Operations using 16 bits for 8 bits variables

Fellows, in the code below: unsigned char test1, test2, test3, dummy; if (test1 != (test2 + 1)) dummy = 0; if (test1 != (unsigned char)(test2 + 1)) dummy = 0; if (test1 != (test2 + test3...

assembler prefix for 16 and 32 bit operations

So I'm doing some very sophisticated code in assembler on my fav little processor. I recently discovered that most processors have special prefix codes so they can carry out wider operations. like the...

Bit Operator

Hi , A "bit" of a fundamental query. Suppose I declare two bit variables bit MyBit1,MyBit2; I need to do something if both bits are 1. Are these two methods equivalent: if(MyBit1...
