Question

1. Assembly language instruction format is composed of and are statements within the assembly program used only by the assembler 3. The names (symbol and full name) of the two 16-bit registers in 8051 are: 4. IF the addressing space of a memory is from 000 to 7FF then the size of the 5. The term CPU stands for 6. 8051 is and memory is bytes. and is composed of and units anbit microcontroller 7. 8051 has byte RAM Complete the following table by writing the "less", “more" or " same" in each entry: Criteria Area Power Consumption Devices No. of Instructions Microprocessors Microcontrollers

Explanation / Answer

1) Opcode(operation code) and (source/destination address/register)

2) Insruction Set statements

3) Data Pointer(DPTR) and Program Counter (PC)

5) Central Processing Unit, composed of control unit and Arthimetic-Logic Unit

6) 8051 is 8-bit microcontroller

7) 8051 has 128 bytes RAM

Comaprison

1) Microprocessors has less devices, microcontroller has more devices

2) Power Consumption is more in Microprocessors and less in microcontroller

3) More ares in MicroProcessor , less in Microcontroller

4) Microprocessor has more no. of instruction , less in Microcontroller.
