This article ( https://wodewangzhishime.blogspot.com/2023/12/sequential-99.html ) mention about how cache and register interact with each others.
This article (https://kamchihau.blogspot.com/2022/08/angle-effect-in-optical-fiber.html) mention about crystal oscillator.
This article (https://wodewangzhishime.blogspot.com/2022/02/httpswodewangzhishime_25.html) mention about tri state buffer.
.
John: What's the usage of a tri state buffer?
Me: It prevent a register from outputing while a register is inputing.
John: Actually, the tri state buffer is useless.
Me: Why?
John: Look at the 1st picture. I inteprete it in code.
.
If (oscillator = Up cycle)
{
current flow from "parallel output line" to register = true.
current flow from "register" to paralleo output line = false.
}
.
Me: When the oscillator is up cycle, the register is low and the parallel output line is high.
John: We don't need a tri state buffer to prevent the register from outputing itself while the oscillator is up cycle.
Me: Correct.
John: Look at the 2nd picture. I inteprete it in code.
.
If (the oscillator = down cyle)
{
the parallel output line for the cache = low.
the cache = high.
The current flow from the cache to the parallel ouput line.
}
