針對UHF讀寫器設計中，在符合EPC Gen2標準的情況下，對標簽返回的高速數(shù)據(jù)進行正確解碼以達到正確讀取標簽的要求，提出了一種新的在ARM平臺下采用邊沿捕獲統(tǒng)計定時器數(shù)判斷數(shù)據(jù)的方法，并對FM0編碼進行解碼。與傳統(tǒng)的使用定時器定時采樣高低電平的FM0解碼方法相比，該解碼方法可以減少定時器定時誤差累積的影響；可以將捕獲定時器數(shù)中斷與數(shù)據(jù)判斷解碼相對分隔開，使得中斷對解碼影響很小，實現(xiàn)捕獲與解碼的同步。通過實驗表明，這種方法提高了解碼的效率，在160 Kb/s的接收速度下，讀取一張標簽的時間約為30次/s。 Abstract: Aiming at the requirement of receiving correctly decoded data from the tag under high-speed communication which complied with EPC Gen2 standard in the design of UHF interrogator， the article introduced a new technology for FM0 decoding which counted the timer counter to judge data by using the edge interval of signal capture based on the ARM7 platform. Compared with the traditional FM0 decoding method which used the timer timed to sample the high and low level， the method could reduce the accumulation of timing error and could relatively separate capture timer interrupt and the data judgment for decoding， so that the disruption effect on the decoding was small and realizd Synchronization of capture and decoding. Testing result shows that the method improves the efficiency of decoding， at 160 Kb/s receiving speed， the time of the interrogator to read a tag is about 30 times/s.

同步技術是跳頻通信系統(tǒng)的關鍵技術之一，尤其是在快速跳頻通信系統(tǒng)中，常規(guī)跳頻通信通過同步字頭攜帶相關碼的方法來實現(xiàn)同步，但對于快跳頻來說，由于是一跳或者多跳傳輸一個調(diào)制符號，難以攜帶相關碼。對此引入雙跳頻圖案方法，提出了一種適用于快速跳頻通信系統(tǒng)的同步方案。采用短碼攜帶同步信息，克服了快速跳頻難以攜帶相關碼的困難。分析了同步性能，仿真結果表明該方案同步時間短、虛警概率低、捕獲概率高，同步性能可靠。 Abstract: Synchronization is one of the key techniques to frequency-hopping communication system， especially in the fast frequency hopping communication system. In conventional frequency hopping communication systems， Synchronization can be achieved by Synchronization-head which can be used to carry the Synchronization information， but for the fast frequency hopping， Because modulation symbol is transmitted by per hop or multi-hop， it is difficult to carry the correlation code. For the limitation of fast frequency hopping in carrying correlation code， a fast frequency-hopping Synchronization scheme with two hopping patterns is proposed. The Synchronization information is carried by short code， which overcomes the difficulty of correlation code transmission in fast frequency-hopping. The performance of the scheme is analyzed， and simulation results show that the scheme has the advantages of shorter Synchronization time， lower probability of false alarm， higher probability of capture and more reliable of Synchronization.

This application note describes the implementation of a two-dimensional Rank Order filter. Thereference design includes the RTL VHDL implementation of an efficient sorting algorithm. Thedesign is parameterizable for input/output precision, color standards, filter kernel size,maximum horizontal resolution, and implementation options. The rank to be selected can bemodified dynamically, and the actual horizontal resolution is picked up automatically from theinput Synchronization signals. The design has a fully synchronous interface through the ce, clk,and rst ports.
