v16 v17 1489 1489 SSAMP sampler. The instruction performs Z-compare operation choosen in SSAMP sampler. 1490 1490 The first address register holds the Z-compare value.</p> 1491 <h4>IMAGE_SAMPLE_C_B</h4> 1492 <p>Opcode: 45 (0x2d)<br /> 1493 Syntax: IMAGE_SAMPLE_C_B VDATA(1:4), VADDR(3:6), SRSRC(4,8), SSAMP(4)<br /> 1494 Description: Get sampled pixel value from SRSRC image at address VADDR by using 1495 SSAMP sampler. The instruction performs Z-compare operation choosen in SSAMP sampler. 1496 The first address register holds the Z-compare value. 1497 Next address register holds the LOD bias value.</p> 1498 <h4>IMAGE_SAMPLE_C_B_CL</h4> 1499 <p>Opcode: 46 (0x2e)<br /> 1500 Syntax: IMAGE_SAMPLE_C_B_CL VDATA(1:4), VADDR(4:7), SRSRC(4,8), SSAMP(4)<br /> 1501 Description: Get sampled pixel value from SRSRC image at address VADDR by using 1502 SSAMP sampler. The instruction performs Z-compare operation choosen in SSAMP sampler. 1503 The first address register holds the Z-compare value. Next address register holds the 1504 LOD bias value. The last address register holds the clamp value.</p> 1491 1505 <h4>IMAGE_SAMPLE_C_CL</h4> 1492 1506 <p>Opcode: 41 (0x29)<br /> … … 1517 1531 The first address register holds the Z-compare value. The last address register holds 1518 1532 the LOD value.</p> 1533 <h4>IMAGE_SAMPLE_C_LZ</h4> 1534 <p>Opcode: 47 (0x2f)<br /> 1535 Syntax: IMAGE_SAMPLE_C_LZ VDATA(1:4), VADDR(2:5), SRSRC(4,8), SSAMP(4)<br /> 1536 Description: Get sampled pixel value from SRSRC image at address VADDR by using 1537 SSAMP sampler. The instruction performs Z-compare operation choosen in SSAMP sampler. 1538 The first address register holds the Z-compare value. Force use of mipmap level 0 (???).</p> 1519 1539 <h4>IMAGE_SAMPLE_CL</h4> 1520 1540 <p>Opcode: 33 (0x21)<br />
