摘要： An integrated circuit may include a memory controller serving as an interface between master processing modules and system memory. The master processing modules may provide memory access requests to the memory controller along with respective tag identifications. The memory controller may place the memory access requests in a queue for fulfillment. The memory controller may include a merging module that generates a memory access request to replace two or more memory access requests previously received from the master processing modules. The merging module may store information associated with the memory access requests that were merged and use the stored information to assign appropriate tag identifications to portions of data obtained from system memory when fulfilling the generated memory access request. The memory controller may include a verification module that can be used with test equipment to optimize the design of the master processing modules for improved memory access performance.

摘要： A method and system for operating a multi-port memory system are disclosed. A memory controller may service read requests by accessing requested data from an external memory and communicating it to the requesting memory ports for access by devices coupled to the memory ports. A shared memory of the memory controller may be used to temporarily store data if a buffer associated with a requesting device is full. To reduce the ability for a slower memory port to occupy the shared memory and cause faster memory ports to be underserviced, the memory controller may advantageously regulate or limit issuance of read requests by memory ports operating at slower clock frequencies. The memory ports may be regulated independently of one another based on at least one respective attribute of each memory port, at least one attribute of the external memory, etc.

摘要： A programmable integrated circuit may have a memory controller that interfaces between master modules and system memory. The memory controller may receive memory access requests from the masters via ports that have predetermined bit widths. To provide the memory controller with adjustable port widths, a mapping interface may be provided that interfaces between master processing modules and the memory controller. The mapping interface may allocate port resources such as read data ports and write data ports of the memory controller to each master processing module. The mapping interface may assign a desirable number of read data ports and write data ports to each master to accommodate the requirements of that master. The mapping interface may assign a command port to each master that receives memory access requests from that master. The mapping interface may convey write acknowledgements in response to fulfilling write access requests.

摘要： An integrated circuit may have a memory controller that interfaces between master processing modules and system memory. A scheduling module may be used to handle memory access requests received from multiple master modules. The scheduling module may arrange the received memory access requests in an order for fulfillment with system memory. A bypass module may be used to provide a low latency bypass path that allows memory access requests to bypass the scheduling module. The bypass module may include an eligibility detection module that identifies memory access requests eligible for scheduler bypassing, a port selection module that provides a low latency bypass path for the eligible memory access requests, multiplexing circuitry that selects between memory access requests provided from the low latency bypass path and from the output of the scheduling module, and a masking module that prevents redundant fulfillment of memory access requests.

摘要： A programmable integrated circuit may have a memory controller that interfaces between master modules and system memory. The memory controller may receive memory access requests from the masters via ports that have associated priority values and fulfill the memory access requests by configuring system memory to respond to the memory access requests. To dynamically modify the associated priority values while the memory controller receives and fulfills the memory access requests, a priority value update module may be provided that dynamically updates priority values for the memory controller ports. The priority value update module may provide the updated priority values with update registers that are updated based on an update signal and a system clock. The priority values may be provided by shift registers, memory mapped registers, or provided by masters along with each memory access request.

摘要： Systems or methods of the present disclosure may provide a programmable logic device including a network-on-chip (NoC) to facilitate data transfer between one or more main intellectual property components (main IP) and one or more secondary intellectual property components (secondary IP). To reduce or prevent excessive congestion on the NoC, the NoC may include one or more traffic throttlers that may receive feedback from a data buffer, a main bridge, or both and adjust data injection rate based on the feedback. Additionally, the NoC may include a data mapper to enable data transfer to be remapped from a first destination to a second destination if congestion is detected at the first destination.
