哈哈,大家说得都有理
虽然现在硬件成本下降了,做这东西的确是要花不少钱,而且也没多少实用价值,但外国人的myCPU这个项目的确很优秀,慢慢来,边学边干边玩.没有真实机器的时候可以玩他做的仿真机,
MyCPU搭配的显卡性能还是比较强劲的,性能如下:
Features:
· 6 printed circuit boards with 75 low integrated circuits
· 16 Colors, 640x400 Pixel, 70 Hz mode
· includes a character generator for 8 different character sets
· text modes supported by the Operating System: 80x25, 80x50, 40x25, 40x50
· graphic modes supported by the Operating System: 640x400x2, 160x200x16, 320x200x16,
640x400x16
· the Graphic Unit can be connected to nearly every microcontroller
Limitations:
· Only the 640x400 pixel mode is supported. But all available CRT displays should support
this mode since it is the same mode that nearly every PC uses to display the BIOS or boot
screen.
· There is no support for so called “sprites”. Sprites would make developing games more easy.
The logic for sprites is too heavy to implement (too much parts would be required for a small
feature that is rarely used).
