松耦合多处理器系统:
它是一种多处理系统,其中有分布式内存而不是共享内存。在松耦合的多处理器系统中,数据速率比紧耦合的多处理器系统低。在松耦合的多处理器系统中,模块通过 MTS(消息传输系统)网络连接。
紧耦合多处理器系统:
它是一种多处理系统,其中有共享内存。在紧耦合的多处理器系统中,数据速率比松耦合的多处理器系统高。在紧耦合多处理器系统中,模块通过 PMIN、IOPIN 和 ISIN 网络连接。
让我们研究松耦合和紧耦合多处理器系统之间的区别:
S.NO | Loosely Coupled | Tightly Coupled |
---|---|---|
1. | There is distributed memory in loosely coupled multiprocessor system. | There is shared memory, in tightly coupled multiprocessor system. |
2. | Loosely Coupled Multiprocessor System has low data rate. | Tightly coupled multiprocessor system has high data rate. |
3. | The cost of loosely coupled multiprocessor system is less. | Tightly coupled multiprocessor system is more costly. |
4. | In loosely coupled multiprocessor system, modules are connected through Message transfer system network. | While there is PMIN, IOPIN and ISIN networks. |
5. | In loosely coupled multiprocessor, Memory conflicts don’t take place. | While tightly coupled multiprocessor system have memory conflicts. |
6. | Loosely Coupled Multiprocessor system has low degree of interaction between tasks. | Tightly Coupled multiprocessor system has high degree of interaction between tasks. |
7. | In loosely coupled multiprocessor, there is direct connection between processor and I/O devices. | While in tightly coupled multiprocessor, IOPIN helps connection between processor and I/O devices. |
8. | Applications of loosely coupled multiprocessor are in distributed computing systems. | Applications of tightly coupled multiprocessor are in parallel processing systems. |
