- Can somebody provide me with comments or references to pros and
- cons of having a large register set on-chip. Lets say 64 Int and
- 64 FP registers be it 32-bit or 64-bit.
-
- THere is a fairly recent paper by some fellows at HP, entitled
- something like "Graphics Extensions to the HP Precision Architecture",
- where they described increasing the number of single precision FP
- registers to 58 by placing two SP numbers in one DP register. They
- said that some 3D graphics inner loops have more than enough live
- variables to benefit.
-
- I believe that it was a COMPCON paper. Sorry, no more accurate
- reference: if you saw the pile of papers "to be filed" in my office,
- you'd understand.
