Shift Registers (SISO, SIPO, PISO, PIPO)
Shift registers are special digital circuits that allow data to be shifted along a single bus or line. They are used to perform various operations such as data processing, memory access, and transmission.
SISO (Shift-In-Shift Out):
In a SISO register, data is shifted in one direction (right to left) during each clock cycle.
A data bus with multiple registers is connected to a single bus with multiple shift registers.
When a new data value is available on the source bus, it is shifted into the destination bus.
The destination bus then shifts out the old data, making space for the new data to be shifted in.
SIPO (Shift-In-Parallel):
In a SIPO register, data is shifted in multiple directions (left to right) during each clock cycle.
A data bus with multiple registers is connected to multiple buses with multiple shift registers.
When a new data value is available on the source bus, it is shifted into the destination bus.
The destination bus then combines the shifted data from all the source buses and outputs the final value.
PISO (Parallel-In-Shift Out):
In a PISO register, data is shifted in multiple directions (left to right and right to left) during each clock cycle.
A data bus with multiple registers is connected to multiple buses with multiple shift registers.
When a new data value is available on the source bus, it is shifted into the destination bus.
The destination bus then combines the shifted data from all the source buses and outputs the final value.
PIPO (Parallel-In-Parallel):
In a PIPO register, data is shifted in multiple directions (left to right and right to left) simultaneously during each clock cycle.
A data bus with multiple registers is connected to multiple buses with multiple shift registers.
When a new data value is available on the source bus, it is shifted into the destination bus.
The destination bus then combines the shifted data from all the source buses and outputs the final value
