#83217 - Not really a '51 task... Responding to: ???'s previous message |
Just think about it: VGA is 640x480 pixels - that's 307200 pixels;
Each pixel requires 3 colour values; even at only 4 bits each that's a total of 450K bytes for the image. That number alone should tell you that this is not a job for an 8051! You might find that there are chips that do all this stuff in hardware, and include an 8051 "core" purely for control functions - but the actual processing isn't really an 8051 job. The 8051 is a small controller - not a data processor! |
