A device, comprising a first interpolator that is configured to (a) receive, at a first clock rate, a first signal having a first sampling rate and (b) output, at a second clock rate, a second signal having a first desired sampling rate average; wherein the first interpolator comprises: a first buffer for storing the first signal; and a first fractional sampling ratio circuit that is configured to generate a first pattern of fixed point values, wherein an average value of the first pattern corresponds to a first desired sampling rate ratio between the first desired sampling rate average and the first sampling rate.

Efficient drift avoidance mechanism for synchronous and asynchronous digital sample rate converters

Described embodiments process multiple threads of commands in a network processor. One or more tasks are generated corresponding to each received packet, and the tasks are provided to a packet processor module (MPP). A scheduler associates each received task with a command flow. A thread updater writes state data corresponding to the flow to a context memory. The scheduler determines an order of processing of the command flows. When a processing thread of a multi-thread processor is available, the thread updater loads, from the context memory, state data for at least one scheduled flow to one of the multi-thread processors. The multi-thread processor processes a next command of the flow based on the loaded state data. If the processed command requires operation of a co-processor module, the multi-thread processor sends a co-processor request and switches command processing from the first flow to a second flow.

Multi-threaded processing with hardware accelerators

An apparatus comprising a first core of a multi-core processor, a second core of a multi-core processor and a bus matrix. The first core may be configured to communicate through a first input/output port. The first core may also be configured to initiate a testing application. The second core may be configured to communicate through a second input/output port. The second core may also be configured to respond to the testing application. The bus matrix may be connected to the first input/output port and the second input/output port. The bus matrix may transfer data between the first core and the second core. The testing application may generate real-time statistics related to the execution of instructions by the second core.
