sim 文件系統(tǒng)In addition, its quality of service reduces because of reliance on traditional circuit-switched network elements. At that former time, people hoped to build a based system, which could access a centralized server network, would always have access to the latest traffic information and could provide web links. What this trend is a momentous request for mobile services based on high-SPEED packet data transfer. Hence, a new standard, GPRS, came into being in order to fill people’s bill.

VHDL是由美國國防部為描述電子電路所開發(fā)的一種語言，其全稱為(Very High Speed Integrated Circuit) Hardware Description Language。 與另外一門硬件描述語言Verilog HDL相比，VHDL更善于描述高層的一些設(shè)計(jì)，包括系統(tǒng)級(jí)（算法、數(shù)據(jù)通路、控制）和行為級(jí)（寄存器傳輸級(jí)），而且VHDL具有設(shè)計(jì)重用、大型設(shè)計(jì)能力、可讀性強(qiáng)、易于編譯等優(yōu)點(diǎn)逐漸受到硬件設(shè)計(jì)者的青睞。但是，VHDL是一門語法相當(dāng)嚴(yán)格的語言，易學(xué)性差，特別是對(duì)于剛開始接觸VHDL的設(shè)計(jì)者而言，經(jīng)常會(huì)因某些小細(xì)節(jié)處理不當(dāng)導(dǎo)致綜合無法通過。為此本文就其中一些比較典型的問題展開探討，希望對(duì)初學(xué)者有所幫助，提高學(xué)習(xí)進(jìn)度。
