21. This case usually forces multiple copies of a register file , one for each datapath. 22. Some stack machines have a stack of limited size, implemented as a register file . 23. It has two integer units, two load store units and two integer register files . 24. The vector register file was multi-ported and contained three write ports and five read ports. 25. Other architectures that include similar register file features include Intel i960, IA-64, and AMD 29000. 26. The register file took up most of that space. 27. As mentioned earlier, the reservation station register files are usually small, with perhaps eight entries. 28. It had 44, 500 transistors implementing 31 instructions and a register file containing 78 32-bit registers. 29. The number of registers per register file was also considered, with 32 and 64 being contenders. 30. During the decode stage, one instruction was decoded, and its operands read from its register file .
