the additional power and area overhead
时间: 2024-02-03 20:01:51 浏览: 31
The additional power and area overhead refers to the increase in power consumption and silicon real estate required when implementing a certain feature or function in a chip or system. This overhead is usually incurred when adding more complex circuits, additional logic gates, or larger memory blocks to a design. The increase in power consumption and silicon area can impact the overall performance, power efficiency, and cost of the system. Designers must carefully balance the trade-offs between functionality, performance, and cost when deciding whether to add new features to a design.

Otherwise, when the data is offloaded for edge execution (xti = 1), we denote Pit as the transmit power constrained by the maximum power Pt ≤ Pmax and τtT as the amount of time iii allocated to the ith WD for computation offloading. Here, τit ∈ [0, 1] and Ni=1 τit ≤ 1. The energy consumed on data offloading is Eit,O = PitτitT. Similar to [4] and [8], we neglect the delay on edge computing and result downloading such that the amount of data processed at the edge within the time frame is Dt =WτitTlog 1+Pithti=WτitTlog 1+Eit,Ohti, ∀xt =1, (2) i,O vu 2 N0 vu 2 τitTN0 i where vu ≥ 1 denotes the communication overhead and N0 denotes the noise power.,Diot是怎么得到的
在给定的模型中,Diot是指在第i个设备上进行边缘计算的数据量。根据公式(2),可以看出Diot是由W、τit和Pit共同决定的。其中,W是设备需要进行计算的数据量,τit是设备在一定时间内用于边缘计算的时间比例,Pit是设备在进行数据离载时所能使用的最大传输功率。公式(2)中的log项是通过信噪比和传输功率计算得出的数据传输速率。因此,Diot可以根据这些参数计算出来。
GC overhead limit exceeded
GC overhead limit exceeded is an error message that occurs when the Java Virtual Machine (JVM) is unable to allocate enough memory for garbage collection (GC) to clean up the heap. This error occurs when the JVM spends too much time performing garbage collection and not enough time executing application code.
The GC overhead limit is a threshold set by the JVM to prevent it from spending too much time on garbage collection. When the limit is reached, the JVM throws the "GC overhead limit exceeded" error and terminates the application.
To resolve this error, you can try the following:
1. Increase the heap size of the JVM using the -Xmx flag.
2. Increase the GC overhead limit using the -XX:GCTimeLimit and -XX:GCHeapFreeLimit flags.
3. Optimize your application code to reduce memory usage.
4. Identify and eliminate memory leaks in your code.
5. Use a profiler tool to analyze the memory usage of your application and identify areas that need optimization.
6. Consider upgrading to a newer version of Java that has improved garbage collection performance.
