... but ill try my best to answer for this question .
1st we need to know what is MICROPROCESSOR ?
Computer's Central Processing Unit (CPU) built on a single Integrated Circuit (IC) is called a microprocessor.
- A microprocessor consists of an ALU, control unit and register array. Where ALU performs arithmetic and logical operations on the data received from an INPUT DEVICE or MEMORY. Control unit controls the instructions and flow of data within the computer. And, register array consists of registers identified by letters like B, C, D, E, H, L, and ACCUMULATOR.
Explanation:
1. The arithmetic and logic unit of this is 8 bits .
2. It performer's ARITHMETIC,ROTATE and LOGIC operations.
3. The results of this is typically stored in ACCUMULATOR (AC).
4. The Temporary Register is used to HOLD Data during an ARITHMETIC and/or LOGIC operations.
5. ACCUMULATOR, TEMPORARY REGISTER and FLAG REGISTER are closely associated with ALU
6. it performes Addition and subtraction by 2S complement method.
7.All flags are set and reset according to the operations.
i hope it will help you...
