CodeXL User GuideUsing this view, you can inspect the ISA code of GCN devices and see the estimation for instruction cost in clock cycle. The view contains 5 columns:
- Address: the instruction’s offset within the program (in bytes)
- Opcode: the operation to be performed
- Operands: the data for the operation
- Cycles: the number of clock cycles which are required by a Compute Unit in order to process the instruction for a 64-thread Wavefront, while neglecting the system load and any other runtime-related factor.
- Instruction Type: the category of instructions to which the instruction belongs
- Hex: binary representation of the instruction, in hexadecimal format
Notes:
1. Note that code labels which appear in the Operands column are clickable. By clicking on a label link, you can navigate to the label’s spot in the code.
2. Note that this view is only available for GCN devices. For pre-GCN devices, the plain textual ISA view will be displayed.
