# Dynamic accuracy CSR <a name="dynamic"></a>
+FCSR to be modified to include accuracy bits:
+
| 31....11 | 10..8 | 7..5 | 4....0 |
| -------- | ------ | ---- | ------ |
| reserved | facc | frm | fflags |
-[[!table data="""
-| facc | mode | description |
+The values for the field facc to include the following:
+
+| facc | mode | description |
+| ----- | ------- | ------------------- |
| 0b000 | IEEE754 | correctly rounded |
| 0b010 | ULP<1 | Unit Last Place < 1 |
| 0b100 | Vulkan | Vulkan compliant |
-| 0b110 | Appx | Machine Learning |
-"""]]
+| 0b110 | Appx | Machine Learning |
maybe a solution would be to add an extra field to the fp control csr
to allow selecting one of several accurate or fast modes:
