dcl_tgsm_structured (sm5 - asm)
Declare a reference to a region of shared memory space available to the compute shader s thread group. The memory is viewed as an array of structures.
| dcl_tgsm_structured g#, structByteStride, structCount |
|---|
| Item | Description |
|---|---|
| g# |
[in] A reference to a block of shared memory of size structByteStride * structCount bytes. |
| structByteStride |
[in] The structure stride. This value is a uint in bytes and must be a multiple of 4. |
| structCount |
[in] The number of structures. |
Remarks
The total storage for all g# must be <= the amount of shared memory available per thread group, which is 32kB, or 8192 32-bit scalars.
In an extreme case, you can declare 8192 total g# s, if each has a structByteStride of 4 and a structCount of 1.
In the opposite extreme, you can declare a single g# with a structure stride of 32kB and a structure count of 1.
