The hardware design of stb is discussed and the pcb ( printed circuit board ) picture is presented 完成了數(shù)字電視機(jī)頂盒的硬件設(shè)計(jì)與pcb制板。
The thesis includes the design of hard circuit , pcb ( printed circuit board ) , driver and application soft 本課題包括硬件電路、印刷電路板( pcb ) 、驅(qū)動(dòng)程序和應(yīng)用軟件的設(shè)計(jì)。
The pld ( programmable logic device ) is chosen as the core of the pcb ( printed circuit board ) , which is designed to implement the function of dongle 在設(shè)計(jì)中,選擇altera公司的pld器件做為核心芯片來實(shí)現(xiàn)加密鎖,完成對(duì)軟件的保護(hù)。
With the development of semiconductor process technology , nowadays a system on a pcb ( printed circuit board ) which is composed of several ics can be integrated into a chip 隨著集成電路制造工藝的飛速發(fā)展,人們已經(jīng)可以將原先用各種電路搭建的板極系統(tǒng)集成在一塊芯片上。
With the development of semiconductor process technology a system on a pcb ( printed circuit board ) which is composed of several ics can be integrated into a chip 隨著集成電路工藝的飛速發(fā)展,人們已經(jīng)可以將原先的板級(jí)系統(tǒng)集成在一塊芯片上,系統(tǒng)芯片逐漸成為集成電路設(shè)計(jì)的主流發(fā)展趨勢(shì)。
