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

 

ItemDescription

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.

This instruction applies to the following shader stages:
