The CC1101 is a low-cost sub- 1 GHztransceiver designed for very low-powerwireless applications. The circuit is mainlyintended for the ISM (Industrial, Scientific andMedical) and SRD (Short Range Device)frequency bands at 315, 433, 868, and 915MHz, but can easily be programmed foroperation at other frequencies in the 300-348MHz, 387-464 MHz and 779-928 MHz bands.CC1101 is an improved and code compatibleversion of the CC1100 RF transceiver. Themain improvements on the CC1101 include:

對(duì)象放置(Object Placement)
ISIS支持多種類型的對(duì)象，每一類型對(duì)象的具體作用和功能將在下一章給出。雖然類型不同，但放置對(duì)象的基本步驟都是一樣的。
放置對(duì)象的步驟如下(To place an object:)
1.根據(jù)對(duì)象的類別在工具箱選擇相應(yīng)模式的圖標(biāo)(mode icon)。
2. Select the sub-mode icon for the specific type of object.
2、根據(jù)對(duì)象的具體類型選擇子模式圖標(biāo)(sub-mode icon)。
3、如果對(duì)象類型是元件、端點(diǎn)、管腳、圖形、符號(hào)或標(biāo)記，從選擇器里(selector)選擇你想要的對(duì)象的名字。對(duì)于元件、端點(diǎn)、管腳和符號(hào)，可能首先需要從庫(kù)中調(diào)出。
4、如果對(duì)象是有方向的，將會(huì)在預(yù)覽窗口顯示出來(lái)，你可以通過(guò)點(diǎn)擊旋轉(zhuǎn)和鏡象圖標(biāo)來(lái)調(diào)整對(duì)象的朝向。
5、最后，指向編輯窗口并點(diǎn)擊鼠標(biāo)左鍵放置對(duì)象。對(duì)于不同的對(duì)象，確切的步驟可能略有不同，但你會(huì)發(fā)現(xiàn)和其它的圖形編輯軟件是類似的，而且很直觀。
選中對(duì)象(Tagging an Object)
用鼠標(biāo)指向?qū)ο蟛Ⅻc(diǎn)擊右鍵可以選中該對(duì)象。該操作選中對(duì)象并使其高亮顯示，然后可以進(jìn)行編輯。
This document was developed under the Standard Hardware and Reliability Program (SHARP) TechnologyIndependent Representation of Electronic Products (TIREP) project. It is intended for use by VHSIC HardwareDescription Language (VHDL) design engineers and is offered as guidance for the development of VHDL modelswhich are compliant with the VHDL Data Item Description (DID DI-EGDS-80811) and which can be providedto manufacturing engineering personnel for the development of production data and the subsequent productionof hardware. Most VHDL modeling performed to date has been concentrated at either the component level orat the conceptual system level. The assembly and sub-assembly levels have been largely disregarded. Under theSHARP TIREP project, an attempt has been made to help close this gap. The TIREP models are based upon lowcomplexity Standard Electronic Modules (SEM) of the format A configuration. Although these modules are quitesimple, it is felt that the lessons learned offer guidance which can readily be applied to a wide range of assemblytypes and complexities.

Wavelets have widely been used in many signal and image processing applications. In this paper, a new
serial-parallel architecture for wavelet-based image compression is introduced. It is based on a 4-tap wavelet
transform, which is realised using some FIFO memory modules implementing a pixel-level pipeline
architecture to compress and decompress images. The real filter calculation over 4 · 4 window blocks is
done using a tree of carry save adders to ensure the high speed processing required for many applications.
The details of implementing both compressor and decompressor sub-systems are given. The primarily analysis
reveals that the proposed architecture, implemented using current VLSI technologies, can process a
video stream in real time.
