Assorted library of utility cores for amaranth HDL.
This library is in active development, therefore beware that things may break!
This library contains:
amlib.io : Basic communication cores:
- UART
- I2C
- I2S (currently transmit only)
- SPI
- MAX7219 SPI LED array driver core
- seven segment driver, value to bitbar driver
- neopixel (WS2812) RGB led strip driver core
amlib.dsp : Building blocks for digital signal processing:
- fixed point FIR filter
- fixed point IIR filter
- fixed point CIC filter
- fixed point halfband filter
- filterbank
- fractional resampler
amlib.soc : Building blocks for SOC creation:
- CPU
- interrupts
- memory
- wishbone
- CSRs
- SimpleSOC
- peripherals
amlib.stream
- LiteX like streams
- stream generators from ROM
- stream to I2C
- stream to/from FIFO
- stream arbiter
- stream to UART
amlib.debug : Internal logic analyzer (ILA)
amlib.test : Convenience tools for automated testing of simulations, CRC
amlib.utils : basic utility modules:
- bit manipulation functions
- one-hot-multiplexer
- synchronizer
- strobe stretcher
- dividing counter
- edge to pulse
- edge detectors
- linear feedback shift register (LFSR)
