The Valgrind distribution has multiple tools. The most popular is the memory checking tool (called Memcheck) which can detect many common memory errors such as:
*
touching memory you shouldn t (eg. overrunning heap block boundaries)
*
using values before they have been initialized
*
incorrect freeing of memory, such as double-freeing heap blocks
*
memory leaks.
Address book helps you look up your addresses from the system tray.
It is quite useful in that way 慶ause it stays out of the way and is
easily accessible when needed. Double clicking on any URL will start
the default web browser and take you to that URL. Double clicking on
the phone number will dial that number. Every column supports
sorting and can be customized to your needs. Preview will display
the notes associated with each record.
This program can also import Comma Separated Values (*csv) text files
of Outlook Express.
很多嵌入式系統(tǒng),特別是應(yīng)用于圖像處理與高速數(shù)據(jù)采集等場合的嵌入式系統(tǒng),都需要高速緩存大量的數(shù)據(jù)。DDR(Double Data Rate,雙數(shù)據(jù)速率)SDRAM由于其速度快、容量大,而且價格便宜,因此能夠很好地滿足上述場合對大量數(shù)據(jù)緩存的需求。但DDR SDRAM的接口不能直接與現(xiàn)今的微處理器和DSP的存儲器接口相連,需要在其間插入控制器實現(xiàn)微處理器或DSP對存儲器的控制。
三次樣條插值程序。編譯運行本程序后,程序會彈出窗口及問句:“input the number of intervals:”,輸入插值的次數(shù)即可,程序?qū)⒌玫降拇螖?shù)保存在變量int n中。如果輸入的插值次數(shù)正確(n>=2),程序會顯示下一語句:"input the value of the variable:",此時輸入插值點即可,程序?qū)⒌玫降牟逯迭c保存在變量double v中。若插值點正確(v>=0&&v<=6),則程序?qū)⑤敵霾逯到Y(jié)果。
