US 12,541,453 B2 · Reconfigurable shared memory systems, and related processor-based systems and methods

Abstract

Reconfigurable shared memory systems, and related processor-based systems and methods are disclosed. The reconfigurable shared memory system can be included in a processor-based system to provide memory for data storage. In exemplary aspects, the reconfigurable shared memory system not only includes the dedicated memory and the general memory (e.g., system cache memory), but also includes a reconfigurable memory. The reconfigurable memory can be configured as either part of addressable memory space of the dedicated memory if an application requires such additional dedicated memory, and/or configured as part of the addressable memory space of the general memory to provide additional memory to other clients for increased processing performance if such reconfigurable memory is not needed as part of the dedicated memory. The dedicated memory does not have to be sized to the worst-case size requirements of a given application.

Dependent claims

A memory system in a processor-based system, comprising:

a general memory having a first memory address space addressable by each of a plurality of processing units in the processor-based system;
a dedicated memory having a second memory address space exclusively addressable by a subset of processing units from the plurality of processing units;
a reconfigurable memory having a third memory address space;
and
a reconfiguration memory direction circuit coupled to reconfigurable memory, the reconfiguration memory direction circuit configured to:
assign the third memory address space of the reconfigurable memory to the first memory address space of the general memory, in response to a reconfigurable memory configuration for the reconfigurable memory indicating a general memory mapping configuration;
and
assign the third memory address space of the reconfigurable memory to the second memory address space of the dedicated memory, in response to the reconfigurable memory configuration for the reconfigurable memory indicating a dedicated memory mapping configuration.

5 more elements

A method of reconfiguring a reconfigurable memory as part of an addressable address space of another memory in a memory system in a processor-based system, comprising:

determining a third memory address space of a reconfigurable memory as being assigned to one of a general memory having a first memory address space addressable by each of a plurality of processing units in the processor-based system and a dedicated memory having a second memory address space exclusively addressable by a subset of processing units of the plurality of processing units;
assigning the third memory address space of the reconfigurable memory to the first memory address space of the general memory, in response to determining the third memory address space is assigned to the general memory;
and
assigning the third memory address space of the reconfigurable memory to the second memory address space of the dedicated memory, in response to determining the third memory address space is assigned to the dedicated memory.
