Abstract: A system is presented that includes a communication link, a runtime processor coupled to the communication link, and a reconfigurable processor. The reconfigurable processor is adapted for generating an interrupt to the runtime processor in response to a predetermined event and includes multiple arrays of coarse-grained reconfigurable (CGR) units and an interface to the communication link that couples the reconfigurable processor to the runtime processor via the communication link. The runtime processor is adapted for configuring the interface to the communication link to provide access to the multiple arrays of coarse-grained reconfigurable units from a physical function driver and from at least one virtual function driver, and the reconfigurable processor is adapted for sending the interrupt to the physical function driver and to a virtual function driver of the at least one virtual function driver within the runtime processor.

Abstract: A reconfigurable dataflow unit (RDU) includes an intra-RDU network, an array of configurable units connected by an array level network and function interfaces. The RDU also includes interface circuits coupled between the intra-RDU network and external interconnects. An interface circuit receives a packet from the external interconnect and extracts a target RDU identifier and compares the target RDU identifier to the value of the identity register. It also communicates over the intra-RDU network to a function interface based on information in the first packet in response to the target RDU identifier being equal to the identity register. The interface circuit retrieves another interface circuit identifier for the target RDU identifier from the pass-through table and, in response to the target RDU identifier not being equal to the identity register, sends the target RDU identifier and other information to the other interface circuit over the intra-RDU network.

The second core may be configured to disable the first core from further processing instructions of the subset responsive to receiving the indication, and to copy data from the first core to a third core responsive to disabling the first core. The third core may be configured to resume processing the subset dependent upon the data.

Abstract: An array of memory cells includes a scan chain with one or more chain segments of storage memory cells. Chain segments are separated by chain buffer memory cells. Memory cells of each chain segment are coupled with a sequence generator that generates a sequence of non-overlapping pulses from a pulse in a scan clock (SCLK) signal. The duration of the sequence equals at most a cycle of the SCLK signal. The scan chain applies the pulses to the memory cells backwards starting from the chain buffer memory cell. Memory cells may include a single latch. The array of memory cells may be included in a semiconductor memory subsystem. A scan chain that has a fault condition may be repaired by rerouting the scan chain to avoid the location of the fault condition and to add one or more redundant chain segments.

The bottom-cap further includes one or more auxiliary ports for injecting a reagent when the lid apparatus is in a closed configuration sealingly attached to the multi-chambered sample container.

Abstract: A method is disclosed for scanning an array of memory cells arranged in rows and columns, where the array includes a scan chain partitioned into multiple sections. Each section includes a first scan multiplexer, a section buffer cell, and multiple memory cells. The method includes determining whether a scan shift mode is entered, asserting a scan enable signal to select second inputs of each first scan multiplexer when the scan shift mode is entered, coupling the scan input with the input of the section buffer cell of the first section, and coupling the output of the memory cell in the previous section with the input of the section buffer cell in the next section. The method further includes updating the contents of the section buffer cell and the memory cells using clock signals and scan word line pulses.

Abstract: A computing system is disclosed, comprising a host computer and multiple CGRPs (coarse-grained reconfigurable architecture processors) connected to the host computer through external communication links. Each CGRP includes an internal network, external interface circuits, memory interface circuits, arrays of configurable units, hang detection circuits, force-quit controllers, and a network recovery circuit with control registers. The host computer is programmed to configure and execute applications across the arrays of configurable units in both CGRPs. In case of a hang detection in one CGRP, the network recovery circuit initiates a force quit process and notifies the host computer. Additionally, the network recovery circuit compares application IDs and halts execution in the other CGRP if necessary. This system provides efficient failure tolerance and recovery mechanisms for parallel processing applications.

Abstract: A processor includes an internal network with separate packet-switching networks for request, response, data, and credit transmission. Each of the four networks includes switches interconnected by links. Interface circuits connect the internal network to communication links or electronic memory and communicate over the internal network. A network recovery circuit is also coupled to the internal network. Each switch has ports, buffers for input packets, routing circuitry to send packets to output ports based on destinations, and a watchdog timer to detect packet timeouts and notify the network recovery circuit of delays. The network recovery circuit responds to timeout messages by setting a network failure condition, ensuring efficient and reliable network operation.

Abstract: A Coarse-grained Reconfigurable Processor (CGRP) includes an internal network with request, response, and data networks operating concurrently as separate packet-switched networks. The CGRP includes external interface circuits coupled to an interface configurable unit in an array of configurable units through the internal network. The CGRP also includes a network health monitor circuit that is configured to detect network failure conditions by writing and then reading health monitor registers across the internal network.

Abstract: A coarse-grained reconfigurable architecture processor is disclosed, featuring an array of configurable units capable of executing an application with defined progress milestones. The processor includes a control bus connecting the configurable units and a hang detection circuit with a timer that resets upon receiving a control signal via the control bus. Upon reaching a progress milestone, a configurable unit sends a control signal to the hang detection circuit via the control bus. The hang detection circuit monitors the application's execution for hang conditions by detecting timer expiration, ensuring efficient and reliable processing of applications on the reconfigurable processor.

Abstract: A processor has multiple memory interfaces and a memory interleaver controlling access to the memory interfaces. The memory interfaces may each couple with one or more memory devices. The number of memory devices coupled to the different memory interfaces may be unequal. The memory interleaver determines a memory region from a logical address, and a region relative address. It determines the interleave factor IF corresponding to the memory region. It performs an integer division to obtain a device line address, and a modulo operation to obtain an uncorrected channel address. The memory interleaver may add a region start address associated with the memory region to the device line address to obtain a physical line address. It may correct the uncorrected channel address, based on the memory region, to obtain a physical channel address. Some implementations use configuration memories to allow flexibility, other implementations are hardwired for a particular memory architecture.
