Calculating the FIFO depth is a common problem in the design FIFO. Common sense tells us that when the read rate is slower than the write rate, the FIFO can be used as a buffer element or queue in the system. The size of the FIFO therefore basically implies the capacity of the required cache data, which depends on the rate at which the data is read and written. According to statistics, the system's data rate depends on the system's load capacity. So in order to ensure the FIFO size, we need to c

1. Calculation formula for the next day's bid price: Buy forecast = Open today + (today close-open today)/2 Note: The premise of calculating the bid according to this method is that the stock prices are rising today, and the candlestick is paid by the Yang Line.For example: If a stock open price is 10 yuan, close price is 10.8 yuan, then the next day's bid calculation should be 10.8-10/2=10.40 yuan. As the

: Number of users using the System x (5%~20%). There is no need to stick to the calculated results for this formula, because the number of concurrent users will be slightly larger for the system to be extended, unless the maximum number of concurrent users that the system can withstand is tested. For example: Your system supports 10,000 user access, Calculation formula of concurrent user number System users: The number of system rated users, su

Opencascade Curve Length Calculation [Email protected] Abstract.The natural parametric equations of a curve are parametric equations that represent the curve in terms of a coordinate-independent parameter, generally arc length S, instead of an arbitray variable like T or U. according to the natural equations, the curve length is the integration of the curve parametric equation's derivation. so the Core Algorithm for curve length

Generally, you need to obtain the current date and calculate some other dates. For example, your program may need to determine the first or last day of a month. Most of you probably know how to divide the date (year, month, day, etc.), and then simply use the split year, month, day, and so on to calculate In various date calculation methods of MSSQL Server, you usually need to obtain the current date and calculate some other dates. For example, your p

The Calculation of arithmetic expressions in a computer is implemented through stacks. This section first discusses two Representation Methods of arithmetic expressions, namely, the infix representation and the suffix representation. Then, it discusses the algorithm for evaluating the suffix expression. Finally, it discusses the algorithm for converting an infix expression to a suffix expression. 1. Two arithmetic expressions Generally, the written ar

images. To calculate similarity, some features must be abstracted, such as blue sky, white clouds, and green grass. Common image features include color features, texture features, shape features, and spatial relationship features. Color features are the most commonly used, including histograms, color sets, color moments, aggregate vectors, and associated graphs. A Histogram can describe the global distribution of colors in an image, which is easy to understand and implement. Therefore, it is us

Calculation of skeleton movement accumulation Transformation Next we will further consider the bone movement. The most typical method to describe a bone movement is to break down its motionCompared with its local coordinate systemRotation and translation (usually first rotat

　　Preface Histogram is a very important tool in computer vision. opencv provides many functions related to histogram processing. The most basic function is to calculate the histogram function calchist (). The histogram is also introduced in the previous blog: opencv (4) of basic learning notes: histogram usage learning. However, in my research, we need to calculate the one-dimensional histogram feature of multiple images, and each image should have its own mask matrix, and start to think of calc

1. Summary TCP Header verification and calculation: TCP Header + TCP Data + TCP pseudo header. The TCP checksum overwrites the TCP header and TCP data, while the checksum in the IP header only overwrites the IP header and does not overwrite any data in the IP datagram. The pseudo-header is used to increase the TCP checksum error checking capability. For example, it checks whether the TCP packet is received incorrectly (the destination IP address) and

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,
