8051 Assembly Language Coding

I'm looking for assistance with 8051 assembly language codes for several tasks. The tasks include:

1. 8-bit Arithmetic Operations:
- Addition
- Subtraction
- Multiplication (MUL)
- Division (DIV)

2. Data Block Transfer:
- Transfer a block of 10 bytes from RAM locations 45H-49H to RAM locations 79H-70H after adding 02H to each byte.

3. LED Blinking:
- Blink LEDs connected at P2, 20 times, with a delay of 0.5s between each blink. Assume xtal freq = 11.0592MHz. Use Timer 0 in mode 1 to generate the delay.

4. Serial Data Transfer:
- Serially transfer of words continuously, assume 8-bit data, 1 stop bit.

5. LCD Interface:
- Interface an LCD with an 8051 microcontroller and display "Hello World!"

Ideal Skills and Experience:
- Proficiency in 8051 assembly language
- Experience with microcontroller programming
- Familiarity with LCD interfacing and timer operations
- Knowledge of arithmetic operations in assembly language

Please provide code and proteus simulation for all
