Final answer:
The syntax of MIPS is rigid because it follows a strict set of rules for the position and order of binary bits representing instructions. This ensures correct and efficient execution.
Step-by-step explanation:
The syntax of MIPS (Microprocessor without Interlocked Pipeline Stages) is considered rigid because it follows a strict set of rules for how instructions should be written. This rigidity ensures that the instructions are executed correctly and efficiently by the processor.
In MIPS, each instruction is represented by a specific combination of binary bits, known as the opcode. The position and order of these bits must be followed precisely. Any deviation from the syntax can result in incorrect instruction execution or even system crashes.
For example, in MIPS, the ADD instruction has the opcode 000000 and the function code 100000. If you were to write ADD with a different opcode or function code, the processor would not recognize it as a valid instruction and would generate an error.
