Calculation Formula description The backboard bandwidth of A vswitch is the maximum amount of data that can be transferred between the vswitch interface processor or interface card and the data bus. The backboard bandwidth indicates the total data exchange capability of a vswitch. The unit is Gbps. It is also called the switching bandwidth. The bandwidth of A vswitch ranges from several Gbps to hundreds of Gbps. The higher the bandwidth of A vswitch,

also used in led floodingin the dynamic circuit. Figure one is a practical led driver circuit with capacitive buck: Note that most application circuits do not have a varistor or transient voltage suppressor transistor connected ,It is recommended to connect, because the varistor or the transient voltage suppressor transistor can effectively discharge the mutation current in the moment of voltage mutation (such as lightning ﹑, large electric equipment start, etc.) toprotection of two-level and o

Inverse calculation: Write a function to convert an integral type to a binary formInverse calculation problem, recursion is simpler than loopAnalysis: Need to understand that the last digit of the odd binary is 1, even the binary last one must be 0, associative memory, this and the parity of the integer is consistent, 1 itself is odd, 0 itself is an even number.decimal integers are converted to binary integ

I. Toolbar method,1. Right-click the blank area in the toolbar and select "table and border" in the pop-up menu.2. Move the cursor to the result output cell, and then click the find button to add the result immediately.3. Although this method is fast, it can only sum and cannot perform other function operations. By default, the formula {= SUM (LEFT)} is used to calculate the SUM of all cells on the LEFT of the cell where the cursor is located. If the SUM of all cells on the right of th

This article only discusses the implementation methods of inventory and database age from a technical point of view. These are my summary in my work and I will discuss them with you. 1. Oracle inventory algorithm. Oracle Applications provides the MTL_ONHAND_QUANTITIES_DETAIL table for inventory calculation. Developers only need to group and sum the tables as required to obtain the inventory quantity. This quantity is the quantity we query in the syst

When executing the "Apply image" and "compute" commands, we tend to mix two channels, not knowing that PS also allows the selection to be used as a channel, but more often than not, we think the hybrid channel It's just a matter of two channels, so it ignores the existence of a constituency. If you can make the most of the existing selections in the image, you may find more solutions for selecting the image. In this case, We use the mixed results of the selection and the channel when we choose

Using channel calculation and gradient mapping to beautify beauty in detail The same is the use of channels and calculation of skin and whitening, but the author later added a gradient map to enhance skin color contrast, you can better highlight skin texture. Channel and calculation whitening is very classic, if you are not familiar with, you can seriously study

The process of using matplotlib for scientific computing data can be simple or complex, and is usually determined by requirements. For example, simple to get two-dimensional data, according to the X coordinates to draw the corresponding y-coordinate values, which belong to matplotlib very basic function. From a general technical point of view, in order to achieve scripting code reuse, we should use object-oriented or modular programming method to write the data Processing program code, this tuto

In the previous article (WEBRTC Audio-related Neteq (ii): Data structure) Neteq the main data structures, to understand the mechanism of Neteq lay a good foundation. This article is mainly about how the RTP packets received from the network in the MCU are put into packet buffer and taken out from packet buffer, as well as the calculation of the network delay value (optbuflevel) and the jitter buffer delay value (bufflevelfilt). Let's see how RTP voice

For wage calculation, three aspects need to be configured: wage calculation cycle, wage type, and wage item. Configure the wage calculation cycle as follows:1. Define period Parameters The period parameter table shows the wage accounting frequency. Topic Set period Parameters Menu path SAP User-based implementation guide → payroll: China

Before starting the text, I would like to thank Unitedstack Engineer Zhu Rongze for his great help and careful advice on this blog post. This paper makes a more explicit analysis and elaboration on the calculation method of Ceph reliability (https://www.ustack.com/blog/build-block-storage-service/) for Unitedstack company at the Paris summit. For the interests of this topic friends to discuss, research, the article if there is inappropriate, but also

Preface This article will simply write down the calculation method of the parameters on the convolution neural network, and then compute the parameters of each common neural network. One is to strengthen the understanding of the network structure, on the other hand, the magnitude of the network parameters have a general understanding, can also be used as a memo, lest want to know when to calculate. parameter calc
