早在2000年之前,国内就有不少音频发烧友寻思着如何利用淘汰下来的电脑配件设计专用的数字音频播放器,话题围绕着AMD K5、Intel奔腾、Cyrix的586等处理器进行讨论。在当时,种种问题困扰着这些发烧友们,如何不用风扇达到静音?如何盲操作播放曲子?如何将机器设计得又小又好看?如何充分降低成本?这些都是当年的拦路石,但这些思想上的火花,却丝毫不比国外的发烧友来得晚,甚至更早。光有火花还不行,还得有充足的物质条件。前些时候,我们看到新闻说:“我国中科院计算所自主研发的CPU龙芯芯片组装的电脑今年6月将小批量生产,价格将在1500元左右。同时由于龙芯产业进程的不断推进,我国国产的千元龙芯电脑有望普及。”我们认为这无疑是一大契机,而这篇文章就是要围绕如何利用龙芯Ⅱ芯片来设计数字播放器。而且,随着数字媒体的飞速发展,我们已经不满足于纯粹的数字音频播放器了,而是需要一套全能的数字媒体播放器。
As early as 2000, there are many domestic audio enthusiasts wondering how to use out of the computer accessories designed dedicated digital audio player, the topic revolves AMD K5, Intel Pentium, Cyrix 586 and other processors for discussion. At the time, various problems plagued these enthusiasts, how to mute without a fan, how to play music blindly, how to design a small and attractive machine, and how to reduce costs to a great extent. All of these are the stone of the past, but these ideas Of the spark, but no later than foreign enthusiasts came late, or even earlier. There is no spark of light, but also have sufficient material conditions. Some time ago, we saw the news saying: “The computers assembled by the Chinese Academy of Sciences Institute independently developed CPU Loongson chipsets will be manufactured in small quantities in June this year, at a price of about 1,500 yuan. Due to the continuous advancement of Godson’s industrial processes, The domestic 1000-yuan Loongson computer is expected to popularize. ”" We think this is undoubtedly a great opportunity, and this article is about how to use the Loongson II chip to design a digital player. Moreover, with the rapid development of digital media, we are not satisfied with the pure digital audio player. Instead, we need an all-in-one digital media player.
