New DSP Extensions to the Embench Benchmark Suite
summary
Adds three concrete benchmarks to Embench: FIR, IIR, FFT (Radix‑2) implemented in portable C with tunable parameters (taps, block size, fixed or floating point) and a state structure so runs reflect real streaming use. Benchmarks avoid architecture‑specific tuning, report a single Embench score plus per‑benchmark details and code size, live on GitHub, and reference ARM CMSIS DSP for workload shape. Early use validates them for compiler and vector‑ISA experiments and for architecture scalability studies.
