Pika 10k 16x «FULL ✰»
This cable is overkill for casual nightstand charging. It is designed for power users:
The ISA extends a base RISC-V RV32IM with custom vector extensions (Zvk16x). Example instructions: pika 10k 16x
| Mnemonic | Description | Latency |
|----------|-------------|---------|
| vadd16 vd, vs1, vs2 | 16x 16-bit vector add | 1 cycle |
| vmacc16 vd, vs1, vs2 | 16x 16-bit multiply-accumulate | 2 cycles (pipelined) |
| vld16 vd, (rs1) | Load 16 words (10K space) into vector reg | 1 cycle (if bank-aligned) |
| vperm16 vd, vs1, vm | Permute across 16 lanes | 3 cycles | This cable is overkill for casual nightstand charging
Note on "10K" addressing: The memory space is flat, 14-bit addressable (2^14 = 16,384), but only the lower 10,240 locations are implemented. Access above 0x2800 causes a trap. Access above 0x2800 causes a trap
Rendering high-fidelity video is computationally expensive. A "16x speed" improvement would mean turning a 30-minute rendering process into roughly 2 minutes. This moves AI video from a "set it and forget it" overnight task to a real-time creative tool, allowing for instant iteration during a brainstorming session.
| Issue | Description | Workaround | |-------|-------------|-------------| | Erratum #1 | Simultaneous load and store to same bank in different lanes causes data corruption | Use software bank arbitration or separate load/store phases | | Erratum #2 | 10K memory does not support byte-write; only 16-bit aligned writes | Pad data to 16-bit boundaries | | Limitation #1 | No hardware divide/square root in 16x SIMD | Implement in software or use scalar unit | | Limitation #2 | Maximum 10,240 instructions in tightly coupled memory (TCM) for fetch | Larger loops must spill to slower external flash |
