dcl_tgsm_raw (sm5 - asm)

  • Article

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
g#
 [in] A reference to a block of size byteCount of untyped shared memory.
byteCount
 [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.

This instruction applies to the following shader stages:
