Architectural paremeters
A list of architectural parameters and their descriptions
| Parameter | Description | Allowable values | Example value |
|---|---|---|---|
| Data type | The numerical format used to perform calculations in hardware | FP16BP8,FP32B16 |
FP16BP8, which means “Fixed point format with width 16 bits and with the binary point at 8 bits” |
| Array size | The size of the systolic array and also the number of scalars in each vector | 2-256 | 8 |
| DRAM0 depth | The number of vectors allocated in DRAM bank 0 | 2^{1-32} | 1048576 (= 2^20) |
| DRAM1 depth | The number of vectors allocated in DRAM bank 1 | 2^{1-32} | 1048576 (= 2^20) |
| Local depth | The number of vectors allocated in on-fabric main memory | 2^{1-16} | 16384 (= 2^14) |
| Accumulator depth | The number of vectors allocated in on-fabric accumulator memory | 2^{1-16} | 4096 (= 2^12) |
| SIMD registers depth | The number of registers to instantiate for each ALU in the SIMD module | 0-16 | 1 |
