In some examples, first slot data that is indicated by the user during the dialog session may be determined. In various examples, data representing the first slot data may be stored in a database in association with the first natural language input.

Abstract: An apparatus includes a cache controller circuit and a cache memory circuit that further includes cache memory having a plurality of cache lines. The cache controller circuit may be configured to receive a request to reallocate a portion of the cache memory circuit that is currently in use. This request may identify an address region corresponding to one or more of the cache lines. The cache controller circuit may be further configured, in response to the request, to convert the one or more cache lines to directly-addressable, random-access memory (RAM) by excluding the one or more cache lines from cache operations.

Abstract: A non-transitory computer-readable medium is disclosed, the medium having instructions stored thereon that are executable by a computer system to perform operations that may include allocating a plurality of storage locations in a system memory of the computer system to a buffer. The operations may further include selecting a particular order for allocating the plurality of storage locations into a cache memory circuit. This particular order may increase a uniformity of cache miss rates in comparison to a linear order. The operations may also include caching subsets of the plurality of storage locations of the buffer using the particular order.

Additionally, a controller may manage reading and writing of the previously determined data to the provisioned section of the cache memory.

Abstract: Techniques are disclosed relating to merging virtual communication channels in a portion of a computing system. In some embodiments, a communication fabric routes first and second classes of traffic with different quality-of-service parameters, using a first virtual channel for the first class and a second virtual channel for the second class. In some embodiments, a memory controller communicates, via the fabric, using a merged virtual channel configured to handle traffic from both the first virtual channel and the second virtual channel. In some embodiments, the system limits the rate at which an agent is allowed to transmit requests of the second class of traffic, but requests by the agent for the first class of traffic are not rate limited. Disclosed techniques may improve independence of virtual channels, relative to sharing the same channel in an entire system, without unduly increasing complexity.

Abstract: Systems, apparatuses, and methods for dynamically partitioning a memory cache among a plurality of agents are described. A system includes a plurality of agents, a communication fabric, a memory cache, and a lower-level memory. The partitioning of the memory cache for the active data streams of the agents is dynamically adjusted to reduce memory bandwidth and increase power savings across a wide range of applications. A memory cache driver monitors activations and characteristics of the data streams of the system. When a change is detected, the memory cache driver dynamically updates the memory cache allocation policy and quotas for the agents. The quotas specify how much of the memory cache each agent is allowed to use. The updates are communicated to the memory cache controller to enforce the new policy and enforce the new quotas for the various agents accessing the memory.

Abstract: A system and corresponding method captures speculative and concurrent trace-data and trace-clock information from core processing units of a System on a Chip (SOC). An interface receives trace data from at least one core processing unit, and a storage array stores the trace data in two different modes of operation. In the first mode, which occurs prior to a predetermined operating state of the SOC, the storage array operates in a circular buffer mode in which the newest trace data overwrites the oldest trace data when the storage array becomes full In the second mode, which occurs after the predetermined operating state of the SOC, the storage array operates in a FIFO mode in which the newest trace data is written into the storage array and the oldest trace data contained in the storage array is output to a debug processing core unit of the SOC.

Abstract: A system and a method select a datapath through a meshed Input/Output (IO) fabric. A plurality of port controllers is coupled to interconnection logic. Each port controller is coupled to a corresponding communication link and outputs a detection signal if the corresponding communication link transitions from a first lower-power state to a second higher power state. The interconnection logic, responsive to the detection signal, is configured to output a first signal to one or more selected port controllers to transition the corresponding communication link coupled to the selected port controller from the first power state to the second power state based on a frequency of use of a datapath between the communication link corresponding to the port controller outputting the detection signal and the communication link corresponding to each of the one or more selected port controllers.
