The instr_addr register is used to indicate the DDR memory
address of instructions for the DPU for the RNN kernel. The default width of the DDR
memory address is 64-bit, so two 32-bit registers are used to represent the
instruction address. The details of the instr_addr register are shown in the
following table.
| Bit | Register | Address | R/W | Description |
|---|---|---|---|---|
| 31:0 | INSTR_ADDR_H | 0x1C | R/W | The higher 32 bits of instructions address in DDR. It is shared with model parameter address register. |
| 31:0 | INSTR_ADDR_L | 0x20 | R/W | The lower 32 bits of instructions address in DDR. |
