Appeal No. 1998-2661 Application 08/633,267 always has meant to connote that the execution unit effectively "sees" a larger storage space than is physically actually available for use. Hence, the artisan would have clearly realized from Kau's prior art logical registers that the number of virtual rename buffers of claim 2 would have been larger in number than the actual physical rename registers. The discussion of pointers and lookup tables in the above-noted paragraph at column 2 of Kau renders obvious the subject matter of claim 3 on appeal. As to claim 8, appellants' admitted prior art at pages 2 and 3 indicate that architected registers are known in the art to be used with rename registers. Claim 8 does not define the number of architected registers with respect to the number of physical rename registers or the number of logical or virtual registers. As to claim 12, both Kau and appellants' admitted prior art indicate that plural execution units are known to be a part of superscaler computer systems. Turning to method independent claim 13, we apply this new rejection for the reasoning set forth with respect to claims 1 through 3, 8 and 12. Claim 13 is broader in one respect than 9Page: Previous 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 NextLast modified: November 3, 2007
