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.

關(guān)于FPGA流水線設(shè)計(jì)的論文 This work investigates the use of very deep pipelines for implementing circuits in FPGAs, where each pipeline stage is limited to a single FPGA logic element (LE). The architecture and VHDL design of a parameterized integer array multiplier is presented and also an IEEE 754 compliant 32-bit floating-point multiplier. We show how to write VHDL cells that implement such approach, and how the array multiplier architecture was adapted. Synthesis and simulation were performed for Altera Apex20KE devices, although the VHDL code should be portable to other devices. For this family, a 16 bit integer multiplier achieves a frequency of 266MHz, while the floating point unit reaches 235MHz, performing 235 MFLOPS in an FPGA. Additional cells are inserted to synchronize data, what imposes significant area penalties. This and other considerations to apply the technique in real designs are also addressed.

LINEINTRGAL Line Integral in a 2D Vector Field. LINEINTRGAL(X,Y,U,V,C) computes the line integral along the lines given in cell array C. X and Y define the coordinates of a rectangular grid over which U and V are defined. X and Y must be monotonic and 2D plaid as % produced by MESHGRID. X, Y, U, and V must all be the same size.

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(chǎng)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(jià)格便宜,因此能夠很好地滿足上述場(chǎng)合對(duì)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(chǔ)器接口相連,需要在其間插入控制器實(shí)現(xiàn)微處理器或DSP對(duì)存儲(chǔ)器的控制。
