自动控制杂志
自动控制杂志I decided on a PIC 16C620. It was small with 18 pins,
and had a useful amount of memory. Most importantly, I
could get a bunch of them cheap! Since the game is simple,
very few I/O pins were

JPEG压缩matlab源码
JPEG压缩解压缩的matlab源代码：
1) take an image (2D matrix) and devide it to 8x8 matrices
2) for each matrix (8x8) use the DCT conversion (from the signal
processing toolbox). you will get an (8x8) mat
