dcl_tgsm_raw (sm5 - asm)
Declare a reference to a region of shared memory space available to the compute shader’s thread group.
| dcl_tgsm_raw g#, byteCount |
|---|
| Item | Description |
|---|---|
|
[in] A reference to a block of size byteCount of untyped shared memory. | |
|
[in] Must be a multiple of 4. |
Remarks
The total storage for all g# must be <= the amount of shared memory available per thread group, which is 32kB.
In an extreme case, you can declare 8192 total g#’s, each with a byteCount of 4.
In the opposite extreme, you can declare a single g# with a byteCount of 32768.
Note cs_4_0 and cs_4_1 supports dcl_tgsm_structured, but not dcl_tgsm_raw.
