#83124 - 8051 vs C - answer is wrong
Responding to: ???'s previous message
Hi, Andy.
In general, my previous message was not only answer; it was a question too, Andy.
Did you red, that I tryed only discuss opinion of my "experienced coleagues"?

If no, i'll repeat: I'm a beginner in embedded sw. I understand, that I'm not a specialist in such a scope. But I know people (among them - Team manager of very succesfull firm), whose opinion is important for me. They've sad, that x51 is rather bad for C-programming. But they (and me too) use THIS architecture for large 'C'-projects, because of cost (tools and hw) and reliability of this one.
As for me, I like C and C++, and I'll never say that asm is better than 'C' for large projects.

About DPTR: tere are some mcu-s with 2 DPTRs (at89s8252 for ex.). Keil sw. have written optimized version of memcpy,memcmp and some others for such a models. Those versions work faster and take less instruction than analogs for 1 DPTR-architecture.
It seems to me, that it's a good example of DPTR influence for code-size and code-speed. And it's a nice example of things, which are good in ASM and bad in 'C' for x51.
