加、减、乘法指令对标志位cf、of的设置探讨

8086CPU的指令在执行过程中,会对标志位产生影响。而相同的标志位在不同的指令的设置规则及表示的意义是不同的。特别是在算术运算指令ADD、SUB、MUL中都有对cf、of标志的设置,在加法、减法指令中这两个标志都是表示溢出,而在乘法指令中这两个标志不再表示溢出了。本文就探讨这些差别。     

Reconfigurable Communication Processor： A New Approach for Network Processor

As the traditional RISC ASIC/ASSP approach for network processor design can not meet the today‘s requirements, this paper described an alternate approach, Reconfigurable Processing Architecture, to boost the performance to ASIC level while reserve the programmability of the traditional RISC based system. This paper covers both the hardware architecture and the software development environment architecture.
