Signal Processing Controller
PCI Data Acquisition and Signal Processing Controller is Windows' generic label for chips in the signal processing class. On Intel PCs it is often a thermal part, fixed by the Dynamic Tuning Technology or Dynamic Platform and Thermal Framework driver from your PC maker. Check the hardware ID to be sure.

Match the first line of Hardware Ids in Device Manager (Properties, Details) against this list. Names come from the public PCI ID Repository.
The short version
What to install and where it comes from. Every link goes to the manufacturer or Microsoft, never to a copy.
Official files only, nothing bundled
Step by step
Open the entry's Details tab
In Device Manager, right-click the entry, choose Properties, Details, then Hardware Ids. Copy the line that starts with PCI.
Match the ID
Compare the VEN and DEV codes with the table. Names containing Thermal, Dynamic Tuning or Dynamic Platform and Thermal Framework confirm the cause.
Check Windows Update
Open Settings, Windows Update, Advanced options, Optional updates. Intel says the driver can arrive through Windows Update on supported systems.
Download from the PC maker
Find your exact model on the maker's support page. Look for Intel Dynamic Platform and Thermal Framework, Intel Dynamic Tuning, or a bundled chipset or platform package.
Fall back to Intel's chipset utility
If the maker offers nothing, run the Chipset INF Utility, which names many chipset parts, then rescan in Device Manager.
A label from a class code
Every PCI chip reports a class code. Class 11 means signal processing controller, and Windows turns the sub-type into the long name you see here. When no INF file matches the chip, the long name stays and the yellow mark appears. The name tells you the family of chip, not what it does in your PC.
Why Intel PCs show it so often
Intel places its thermal and power tuning hooks in PCI space. The older Dynamic Platform and Thermal Framework, shortened to DPTF, and the newer Dynamic Tuning Technology both appear this way. The hardware ID table lists examples from the public PCI list, including processor, chipset and Raptor Lake participants. These pieces let the PC maker’s tuning policy talk to the processor, so the maker is the right source for the driver.
Intel is clear on this point. Its support article says the driver is meant to be integrated by system makers and should be taken from them. It names three routes: the maker’s support site, Windows Update on supported systems, and the Intel Platform Performance Package through the Intel Download Center. Ordinary users generally cannot switch the feature on themselves unless the maker enabled it.
When it is not Intel
A VEN code other than 8086 means a different chip. Search that code and device number in the PCI ID Repository to learn the maker, then look on your PC maker’s site under Sensors, Platform or Chipset. We could not confirm one driver for every non-Intel case, so use the ID rather than guessing.
Questions
Is this a graphics or camera problem?
Not usually. The name only reflects the class code. On Intel PCs it often turns out to be power and thermal management, while on other machines it can be a sensor or capture device.
Will skipping the driver overheat my PC?
Fans and CPU protection still work without it. The driver lets the PC maker's thermal profile run, so a laptop can run hotter, louder or with shorter battery life without it.
Can I install any version from Intel?
Intel says to use the driver from your system or motherboard maker, because maker versions can include platform changes even when the numbers match.
Should I uninstall it if it misbehaves?
Intel advises against removing or downgrading it. Update it from the maker instead.
