Embodiment Construction

[0010] It should be understood that the components of the embodiments generally described herein and shown in the drawings may be arranged and designed in many different configurations. Accordingly, a more detailed description of various embodiments shown in the drawings is not intended to limit the scope of the present disclosure, but is merely representative of various embodiments. While the various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

[0011] The described embodiments are to be considered in all respects as illustrative only and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by this detailed description. All changes that come within the meaning and range of equivalency of the claims are intended to be embraced therein.

[0012] Throughout this specification, references to features, advantages, or similar language do not ...

Abstract

System and method for allocating memory resources are disclosed. The system utilizes a bus system coupled to a plurality of requestors and a plurality of memory systems coupled to the bus system. Each memory system includes a memory component and a memory management module including a value that represents access rights to the memory component. The memory management module is configured to receive an access request from a first requestor of the plurality of requestors and to grant access to the memory component only if the value indicates that the first requestor has access rights to the memory component. The memory management module is configurable to change the value to give the access rights to the memory component to a second requestor of the plurality of requestors.

Description

technical field [0001] The present invention relates to memory, and more particularly to systems and methods for allocating memory resources. Background technique [0002] In a computing system (eg, a system-on-chip (SoC) integrated circuit), there are typically multiple bus masters, each possibly running at a different clock speed. The partitioning of memory resources is done at the design stage of an integrated circuit to allocate memory resources to masters and thus to specific clocks. In order to interface a master device with a memory resource, wherein the master device operates with a clock that is not local to the master device, a bridge is usually required. However, this introduces undesirable latency when accessing memory resources. In a typical system including multiple masters, it is not possible to dynamically allocate memory resources. Contents of the invention [0003] A system for allocating memory resources according to an embodiment of the present inven...
