The C29 CPU is very efficient at performing real-time control and DSP operations. Detailed benchmarking demonstrates this capability on the following benchmarks:

• CFFT - Complex Fast Fourier Transform
• FIR - Finite Impulse Response Filter
• IIR_sample - one input sample of an Infinite Impulse Response filter
• IIR_loop - a block of input samples of an Infinite Impulse Response filter
• DCL - Digital Control Library (comprising PI, PID, etc.)
• FCL - Fast Current Loop
• SPLL - Software Phase Locked Loop
• SVGEN - Space Vector Generation
• FOC - Field Oriented Control for Motor Control (same as ACI signal chain)
• Bin_LUT - Binary LUT search

Figure 3-2 shows C29 versus C28 performance on the above benchmarks. On average, considering the benchmarks shown, the C29 is 3x better (in cycles) than the C28 CPU.
