IOS IPS only runs on IOS. You can verify it using the Cisco Feature navigator:

For the new ISR 4000 series, you should start using the new Firepower Threat Defense with the Sourcefire technology - which provides IPS, AMP and URL features.
For just lightweight IPS features, you can use the SNORT IPS features for downloading the signatures from Cisco.
