With the wide application of LSI, the control logic is more and more integrated on the motherboard, and its logic correctness is more and more difficult to judge by measurement. It can

1: Due to work, I have been engaged in the development of 2 * 36port Expander in LSI for the past few months. It mainly parses and processes the SSP, SMP, and SES command protocols in SAS.
The SDK of LSI uses the threadx operating system. The kernel of its chip is ARM920T, which provides the SAS protocol processing function at 920t. I personally feel that the Code style is not good.

But I already said at the beginning that the machines in the cluster have the same configuration and the deployed programs have the same rsync as before. Is the hard disk broken?
I have to check the problem with the O M personnel. The final conclusion is:
Sdb is a dual-disk RAID 1 with a RAID card of "LSI Logic/Symbios Logic SAS1068E" and no cache. Nearly 400 of IOPS has reached the hardware limit. The raid cards used by oth

However, when using a search table, it may be less than 200. Therefore, it is necessary to make more detailed analysis to estimate the number of equivalent FPGA doors.

Beginner STM32, feel the most egg pain is its clock system, every time see its clock tree is a bit dizzy, although read a lot of this information, even has written a lot of STM32 module code, did some small project, but always still on this piece of vague, indefinitely, So I want to write a little bit of my knowledge of it, step-by-step, until the day of full straightened out, (these things are not original, just want to help themselves understand)In STM32, there are five clock sources for HSI,

SVD is a powerful tool for extracting information that we can use to represent raw datasets with a small number of datasets, which is actually the removal of noise and redundant information.Implicit semantic indexingSVD is the earliest application of information retrieval, we call the SVD method as the recessive semantic index (LSI), in LSI, a matrix is composed of documents and words, when the application

Stanford ml Public Lesson Note 15In our last note we talked about PCA (principal component analysis).PCA is a kind of direct dimensionality reduction method.
