Study Notes
Instruction Set in Microprocessors
- An instruction set is a collection of instructions that a microprocessor can execute, defining its operation.
- It includes various categories such as data manipulation, control flow, input/output operation, and arithmetic functions.
- Each instruction corresponds to a specific command that tells the processor what actions to perform.
8085 Microprocessor Characteristics
- The 8085 microprocessor is an 8-bit processor capable of executing a wide range of instructions.
- It has a 16-bit address bus, allowing it to access up to 64KB of memory.
- The 8085 features five 8-bit registers: B, C, D, E, H, and L, along with a 16-bit Stack Pointer and Program Counter.
- It operates in a clock speed range of 3 MHz to 6 MHz, facilitating execution of instructions efficiently.
Copying Data Instructions
- The instruction MOV is used to copy data from one register to another, allowing for data manipulation without affecting memory.
- To copy data from a memory location to a register, the LDAX instruction is utilized, loading data directly into the register from memory.
- The instruction STA is used to store accumulator content into a specific memory location, facilitating data storage.
