问题 I am brand new to learning MIPS assembly code, and we got our first coding assignment. I am getting an error when I run my program (which is supposed to be a tester for another function we have to write) saying "spim: (parser) Label is defined for the second time on line 13 of file /home/jlr247/215_A2_work/jlr247-a2-A.s main: ^" The code I have is: .data .align 4 _arrA: .space 400 _arrB: .space 400 .text main: la $t0, _arrA #load base address of array A la $t1, _arrB #load base address of

Handling non-digit user input to a MARS read-integer system call?

阅读更多关于 Handling non-digit user input to a MARS read-integer system call?

问题 I'm doing a simple program of car park that takes the input from the user, and branch to a label in accordance of the input. The problem is, the program always ends abruptly if the user enter an input with different data type than integer (like "a" or any alphabets) Below is my code (that relevant to the input part) : li $v0,5 #system call to get input from user syscall li $t1,2 beq $v0,1,park # go to "park" section of codes if input is 1 beq $v0,2,exit # go to "exit" section of codes if

"整理一些除了Google Adsense以外比较适合英文站的国外广告联盟"：关键词：整理一些除了 google adsense 以外比较适合英文站国外广告联盟最近一直在研究除了google adsense 以外的其他适合英文站的国外广告联盟，以替代被google adsense k站中的广告，不然不错的流量就太可惜了，在网上搜索，整理出如下几个口碑不错的广告联盟。如果你有其他更好的广告联盟，欢迎大家留言补充啊！ infolinks- 一个内文广告联盟，效果很好，除adsense外必做的广告，因为它并不影响adsense的广告位，相当于多一份收入。支持paypal付款。 adbrite – 跟adsense类似的关键字广告，不过广告形式比google多，如整页弹窗和内文广告等，如果你的adsense不幸挂了，这是第一选择，最初开始放的时候单价会低，半个月至一个月以后单价会慢慢变高，而且整页弹窗的效果也非常不错。一般英文站的效果要好，中文站基本没有效果。 kontera – 内文广告联盟，和infolinks一样，效果一般，收入有时不稳定，但是如果能争取到他们的cpm计划（有流量和质量要求），效果会很不错。支持paypal付款，申请加入有最低流量要求，有一定流量的网站一般还是能通过得。 chitika – 已经由原来的cps转向cpc

QtSPIM: Explanation for code shown without loading program

阅读更多关于 QtSPIM: Explanation for code shown without loading program

问题 The QtSPIM MIPS assembler already shows some lines of code even though there is no program loaded, like can be seen on https://ecs-network.serv.pacific.edu/ecpe-170/tutorials/qtspim-tutorial. I assume this is required for loading programs, but I would be very interested in an exact explanation to understand all details. 回答1: A QtSPIM program consists of two parts: an exception handler, and a user program. The default exception handler includes both a short user-mode startup code sequence
