I have an array of 100 uint8_t's, which is to be treated as a stream of 800 bits, and dealt with 7 bits at a time. So in other words, if the first element of the 8-bit array holds 0b11001100 and th...

I'm trying to convert my library from various formats into HEVC 8-bit mainly to shrink my library down. This is generally working but I've run into an issue when trying to convert an existing file ...

A long time ago I had an apple ][ . I remember the command call – 151 But I can not remember what it did ?

I was wondering what is the best way to convert a 24-bit RGB color (8 bits per color) into an 8-bit color (2bits Blue, 3 Green, 3 Red). I'd like C code for doing this.

I'm implementing global illumination in my game engine with "reflective shadow maps". RSM has i.a. color texture. To save memory. I'm packing 24 bit value into 8 bit value. Ok. I know how to pack i...

"Faster than avr200b.asm"? The mpy8u-routine from avr200b.asm for those processors of Atmel's AVR family that do not implement any of the MUL instructions seems pretty generic, but mpy16u loo...

I know this has been asked before, but I have not been able to reach a solution. I apologize if the topic is duplicated, but I think it's not. I have a number extracted from a Uint16Array to conve...

I was reading a tutorial about creating a Game Boy emulator, I understand that the Game Boy uses an 8-bit CPU, but I can't understand why the Gameboy uses two types of data: bytes (8 bits) and word...

I know this can be accomplished in different ways, and there are already some example implementations suggested in other answers. So what I'm asking is what is the most efficient in terms o...

Something that has always confused me is how 8-bit computers access more than 256 bytes of RAM. I know that it must use two registers, but can any one show me an example of what this would look lik...

Trying things out as I learn C code, I wanted to test something. It worked as expected, but throws the warning Warning 1 assignment from incompatible pointer type [enabled by default] The cod...

This question may be redundant, but I didn't found exact answer. What is the Difference between C 8 bit 16-bit 32-bit compilers. how the .exe differ generated by different compilers for sam...

I was looking at the ImageConverter class, trying to figure out how to convert a BufferedImage to 8-bit color, but I have no idea how I would do this. I was also searching around the internet and I...

I have used and like the Atmel ATMEGA and ATTINY series microcontrollers, and think them quite good. One thing I am not terribly fond of though is the fact that they (and Microchip PIC uC family al...

I'm afraid I have a question on a detail of a rather oversaturated topic, I searched aroudn a lot, but couldn't find a clear answer to that specific obvious -imho- important, problem: When conver...

Is it possible to add two signed 8-bit numbers together and set both the carry and overflow bits?
