Registers - ps_5_0

  • Article

The following input and output registers are implemented in the pixel shader version 5_0.

Input Registers

Register Type Count R/W Dimension Indexable by r# Defaults Requires DCL
32-bit Temp (r#) 4096(r#+x#[n]) R/W 4 No None Yes
32-bit Indexable Temp Array (x#[n]) 4096(r#+x#[n]) R/W 4 Yes None Yes
32-bit Input Attribute (v#) 32 R 4 Yes None Yes
Element in an input resource (t#) 128 R 1 No None Yes
Sampler (s#) 16 R 1 No None Yes
ConstantBuffer reference (cb#[index]) 15 R 4 Yes(contents) None Yes
Immediate ConstantBuffer reference (icb[index]) 1 R 4 Yes(contents) None Yes

 

Output Registers
