Explanation:

VLIW Architecture and Parallelism:

VLIW (Very Long Instruction Word) architecture is designed to achieve parallelism by packing multiple operations into a single instruction word. By doing so, VLIW processors can execute these operations simultaneously without the need for complex hardware to detect dependencies between instructions.

Approach to Achieve Parallelism:

MIMD (Multiple Instruction, Multiple Data) is the approach followed by VLIW architecture to achieve parallelism. In MIMD architecture, multiple processors or processing elements execute different instructions on different sets of data simultaneously. Each processing element operates independently, allowing for true parallelism in task execution.

Comparison with other Architectures:

- SISD (Single Instruction, Single Data): In SISD architecture, a single processor executes a single instruction on a single piece of data at a time, lacking parallelism.
- MISD (Multiple Instruction, Single Data): In MISD architecture, multiple processors execute different instructions on the same data stream, which is not commonly used due to limited practical applications.
- SIMD (Single Instruction, Multiple Data): In SIMD architecture, a single instruction is executed on multiple pieces of data simultaneously, which is different from VLIW's approach of packing multiple operations in a single instruction word.

Conclusion:

Overall, VLIW architecture's MIMD approach allows for efficient utilization of resources and high levels of parallelism, making it suitable for tasks that require multiple operations to be executed concurrently.
