cisc与risc
http://www.cnblogs.com/createyuan/p/4626235.html
CISC(复杂指令集计算机)和RISC(精简指令集计算机)是当前CPU的两种架构。它们的区别在于不同的CPU设计理念和方法。
RISC的英文全称是Reduced Instruction Set Computer,中文是精简指令集计算机。特点是所有指令的格式都是一致的,所有指令的指令周期也是相同的,并且采用流水线技术。在中高档服务器中采用RISC指令的CPU主要有Compaq(康柏,即新惠普)公司的Alpha、HP公司的PA-RISC、IBM公司的PowerPC、MIPS公司的MIPS和SUN公司的Sparc。
常用的精简指令集微处理器包括DECAlpha、ARC、ARM、AVR、MIPS、PA-RISC、PowerArchitecture(包括PowerPC)和SPARC等。
从计算机诞生以来,人们一直沿用CISC指令集方式。早期的桌面软件是按CISC设计的,并一直沿用。桌面计算机流行的x86体系结构即使用CISC。微处理器(CPU)厂商一直在走CISC的发展道路,包括Intel、AMD,还有其他一些现在已经更名的厂商,如TI(德州仪器)、Cyrix以及VIA(威盛)等。在CISC微处理器中,程序的各条指令是按顺序串行执行的,每条指令中的各个操作也是按顺序串行执行的。顺序执行的优点是控制简单,但计算机各部分的利用率不高,执行速度慢。CISC架构的服务器主要以IA-32架构(IntelArchitecture,英特尔架构)为主,而且多数为中低档服务器所采用。
Intel公司X86为核心的PC系列正是基于CISC体系结构,而 Apple公司的Macintosh则是基于RISC体系结构,CISC与RISC到底有何区别?
从硬件角度来看CISC处理的是不等长指令集,它必须对不等长指令进行分割,因此在执行单一指令的时候需要进行较多的处理工作。而RISC执行的是等长精简指令集,CPU在执行指令的时候速度较快且性能稳定。因此在并行处理方面RISC明显优于CISC,RISC可同时执行多条指令,它可将一条指令分割成若干个进程或线程,交由多个处理器同时执行。由于RISC执行的是精简指令集,所以它的制造工艺简单且成本低廉。
在今年年初的CES2013消费电子展上,酷派春雷MAX 7295首次亮相,5英寸屏幕、四核处理器的配置使它刚一登场便受到了来自各方的强烈关注。在今年的2月,酷派正式发布了酷派春雷MAX 7295,千元级的定价使其拥有超高的性价比,而上市至今超过200万的销量也无疑证明了它的成功,乘着这个契机,酷派和中国联通再次合作,推出了酷派春 雷MAX 7295的后续版本——联通定制版的酷派7295C。作为中国联通联合酷派重点打造的下一款明星机型,酷派对7295C的硬件和系统做出了不同程度的升级 和优化并延续了千元级的价格,使得这款手机的性价比更为突出。

问题1
智能手机与记录仪进行比较,都是嵌入式?
问题2
刷机,装系统,烧机
问题3
手机与记录仪可以装linux吗
问题4 cisc与risc
嵌入式都是risc吗
刷机不成功就用救砖方案吧,要解决也很简单的,那就是采用线刷的方式刷回官方的固件包就可以了
如果手机开不了机,一般先进入recovery里双清一下(恢复出厂设置和清空缓存),如果双清之后还是不行的话,就只能采用线刷的方式来救砖了。
CES2015,手机产业链从上游到终端,巨头们悉数参展:三大巨头芯片公司-高通,Intel,MTK;终端知名品牌公司-苹果,三星,sony,中兴,华 为,联想等都带来了各自的高科技精品。而在手机产业链里,手机方案设计公司通常做为站在品牌公司幕后的英雄一直在助推产业的发展。

很多主板都使用了单芯片设计。已经没有了以前的北桥、南桥概念。
由于市面上主流的CPU基本都集成了内存控制器,所以现在的芯片组(或者叫单芯片)只是提供了简单的IO接口、PCI-E数据通道和硬盘数据通道。比以前精简了。
USB的供电线路,是不经过主板主芯片的。主芯片只提供数据通路。
