| 41. | Two register file write ports are used to write results from the two integer functional units.
|
| 42. | The decoded stack instructions are mapped into one or more sequential actions on that hidden register file.
|
| 43. | During the third stage ( RF ), the instruction is decoded and the register file is read.
|
| 44. | A major architectural mistake was that both integer instructions and floating-point instructions used the same register file.
|
| 45. | The integer register file provides registers to two arithmetic logic units and the load / store unit.
|
| 46. | Some third-party x86 equivalent processor even became noncompetitive to ARM due having no dedicated register file architecture.
|
| 47. | Although the current term " register file " shows the early concept of files, it has largely disappeared.
|
| 48. | The register file has four read ports and two write ports evenly divided between the two integer pipelines.
|
| 49. | Unlike ARM processor on the other hand does not integrate multiple register files to load / fetch instructions.
|
| 50. | Two data buses write data from the register file to the two CACHE dies that implement the data cache.
