The present invention relates to a system for network-on-chip power management. The system comprising a primary network-on-chip comprises multiple components, each component having a power controller, characterized by a secondary network-on-chip comprises a secondary network-on-chip master node and a plurality of secondary network-on-chip nodes connected thereto, the plurality of secondary network-on-chip nodes associated to the components of the primary network-on-chip for power managing individual and link components of the primary network-on-chip, and a power management unit connected to the secondary network-on-chip master node, configured to polling status registers of the components of the primary network-on-chip for accessing power states of each component, accessing routing information of the components of the primary network-on-chip and sending request to the secondary network-on-chip nodes for powering on or off the associated components of the primary network-chip through the power controller. A method for network-on-chip power management is also disclosed herein.

System and a method for network-on-chip power management

The present invention relates a network-on-chip (NoC) system for optimizing data transfer, the system comprising a plurality of nodes including a source node and a destination node; characterized by a plurality of routers attached to the plurality of nodes that route a plurality of data packets from the source node to the destination node; wherein each of the plurality of packets is tagged with a routing information (RINFO), each node is assigned with a node unique identifier (ID) and each router is assigned with a router unique identifier (RID) for each horizontal and vertical routing direction for 2D and 3D interconnect topologies; wherein each of the router comprising at least a pair of ingress port and egress port, a route decoder and an arbiter to support a synchronous, an asynchronous and a source-synchronous operations. The present invention also relates to a method of optimizing data transfer using the NoC system.

Network-on-chip system for optimizing data transfer

A memory controller for improving data integrity and providing data security. The memory controller including a transmit data path to transmit write data to a memory device, the transmit data path comprising a scrambling component, wherein the scrambling component includes a scrambling logic and an exclusive OR logic, wherein the write data is divided into a first portion and a second portion, wherein input of the scrambling logic comprises the first portion of the write data and an address associated with the write data to generate a pseudo-random output, and wherein input of the exclusive OR logic comprises the second portion of the write data, the pseudo-random output and a fixed seed corresponding to the first portion of the write data to generate a scrambled data.

Memory controller for improving data integrity and providing data security and a method of operating thereof

A method comprises the steps of receiving input from a user via user interface and selecting a plurality of flits from a plurality of ingress into a plurality of virtual channels followed by selecting the flits from the virtual channels into a plurality of egress based on the input from the user. The selection of the flits into the virtual channels and the egress characterized by the steps of computing default and elevated bandwidths of the virtual channels, computing default and elevated weights of the virtual channels based on the default and elevated bandwidths and generating a weightage lookup table using the default and elevated weights to perform arbitration weightage lookup for the flits with default and elevated priority levels for selecting the flits into the virtual channels and the egress, wherein the flits from the different ingress comprise different default and elevated weight.

Method and a system for network-on-chip arbitration

A memory controller system (and method of pre-scheduling memory transaction) for a storage device comprising a linked-list controller; a plurality of command buffers to store read commands or write commands, and an arbiter to issue command. Each command buffer containing variables set by the linked-list controller. The linked-list controller is configured to execute commands in sequence independent of logical command buffer sequence. The command buffer is configured to support read commands with maximum number of write commands. The linked-list controller is configured to merge multiple write commands that are going to the same address and snarfs read commands from write commands if both commands are going to the same address and the read commands that are snarfed are loaded into a separate command buffer. The variables contained in each of the command buffer indicates status and dependency of the command buffer to create a link forming a command sequence.

Memory controller system and a method of pre-scheduling memory transaction for a storage device

A memory controller system comprising a scheduling module, a data buffer module, a global order buffer module and a linked-list controlling module. The linked-list controlling module is configured to receive and process a first command comprising a write command or a read command. The linked-list controlling module constructs at least one linked-list head based on scheduling dependencies and determines whether the first command is dependency-hit by comparing the first command with the existing commands buffered in the global order buffer module. If the first command is dependency-hit, the linked-list controlling module is configured to trigger a write merging process or a read snarfing process.

Memory controller system and a method for memory scheduling of a storage device

A device and method of clock synchronization for external memory interface. The device, and method, generating a clock output from a phase lock loop block via a sub-module clocking component; multiplexing the clock output through a global clock into different clock domains; clocking the data and an address or a command path by each clock domain; clocking the phase compensation FIFO by clock domain and clock phase alignment clock; generating the pointer for the phase compensation FIFO from central pointer generator block; and synchronizing the pointer of the adjacent intellectual property module with a parent intellectual property module.
