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)
• NRZI encoder
• shift register
