Digital Function Generators TRIZ Cases
- ARCPI Boosting Time Control With Saturable Inductor Compensation
A lookup-table and resonance-based boosting time corrects saturable inductor nonlinearity to maintain zero-voltage switching in PWM ARCPIs.
- Lookup Table Signal Mapping for Lower Interpolation Error
A pre-function reshapes the input grid before LUT interpolation, cutting non-linear mapping errors without sacrificing processing speed.
- Recursive Digital Sinusoid Correction for Quantization Drift
Periodic high-precision replacement values correct recursive quantization drift, preserving sinusoid accuracy without large on-chip RAM.
- Displacement Sensor Excitation with Intermediate Buffer Control
An intermediate control module stores excitation lookup tables and drives the DAC independently, easing DMA load and freeing SPI resources.
- Image Sensor Data Arrays for High-Throughput Focus Detection
Pixel-position-ordered optical data and precomputed coefficients reduce memory transactions for faster focus detection and image processing.
- Interval Computing Subdomain Sampling Optimization
Subdomain sampling selects optimal box sizes to eliminate exhaustive searches on empty subdomains.
- Hardware Acceleration Circuit for Neural Network Non-Linear Functions
A hardware acceleration circuit processes exponential function values to obtain specific non-linear function results.
- Arbitrary Waveform Sequencer with Dynamic Dead Time Control
A waveform sequencer manages file transitions using dedicated control units for precise timing and increment conditions.
- Sine/Cosine Generator Angle Decomposition for High Precision
Decomposing input angles into coarse and fine components reduces hardware resources while achieving greater than 18 bits of precision.
- Phase-to-Amplitude Converter for DDS Using Segmented Logic
Segmenting phase inputs into upper and lower bits reduces ROM size and logic complexity while maintaining high SFDR in direct digital synthesizers.
