The multifunction image network monitor system based on Ethernet adopt network control chip LAN91C111 as the communication interface as well as the dedicated image processing chip TMS320C6211B and complex programmable logic device EPM7256AE to complete sampling and processing of the real-time digital image signals.
A digital acquisition interface module for radar signals is described which is realizated by using CPLD M4A5-128/64 and DSP TMS320VC5402.The functions and specifications of main devices used are introduced.
So Programmable Logic Device (PLD) as Field Programmable Gates (FPGA) and Complex Programmable Logic Device (CPLD) are used widely. The advanced technology of hardware designs using these Programmable Logic Devices develope quickly.
With rapid developments of system on chip (SOC), programmable logic devices (PLD), including complex programmable logic device (CPLD) and field programmable gate array (FPGA), can support in-system programmability (ISP) and become more popular in the world.
随着片上系统(SOC,System On Chip)时代的到来,包括复杂可编程逻辑器件(CPLD,Complex Programmable Logic Device)和现场可编程门阵列(FPGA,Field Programmable Gate Array)的可编程逻辑器件,具有系统内可再编程的独特优点,应用越来越广泛。
This paper briefly describes the structure of programmable logic devices (CPLD/FPGA), the design flow of Foundation software, the characteristics of hardware description language VHDL and particularly introduces the ARINC429 specifications, the design of ARJNC429 bus interface.
It was shown that PLA2 deacetylates the glycerol residue at position 2, PLC is inactive, and PLD hydrolyzes the phosphatidylnucleosides to give free nucleosides.
It was caused by an insertion of the T region of vector pLD3 used for transformation of germinating seeds when creating the collection of insertion mutants.
The mutation under study showed incomplete dominance and represented a single insertion of the T region of pLD3 vector used for transformation of germinating seeds to the plant genome during the creation of the collection.
The genomes of the transgenic plants contain insertions of T-DNA of the vector plasmids pLD3 or pPCVRN4.
The mutants were selected from a collection of transgenic plants that had genomes carrying a T-DNA insertion of plasmid vectors pLD3 and pPCVRN4; the collection was created earlier via agrobacterial transformation of germinating seeds.
Starting with description of application specific integrated circuit (ASIC), this lecture chiefly describes the principle and architecture of programmable logic devices(PLD).As viewed from application, this lecture Introduces the architecture and feature of general array logic(GAL) devices, which emphasizes upon the programming technique of PLD. Finally, several examples of application of PLD are given.
Starting with deseription or application specitic IC (ASIC) ,this lecture chiefly describes the principle and architecture of programmable logic devices (PLD). As viewed from applications, this lecture introduces the architecture and feature of general array logic(GAL)devices, which emphasizes upon the programming technique of PLD. Finally, several examples of application of PLD are given.
The first generation of programmable logic devices(PLDs) allowed you to pack five or ten TTL devices into one package. The latest programmable devices, FPGA, can replace about 40 to 400 small-scale integrated circuits. The paper introduces the basic architecture and main perfermance on four types of programmable gate arrays, and the programming technology by which you can design your circuits with these chips.
