Eight 32-bit identical processors:

• Access to all I/O pins, plus four fast DAC output channels and four fast ADC input channels
• 512 longs of dual-port register RAM for code and fast variables
• 512 longs of dual-port lookup RAM for code, streamer lookup, and variables
• Ability to execute code directly from register RAM, lookup RAM, and hub RAM
• ~358 unique instructions for math, logic, timing, and control operations
• 2-clock execution for all math and logic instructions, including 16 x 16 multiply
• 6-clock custom-bytecode executor for interpreted languages
• Ability to stream hub RAM and/or lookup RAM to DACs and pins or HDMI modulator
• Ability to stream pins and/or ADCs to hub RAM
• Live colorspace conversion using a 3 x 3 matrix with 8-bit signed/unsigned coefficients
• Pixel blending instructions for 8:8:8:8 data
• 16 unique event trackers that can be polled and waited upon
• 3 prioritized interrupts that trigger on selectable events
• Hidden debug interrupt for single-stepping, breakpoint, and polling

Central hub serving the processors:

• 512 KB of contiguous RAM in a 20-bit address space
• 32-bits-per-clock sequential read/write for all cogs, simultaneously
• readable and writable as bytes, words, or longs in little-endian format
• last 16KB of RAM write-protectable

32-bit, pipelined CORDIC solver with scale-factor correction

• 32-bit x 32-bit unsigned multiply with 64-bit result
• 64-bit / 32-bit unsigned divide with 32-bit quotient and 32-bit remainder
• 64-bit → 32-bit square root
• Rotate (X32,Y32) by Theta32 → (X32,Y32)
• (Rho32,Theta32) → (X32,Y32) polar-to-cartesian
• (X32,Y32) → (Rho32,Theta32) cartesian-to-polar
• 32 → 5.27 unsigned-to-logarithm
• 5.27 → 32 logarithm-to-unsigned
• Cogs can start CORDIC operations every 8 clocks and get results 55 clocks later
• 16 semaphore bits with atomic read-modify-write operations
• 64-bit free-running counter which increments every clock, cleared on reset
• High-quality pseudo-random number generator (Xoroshiro128**), true-random seeded at start-up, updates every clock, provides unique data to each cog and pin
• Mechanisms for starting, polling, and stopping cogs
• 16 KB boot ROM
• Loads into last 16 KB of hub RAM on boot-up
• SPI loader for automatic startup from 8-pin flash or SD card
• Serial loader for startup from host
• Hex and Base64 download protocols
• Terminal monitor invocable via “> ” (greater than followed by a space) and then CTRL+D
• TAQOZ Forth invocable via “> ” (greater than followed by a space) and then ESC

64 Smart I/O pins:

• 64 identical Smart I/O pins, externally powered in blocks of 4
• 8-bit, 120-ohm (3 ns) and 1 k-ohm DACs with 16-bit oversampling, noise, and high/low digital modes
• Delta-sigma ADC with 5 ranges, 2 sources, and VIO/GIO calibration
• Several ADC sampling modes: automatic 2n SINC2, adjustable SINC2/SINC3, oscilloscope
• Logic, Schmitt, pin-to-pin-comparator, and 8-bit-level-comparator input modes
• 2/3/5/8-bit-unanimous input filtering with selectable sample rate
• Incorporation of inputs from relative pins, -3 to +3
• Negative or positive local feedback, with or without clocking
• Separate drive modes for high and low output: logic / 1.5 k / 15 k / 150 k / 1 mA / 100 µA / 10 µA / flat
• Programmable 32-bit clock output, transition output, NCO/duty output
• Triangle/sawtooth/SMPS PWM output, 16-bit frame with 16-bit prescaler
• Quadrature decoding with 32-bit counter, both position and velocity modes
• 16 different 32-bit measurements involving one or two signals
• USB full-speed and low-speed (via odd/even pin pairs)
• Synchronous serial transmit and receive, 1 to 32 bits, up to clock/2 baud rate
• Asynchronous serial transmit and receive, 1 to 32 bits, up to clock/3 baud rate

Clock Modes:

• Six different clock modes, all under software control with glitch-free switching between sources
• Internal 20 MHz+ RC oscillator, nominally 25 MHz, used as initial clock source
• Crystal oscillator with internal loading caps for 7.5 pF/15 pF crystals, can feed PLL
• Clock input, can feed PLL
• Fractional PLL with 1..64 crystal divider → 1..1024 VCO multiplier → optional (1..15)*2 VCO post-divider
• Internal ~20 kHz RC oscillator for low-power operation (130 µA)
• Clock can be stopped for lowest power until reset (100 µA, due to leakage)

Power requirements:

• Power core via VDD pins @ 1.8 VDC
• Power I/O pins in groups of 4 via VIO pins @ 3.3 VDC
