Static identifications in object-based memory access
A computer system having an address system of a first predetermined width in which each address of the first predetermined width in the address system includes a first portion identifying an object and a second portion identifying an offset relative to the object, where a static identifier for the first portion is predetermined to identify an address space having a second predetermined width that is smaller than the first predetermined width, or a space of kernel objects.
1 . A computer system, comprising:
a register of a first predetermined width, the register storing an address having:
a first portion identifying an object; and
a second portion identifying an offset relative to the object, wherein the offset is utilized for loading an instruction from a memory location; and
an execution unit configured to load the instruction using the offset and execute the instruction using the address in accessing memory;
wherein the first portion has a static identifier used in executing the instruction and configured to identify a predetermined object type of the object to facilitate adjusting of at least one operation conducted by a processor in accordance with the predetermined object type.
2 . The computer system of claim 1 , wherein the static identifier is configured to represent a class of objects; and the class of objects is applications using an address space having a second predetermined width that is smaller than the first predetermined width.
3 . The computer system of claim 2 , wherein the first predetermined width is 128 bits; and the second predetermined width is one of: 64 bits and 32 bits.
4 . The computer system of claim 3 , wherein when the static identifier has a value of one, the second predetermined width is 64 bits.
5 . The computer system of claim 3 , wherein when the static identifier has a value of one, the second predetermined width is 32 bits.
6 . The computer system of claim 2 , wherein the static identifier is pre-associated with a predetermined property used in address conversion during executing instructions of the object.
7 . The computer system of claim 6 , wherein the address conversion includes converting the address from the second predetermined width to the first predetermined width.
8 . The computer system of claim 7 , wherein the converting of the address from the second predetermined width to the first predetermined width is performed using the static identifier as an object identifier and the address of the second predetermined width as an offset.
9 . The computer system of claim 1 , wherein the static identifier is configured to represent a class of objects; and the class of objects is in a kernel of an operating system of the computer system.
10 . The computer system of claim 9 , wherein the static identifier has a value of zero.
11 . The computer system of claim 1 , wherein the instruction is loaded using the address for execution.
12 . The computer system of claim 1 , wherein execution of the instruction operates on a data item obtained from a memory location identified by the address.
13 . The computer system of claim 2 , wherein the static identifier is pre-associated with a predetermined property used to adjust a security operation during executing instructions of the object.
14 . The computer system of claim 2 , wherein the static identifier is pre-associated with a predetermined property used to adjust a priority during executing instructions of the object.
15 . A method, comprising:
receiving, in a processor, a first address in a memory address space having a first predetermined width;
determining, by the processor, an identifier predefined to represent the memory address space and configured to identify a predetermined object type of an object associated with the first address to facilitate adjusting of at least one operation conducted by the processor in accordance with the predetermined object type; and
combining, by the processor, the predefined identifier and the first address to generate a second address having a second predetermined width larger than the first predetermined width, wherein the second address has an object identifier portion and a byte offset portion, and the object identifier portion of the second address contains the predefined identifier representing the memory address space and the byte offset portion of the second address corresponds to the first address.
16 . The method of claim 15 , wherein the second predetermined width is 128 bits; and the first predetermined width is one of: 64 bits and 32 bits.
17 . The method of claim 16 , wherein the object identifier portion of the second address has 64 bits; and the byte offset portion of the second address has 64 bits.
18 . A computer system, comprising:
a memory address system of a first predetermined width in which each memory address of the first predetermined width in the memory address system includes an object identifier portion and an offset portion,
wherein the offset is utilized for loading an instruction from a memory location,
wherein an execution unit in the computer system is configured to load the instruction using the offset and execute the instruction using a memory address of the memory address system in accessing memory.
19 . The computer system of claim 18 , wherein the object identifier portion is pre-associated with an object property; and the object property identifies a kernel of an operating system.
20 . The computer system of claim 18 , wherein the object identifier portion is pre-associated with an object property; and the object property is configured to identify memory addresses of a second predetermined width that is smaller than the first predetermined width.
