The concept of the Altera Nios II embedded processor implementation inside Field Programmable Gate ARRAY [FPGA] of the CCD camera for the “Pi of the Sky” experiment is presented. The digital board of the CCD camera, its most important components, current implementation of firmware [VHDL] inside the FPGA and the role of external 8051 microcontroller is briefly described. The main goal of the presented work is to get rid of the external microcontroller and to design new system with Nios II processor built inside FPGA chip. Constraints for implementing the design into the existing camera boards are discussed. New possibilities offered by a larger FPGA for next generation of cameras are considered.

The AT24C512 provides 524,288 bits of serial electrically erasable and programmable read only memory (EEPROM) organized as 65,536 words of 8 bits each. The device鈥檚 cascadable feature allows up to four devices to share a common two-wire bus. The device is optimized for use in many industrial and commercial applications where lowpower and low-voltage operation are essential. The devices are available in spacesaving 8-pin PDIP, 8-lead EIAJ SOIC, 8-lead JEDEC SOIC, 8-lead TSSOP, 8-lead Leadless ARRAY (LAP), and 8-lead SAP packages. In addition, the entire family is available in 2.7V (2.7V to 5.5V) and 1.8V (1.8V to 3.6V) versions.

procedure senddata var i:integer commflg : Boolean begin commflg:=true for i:=1 to 8 do begin if not fcomm comml writecommdata(sendbutter,i) then begin Commflg=false break end end end (4) 接收数据 在编写基于串口的计算机工业测控时，通常需要由下位机向PC机发送数据以使PC机了解系统的测试数据或下位机的运行状态，并进而控制下位机的行为。利用Spcomm串口控件接收下位机发送的数据信息的示例代码如下： //事件驱动方式接收数据程序 procedure TForm1.CommlReceiveData(Sender:Tobject Buffer:Pointer bufferLength:Word) var receivedata:ARRAY of byte begin sleep(100) //等待100ms，保证接收到所有数据 move(buffef ,receivedata,bufferlength) //将接收缓存区中的数据转移到数组中 …… end (5) 关闭串口 在系统开发中，应注意在不使用串口时应及时关闭串口，释放系统资源，否则可能会影响系统的其它应用。关闭串口的代码如下： procedure TForm1.FormClose ( Sender TObj ect:var Action:TCIoseAction ) begin comml.StopComm end

WSNs being energy constrained systems, one major problem is to employ the sensor nodes in such a manner so as to ensure maximum coverage and connectivity with minimal or optimal number of nodes and furthermore elongate network lifetime with maximum energy utilization. The problem addressed has been tackled for 1-D linear ARRAY and further extended to 2-Dimensions as stated in the next slides.

Heapsort 1.A heap is a binary tree satisfying the followingconditions: -This tree is completely balanced. -If the height of this binary tree is h, then leaves can be at level h or level h-1. -All leaves at level h are as far to the left as possible. -The data associated with all descendants of a node are smaller than the datum associated with this node. Implementation 1.using a linear ARRAY not a binary tree. -The sons of A(h) are A(2h) and A(2h+1). 2.time complexity: O(n log n)
