The ability to write efficient, high-Speed arithmetic routines ultimately depends upon your knowledge of the elements of arithmetic as they exist on a computer. That conclusion and this book are the result of a long and frustrating search for information on writing arithmetic routines for real-time embedded systems. With instruction cycle times coming down and clock rates going up, it would seem that speed is not a problem in writing fast routines. In addition, math coprocessors are becoming more popular and less expensive than ever before and are readily available. These factors make arithmetic easier and faster to use and implement. However, for many of you the systems that you are working on do not include the latest chips or the faster processors. Some of the most widely used microcontrollers used today are not Digital Signal Processors (DSP), but simple eight-bit controllers such as the Intel 8051 or 8048 microprocessors.

VHDL是Very High Speed Integrated Circuit Hardware Description Language的縮寫, 意思是超高速集成電路硬件描述語言。對于復(fù)雜的數(shù)字系統(tǒng)的設(shè)計(jì),它有獨(dú)特的作用。它的硬件描述能力強(qiáng),能輕易的描述出硬件的結(jié)構(gòu)和功能。這種語言的應(yīng)用至少意味著兩種重大的改變:電路的設(shè)計(jì)竟然可以通過文字描述的方式完成;電子電路可以當(dāng)作文件一樣來存儲。隨著現(xiàn)代技術(shù)的發(fā)展,這種語言的效益與作用日益明顯,每年均能夠以超過30%的速度快速成長。 這次畢業(yè)設(shè)計(jì)的內(nèi)容是在簡要介紹了VHDL語言的一些基本語法和概念后,進(jìn)一步應(yīng)用VHDL,在MAX+plusII 的環(huán)境下設(shè)計(jì)一個(gè)電子鐘,最后通過仿真出時(shí)序圖實(shí)現(xiàn)預(yù)定功能。電子鐘的時(shí)間顯示用到了七段數(shù)碼管(或稱七段顯示器)的電路設(shè)計(jì),內(nèi)部的時(shí)間控制輸出則用到了各種設(shè)計(jì),包括:加法計(jì)數(shù)器,掃描電路,控制秒、分、時(shí)的分頻電路,各種數(shù)制的轉(zhuǎn)換。
