Today I'll attempt to look at the channel switch microcode. Its only tasks should be loading/storing the context data and some administrative stuff.
Let's continue REing the branch instructions.
Today my goal is to look into an issue I've briefly mentioned at the beginning, but ignored afterwards: the code fetch and execution process.
Today's aim is to RE the remaining $a-related opcodes. That is, boring but required stuff before we can get to looking at the microcode.
No obvious place to go now. Let's try some statistical analysis. We'll count how many times each opcode [as distinguished by top 8 bits] is used.
