computer architecture

Let’s hack the fx-991es calculator. Precisely we are exploiting the Buffer Overflow technique and doing some stuff {TODO}.Let me be clear that the calculator is a computer anyways. Buckle up as weare going to dive deep into some Computer Architecture. Basics of fx-991es Don’t get afraid of fancy words or fancy figures. After all they are the simple chain of concepts hidden behind some characters. Chip: nX-u8 Series chip. Manual Here Architecture: Super Harvard CPU Resources and Programming Model : In Gajju We Trust General Architecture Most modern computer architecture follow the Vonn Neumann Architecture....

Migrated from logicaletter.com computers are intricate to understand at the superficial level, but at its core all you will see are logic. Logic makes everything. The invention of transistors allowed us to create logic gates and those logic gates allow computers to add. couple of XOR gates and AND gates can create a full adder. but how do computers subtract? they use something called 1’s complement because computer developers thought “screw this , we are not going to build another circuit for subtraction, rather we will use same circuit board that we use for addition”....
