Largest sibling of the Trinity TTSKY26b triad. 32 tiles (8x4) neuromorphic accelerator with 8 cortical columns, 20-PE GF16 mesh, 24 SUPER-CROWN modules, 6 PhD-anchored monitors, and a 4-port die-to-die holographic mesh router.
The design integrates several blocks around the canonical Trinity anchor:
GF16 format: 1 sign + 6 exponent (bias=31) + 9 mantissa. All mantissa multiplies use shift-and-add (zero new standalone star operators in synthesisable RTL).
On reset the chip drives the canonical Trinity anchor 0x47C0 onto the output pins. This is the same constant emitted by the Phi (1x1) and Euler (8x2) siblings.
After reset (ui_in = 0x00):
Combined: 0x47C0 = GF16(30.0) = dot4(1, 2, 3, 4) (1, 2, 3, 4).
To select packet path mode, drive ui_in[0] high. To probe the Lucas ROM, drive lucas_idx[2:0] on ui_in[3:1].
No external hardware required. The die-to-die mesh pins (uio_out[3:0] TX and uio_in[7:4] RX) are directly observable; in a single-die test they can be left unconnected.
| # | Input | Output | Bidirectional |
|---|---|---|---|
| 0 | load_mode (0=canonical 0x47C0 default, 1=packet path + status_byte) | result[0] (canonical 0x47C0 default; mesh result_lo[0] after FSM) | D2D n_tx — North TX (output): spike_count[3] activity bit |
| 1 | lucas_idx[0] | result[1] | D2D e_tx — East TX (output): spike_count[0] activity bit |
| 2 | lucas_idx[1] | result[2] | D2D s_tx — South TX (output): GF16 route tag bit |
| 3 | lucas_idx[2] | result[3] | D2D w_tx — West TX SYNC strobe (output, LAYER-FROZEN gated per PhD Thm 36.1 R18) |
| 4 | tri_status_msb (ui[4:2]=3b111 → token balance on uo/uio_out) | result[4] | D2D n_rx — North RX (input from peer die) |
| 5 | unused (ui[4:2] tri_status decoded, ui[7:5] unused) | result[5] | D2D e_rx — East RX (input from peer die) |
| 6 | crown_addr[6:0] MSB (with ui[5:0]) | result[6] | D2D s_rx — South RX (input from peer die) |
| 7 | unused | result[7] | D2D w_rx (input from peer die) / crown_mode enable when high + load_mode=0 |
