ARMadillo
1.0.0
Raspberry Pi Zero的最小手臂OS。
这是我个人的个人奖金项目,用于“嵌入式系统设计” [ECE1258]。
目前,它:
启动操作系统并初始化所有内容后,执行将传递给可以通过 /dev /ttyusb0访问的演示控制台。
演示控制台接受几个命令:
help
Displays a list of available commands
intr
Setups a repeatable IRQ interrupt that blinks the LED light of
the Pi once every second.
proc
Setups the scheduler, launches a kernel and a user process and
switches between them seamlessly.
lock
Same as proc, but also utilizes mutex locks.
Control is still switched continuously between the two processes;
however, they share a lock, and they sequentially un/lock it.
fpuo
Performs a floating point operation using the floating point coprocessor.
Proof can be found in the kernel.list file that is produced during
compilation if one looks for the fpu_mult details.
Note that separate function must be used to produce the result
(fpu_mult in common/stdlib.c), otherwise the compiler just
precalculates the result.
