Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102 of this title, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 1-25 are rejected under 35 U.S.C. 103 as being unpatentable over Kemisetti et al. (US 2024/0220425 A1), Okada (US 6,275,917 B1) and Roozbeh et al. (US 2018/0314453 A1).
Regarding claim 1, Kemisetti et al. discloses A method, comprising: configuring a memory for use in executing an application [abs, method for assigning secure memory ranges for applications], the configurating the memory including: defining a set of virtual memory resources associated with one or more contiguous memory areas of the memory [par. 0043, “(i) a range of non-secure virtual memory addresses 316 corresponding to non-secure memory resources 322, and (ii) a range of secure virtual memory addresses 318 corresponding to secure memory resources 320”]; wherein a security attribute assigned to a virtual memory resource indicates the virtual memory resource is a secure memory resource, a non-secure memory resource, or a non-secure callable memory resource [par. 0043, “(i) a range of non-secure virtual memory addresses 316 corresponding to non-secure memory resources 322, and (ii) a range of secure virtual memory addresses 318 corresponding to secure memory resources 320”]; merging contiguous virtual memory resources of the set of virtual memory resources [pars. 0047-0050, increasing secure memory virtual address range (merging contiguous virtual memory resources), “Because the memory command is secure, the UMD 204 may associate a virtual memory address from the secure memory range 318 with the memory command”].
Kemisetti et al. does not explicitly disclose selectively merging contiguous virtual memory resources of the set of virtual memory resources based on respective security attributes of the virtual memory resources of the set of virtual memory resources, generating a merged set of virtual memory resources.
However Okada teaches selectively merging contiguous virtual memory resources of the set of virtual memory resources based on respective security attributes of the virtual memory resources of the set of virtual memory resources, generating a merged set of virtual memory resources [col. 4, lines 20-22, “sections having the same memory protection attribute and continuous address space are merged in order to obtain a single section”, also see col. 5, lines 50-62].
Before the effective filing date of the claimed invention, it would have been obvious to a person having ordinary skill in the art to incorporate the teaching of Okada into the teaching of Kemisetti et al. with the motivation such that sections allocated to continuous address space are merged so that it is possible to easily realize memory management as taught by Okada [Okada: col. 4, lines 20-25].
They do not explicitly disclose storing configuration information indicative of the merged set of virtual memory resources.
However, Roozbeh et al. teaches storing configuration information indicative of the merged set of virtual memory resources [par. 0070, after memory merging, updating the address translation tables (storing configuration information)].
Before the effective filing date of the claimed invention, it would have been obvious to a person having ordinary skill in the art to incorporate the teaching of Roozbeh et al. into the teaching of Kemisetti et al. and Okada with the motivation such that requests to access to the memory will be redirected to an address range of memory as taught by Roozbeh et al. [Roozbeh et al.: par. 0070].
Regarding claim 2, the rejection of claim 1 is incorporated.
Roozbeh et al. further teaches the information indicative of the merged set of virtual memory resources comprises configuration data values for one or more memory ranges of the memory [par. 0070, after memory merging, updating the address translation tables (storing configuration information), requests to access to the shared part of memory will be redirected to an address range (configuration data values) of shared memory].
Before the effective filing date of the claimed invention, it would have been obvious to a person having ordinary skill in the art to incorporate the teaching of Roozbeh et al. into the teaching of Kemisetti et al. and Okada with the motivation such that requests to access to the memory will be redirected to an address range of memory as taught by Roozbeh et al. [Roozbeh et al.: par. 0070].
Regarding claim 3, the rejection of claim 2 is incorporated.
Kemisetti et al. further disclose the configuration data values include memory addresses and security attribute values [par. 0043, “(i) a range of non-secure virtual memory address 316 corresponding to non-secure memory resources 322, and (ii) a range of secure virtual memory addresses 318 corresponding to secure memory resources 320”, par. 0049, non-secure page table or secure page table].
Regarding claim 4, the rejection of claim 1 is incorporated.
Kemisetti et al. further disclose a security attribute indicating the contiguous virtual memory resources are non-secure memory resources [par. 0043, “a range of non-secure virtual memory address 316 corresponding to non-secure memory resources 322”, par. 0039, “if the command is to non-secure memory, the UMD 204 may determine a 32-bit virtual memory address from a range of 32-bit virtual memory addresses corresponding to non-secure memory resources”].
Okada teaches selectively merging comprises merging contiguous virtual memory resources of the set of virtual memory resources having a same security attribute indicating the contiguous virtual memory resources [col. 4, lines 20-22, “sections having the same memory protection attribute and continuous address space are merged in order to obtain a single section”, also see col. 5, lines 50-62].
Before the effective filing date of the claimed invention, it would have been obvious to a person having ordinary skill in the art to incorporate the teaching of Okada into the teaching of Kemisetti et al. with the motivation such that sections allocated to continuous address space are merged so that it is possible to easily realize memory management as taught by Okada [Okada: col. 4, lines 20-25].
Regarding claim 5, the rejection of claim 4 is incorporated.
Kemisetti et al. further disclose a security attribute indicating the contiguous virtual memory resources are non-secure memory resources or non-secure callable memory resources [par. 0043, “a range of non-secure virtual memory address 316 corresponding to non-secure memory resources 322”, par. 0039, “if the command is to non-secure memory, the UMD 204 may determine a 32-bit virtual memory address from a range of 32-bit virtual memory addresses corresponding to non-secure memory resources”].
Okada teaches the selectively merging comprises merging contiguous virtual memory resources of the set of virtual memory resources having security attributes indicating the contiguous virtual memory resources [col. 4, lines 20-22, “sections having the same memory protection attribute and continuous address space are merged in order to obtain a single section”, also see col. 5, lines 50-62].
