Are there libraries available for this part that support FFT’s and digital filters? What math libraries are included with the tools set (Keil and IAR)?
Basically ABuda is right, you can use the CMSIS DSP-Lib with any C-Compiler.
Normally it is available with Keil MDK and IAR EWARM (also with evaluation copies), but also with GNU compiler tool-chains already. CMSIS is originally for ARM Cortex cores, but it is no problem to use individual functions with ARM7-TDMI cores, because the lib is available as source code.
The functions are usually available within the tool-chain folder under ...arm/CIMSIS/DSP_Lib.
Documentation for it can be found online @

But anyway, there are other resources easy to find via Google.
This forum is for the Analog Devices device functions. I know there are some math functions that come with the cortex parts as part of a CMSIS package, but I'm not sure what keil or IAR provide for the ARM7 parts. Best bet is contact them directly. I would say that any generic math functions implemented for ARM7 would work on the ADuC7061
