Chapter 3 is devoted to the analysis of the kernel structure of DSP56F807, and the introduction of the instruction system and the interruptmechanism.
第三章对DSP56F807的内核结构进行了分析,并介绍其指令系统和中断机制。

Tasklets are scheduled through the softirq mechanism, sometimes through ksoftirqd (a per-CPU kernel thread), when the machine is under heavy soft-interrupt load.
通过软中断机制来调度微线程,当机器处于严重软件中断负荷之下时, 可通过 ksoftirqd(一种每 CPU 内核线程)软中断来调度。

The hardware context switch mechanism was adopted by MPC8250. It makes interrupt responding time of MPC8250 has less relativity with operation system.
