Because the lower layer contains more image detail, using a feature map of the lower layer of the network (shallow layer) can enhance the semantic information and improve the prediction effect. anchor’s design The size of the anchor in the SSD is not uniformly scaled according to the size of the feature map. Instead, a linear interpolation transformation is set manually:  set the following values for aspect ratios of anchor: According to a_r, anchor width is calculated as:disks SSD so for each grid position, a total of 6 anchor pre-check boxes are generated. in addition, the center coordinate of the anchor is: compared to the previous practice, the anchor size shapes in the SSD are richer and can better match the objects in the image. box matches after generating the anchor preselector box, first for each ground truth box, select and it has the largest IOU The pre-selection box (written as Jaccard overlap) is matched, labeled as a positive sample, for training.

ram ddr4 vs SSD

ram ddr4 & SSD external hard disk SSD OEM ram ddr4 Chinese a long-standing view on the Internet: SSD hard disk cannot partition. the rationale can be summarized as follows: SSD exists read-write equalization algorithmram ddr4,” Partitioning will cause a portion of storage space to be excluded from read-write equalization ram ddr4, which reduces SSD lifetime. but recently when tossing a dual system I wondered why all the discussions on the dual system have not talked about the problem of “partition performance reduction”? Obviously you can’t install a dual system without partitioning (WSL does not count) so I searched and found the following post: which has a detailed explanation, as well as some corresponding more specific information, interested students can click into it themselves. for students who are too lazy to read the original text, I will summarize the views roughly: 1, partitioning does not have any effect on the SSD, because the SSD isolates the physical location, the operating system does not know the physical location of the file at all, as long as you read and write the file, its distribution may change randomly. Therefore, there is no such thing as “the separated area will not be manipulated”. Partitioning is just an “illusion” of the operating system, and you can even deliberately leave an unpartitioned space when partitioning, which can extend the life

Whether it is a manufacturer of the whole machine online or a user who buys accessories to assemble a computerssd 500gb, basically SSD as the first choice, and the opposite hard disk drive ( HDD for short) is usually treated as a warehouse disk. in order to facilitate understanding, we use the form of a table to briefly distinguish the similarities and differences between the two hard disks (taking the 2.5-inch product as an example), and then mainly for the SSD to make some instructions. the above figure, it can be seen that in addition to price factors, SSD basically shows a comprehensive crushing trend. This is mainly caused by the different ways in which the data is stored.ssd 500gb interlude, we get to the point. For most PC hardware, there is never more than one industry-approved classification standard. Only by understanding SSDs from different latitudes can we have a deeper understanding of this part. according to this latitude can be divided into three categories of common SSDs: SATA interface, M.2 interface, PCIE interface. the conclusions obtained below are based on the control variables (interface types), and all other conditions are the same by default. SATA interface of the

Three 2.5″ HDD Tests solid disks SSD OEMddr3 mechanical hard drives for everyone ddr3 + 8618750919058, although SSDs is decreasing year by year ddr3 , but in terms of capacity / price ratio, there is still a long way to go from the mechanical hard disk. Although HDD has the advantage of large capacity, but now the hard disk storage density is getting higher and higher, the head is too close to the platter, and the current hard disk is becoming more and more fragile, and it is often seen that the mobile hard disk and notebook hard disk are damaged. For 3.5-inch mechanical hard disks, because they are fixed in the chassis or NAS or hard disk boxes for many years, they are not often moved, so the problem of shock resistance is not too serious, and the failure rate is not high. Most notebooks are equipped with HDD mechanical hard disks as standard, and daily work often uses removable hard disks, these two use scenarios inevitably need to be moved frequently, so the shockproof problem of 2.5-inch hard disks is particularly prominent. many years ago, ThinkPad notebooks have a very eye-catching function called APS Active Hard Disk Protection System (ThinkVantage Active Protection System), the principle is that the notebook has a built-in acceleration sensor,

Соответствие длины линии является еще одним важным звеном. Давайте рассмотрим, что основным принципом маршрутизации DDR, согласования длины строки является: адрес, сигнал управления / команды и тактовая частота должны делать одинаковую длину. Сигнал данных имеет ту же длину, что и DQS. Почему вы должны ждать длины? Люди скажут, что необходимо позволить одному и тому же набору сигналов достичь принимающего конца в одно и то же время, чтобы принимающий чип мог обрабатывать эти сигналы одновременно. Итак, когда тактовый сигнал и адрес достигают принимающего конца одновременно, каково соответствие формы сигнала? Давайте посмотрим на конкретную форму сигнала с помощью моделирования. установить следующие каналы для имитации адресного сигнала и тактового сигнала DDR3 соответственно. для удобства расчета, мы предполагаем, что тактовая частота DDR составляет 500 МГц, так что скорость соответствующего адресного сигнала должна составлять 500 Мбит/ с, здесь мы должны понимать, что хотя DDR является двойной скоростью, но для адреса / управляющего сигнала это все еще одна скорость. Давайте посмотрим на форму сигнала, в случае адреса и часов имеют точно такую же длину, принятая форма сигнала стороны адреса и данных такая, как показано на рисунке 2 ниже, красный представляет адресный сигнал, а зеленый представляет тактовый сигнал. над формой

Итак, какова связь между сигналами данных и DQS? Мы знаем, что твердый диск+8618750919058“, DDR по сравнению с обычной SDRAMтвердый диск+8618750919058,” Скорость чтения в два раза выше, чем у обычной SDRAM, как это понять? Первоначально SDRAM запускался восходящим или нисходящим краем при записи или чтении данных, поэтому обратите внимание, что это только восходящий или нисходящий край, а не восходящие и опускающиеся края, которые действительны одновременно. Если тактовая частота составляет 800 МГц, соответствующая скорость передачи данных составляет 800 Мбит / с. Но сигнал данных DDR в два раза быстрее, если частота DQS составляет 800 МГц, то скорость сигнала данных должна составлять 1600 Мбит/с. Давайте посмотрим на это через конкретные примеры моделирования. Рисунок 1 Схема моделирования DQ и DQS канала моделирования, как показано на рисунке выше, драйвер и приемник являются моделью IBIS компании по производству чипов, а форма сигнала моделирования выглядит следующим образом: Рисунок 2 Формы сигналов моделирования DQ и DQS Мы генерируем глазные диаграммы сигналов DQS и DQ одновременно и наблюдаем их в одном окне, результаты следующие: Рисунок 3 Диаграммы глаз DQ и DQS Здесь автор первоначально хотел смоделировать временное соответствие между DQS и DQ, когда DDR записывал операции.

SSD was born in the 1970s, the earliest SSD used RAM, RAM power-down data will be lost, the price is particularly expensive. Later, flash-based SSDs appeared, and after flash memory power-downs, data was not lost, and flash SSDs slowly replaced RAM SSDs. At this time, HDD disks have occupied most of the storage market. By the beginning of this century, due to the continuous advancement of the process, SSDs have won great development, capacity and performance continue to increase, and prices continue to decline. HDD in the process and technology has been difficult to have a breakthrough, SSD in performance and capacity is still breaking through, relative to the shrinking HDD market, whether it is the rapid popularization of SSD in the enterprise market or the consumer market, SSD market share has been expanding. It is believed that in the near future, SSDs will replace HDDs as mainstream storage devices in the field of online storage and become the mainstream devices of software-defined storage. in the mode of operation, HDD uses disks,
