main memory of 100 to 300 cycles, you can see this multilevel cache + main memory structure has opened a clear level, in their respective design can have different focus, Complement each other to improve the performance of the entire system.Cache research has been going on for a long time, until today is still a hot spot for research. But the previous research object is this level of cache between CPU and main memory, and now the research object is a

The software uses a double preview window, you can adjust the compression rate and real-time to see the image compression quality. It supports Adobe Photoshop PSD files, Hdr/raw imports, and other supported formats including common formats such as jpg/gif/png.Write in the back:Anyone who has built a station or played an independent blog/personal site is sure to

A professional website to get the trust and confidence of most people, how can you get rid of your website rustic, to create a professional? Here is a 12 point design essentials, consider in a professional website design. 1. First Impressions We all know that first impressions are very important. It has always been a big factor in retaining readers and attracti

Reading notes: Multi-threaded programming Essentials: 1. There are main and working memory points in multiple threads, and in the JVM there is a master memory that is dedicated to all threads sharing data, while each thread has his own private working memory, the main memory and the working memory decibels in the JVM's stack and heap areas. 2. The state of the thread has ' ready ', ' Running ', ' sleeping ', ' Blocked ', and ' waiting ' several states

sending the request to the bus! What if the system's hardware MMU is fully used? Can you make use of its TLB? If not, what's the point? Do you know what a TLB hit means? Do you know that most of the MMU addressing operations are not directly to the page table but are basically hit in the TLB? TLB is a kind of cache! Therefore, the simulation of the MMU is not the fundamental purpose, the use of the cache is kingly!We know that the CPU Cache (including TLB) can be hit at a considerable frequency

hierarchical index to establish the mapping of the IPV4 address to the next-hop index, consider how many of these mappings will be there altogether? All the IPv4 address, then is 4G map, calculate the mapping table, the next hop table, a total of more than 4G of memory available ... Isn't this a space change time? Multilevel mapping table does not save space-instead it adds management overhead, it only adapts to sparse indexes, and we know that the destination IPv4 address is not a sparse index

Chbihov analog filterThe given technical indicators are:It is known that the cut-off frequency of the band is fp = 5 kHz, the maximum attenuation of the band is Delta C Based on the above technical indicators, the design and implementation of the kV 1 low-pass filter are as follows.WP = 5000*2 * PI;Ws = 12000*2 * PI;Rp = 2;Rs = 30;[N, Wn] = cheb1ord (WP, WS, RP, RS, 's'); % calculate the order and cut-off f

two parameters: cutoff frequency, orderExample: design of a Butterworth low-pass filter up to 75Hz, to 150Hz attenuation to 30dBStep One: Determine the order, according to According to the formula: A = W1 (maximum attenuation frequency)/w2 (up to frequency) a = 150hz/75hz = 2;When a = 2, the attenuation multiplier is 30dB, according to the order number is 5 order.----------------------------------------------------------------------------------------

cache is kingly!We know that the CPU Cache (including TLB) can be hit at a considerable frequency because of the locality of memory addressing! Does this locality exist for IP addresses? Imagine that multiple packets belonging to a single data stream will continue to pass through, and the packet error peaks of different data streams will know that the principle of locality is a universal principle. Traffic engineering on the core path is path-based, and QoS is application-based, and this classi
