Study Notes
Machine Code and Instruction Set Architecture
- Machine code consists of binary instructions that directly control the CPU.
- In the contemporary marketplace, x86-64 computers dominate the market.
Instruction Execution
- Each instruction in machine code causes the CPU to perform a specific action, such as arithmetic, logical operations, or memory access.
Instruction Set Architecture (ISA)
- The notion of an Instruction Set Architecture (ISA) defines and specifies the syntax and semantics of machine code instructions.
Early CPUs and Backwards Compatibility
- Early CPUs had variant instruction sets, which might break backwards compatibility with each new CPU released.
Interpreter Strategies
- An interpreter like Perl or Python uses a strategy of executing source code line by line, without prior compilation.
Interpreter Examples
- BASIC is an example of a interpreter that uses a strategy of executing source code line by line, without prior compilation.
- Java is an example of a interpreter that uses a strategy of compiling source code into an intermediate form, then executing it.
Interpreter Function and Role
- The primary function of an interpreter in computer science is to execute source code directly, without prior compilation.
- The role of an interpreter in the execution of source programs compiled ahead of time is to execute the compiled intermediate form, such as bytecode.
