摘 要 文章以空間監控系統為背景,深入研究了JPEG圖像壓縮標準的實現方法,并基于FPGA對其進行了實現和優化。文中給出了詳細的實現方法和優化過程,測試表明達到了很好的效果。 簡單介紹了有損靜態圖像壓縮當前有兩種比較流行的標準JPEG和JPEG2000。說明了用JPEG方法壓縮的原因。 介紹JPEG基本原理：JPEG對灰度圖像的壓縮處理過程主要包括:圖像分割,離散余弦變換(DCT),量化(Quantization),“Z”形排序(Zigzag Scan),差分脈沖編碼調制(DIFFERENTIAL Pulse Code Modulation,DPCM)對直流系數(DC),行程長度編碼(Run-Length Encoding,RLE)對交流系數(AC),霍夫曼(Huffman)編碼等。 JPEG標準的特點是離散余弦變換。 比較詳細介紹壓縮系統的構成和實現。實現提及步驟， JPEG壓縮模塊設計和編碼模塊實現細節。

This contribution provides functions for finding an optimum parameter set using the evolutionary algorithm of DIFFERENTIAL Evolution. Simply speaking: If you have some complicated function of which you are unable to compute a derivative, and you want to find the parameter set minimizing the output of the function, using this package is one possible way to go.

The TJA1040 is an advanced high speed CAN transceiver for use in automotive and general industrial applications. It supports the DIFFERENTIAL bus signal representation described in the international standard for in-vehicle high speed CAN applications (ISO11898). CAN (Controller Area Network) is the standard protocol for serial in-vehicle bus communication, particularly for Engine Management and Body Multiplexing. The TJA1040 provides a Standby mode, as known from its functional predecessors PCA82C250 and PCA82C251, but with significantly reduced power consumption. Besides the excellent low-power behavior the TJA1040 offers several valuable system improvements. Highlights are the absolute passive bus behavior if the device is unpowered as well as the excellent EMC performance.
