Abstract: Traditionally, providing parallel processing within a multi-core system has been very difficult. Here, however, a system is provided where serial source code is automatically converted into parallel source code, and a processing cluster is reconfigured “on the fly” to accommodate the parallelized code based on an allocation of memory and compute resources. Thus, the processing cluster and its corresponding system programming tool provide a system that can perform parallel processing from a serial program that is transparent to a user. Generally, a control node connected to the address and data leads of a host processor uses messages to control the processing of data in a processing cluster. The cluster includes nodes of parallel processors, shared function memory, a global load/store, and hardware accelerators all connected to the control node by message busses. A crossbar data interconnect routes data to the cluster circuits separate from the message busses.

Abstract: Systems and methods for discrete power control of components within a computer system are described herein. Some illustrative embodiments include a system that includes a subsystem with a plurality of components (configurable to operate at one or more power levels), a control register (coupled to the plurality of components) including a plurality of bits (each uniquely associated with a one of the plurality of components), and a power controller coupled to, and configurable to cause, the plurality of components to operate at the one or more power levels. The power controller asserts a signal transmitted to the subsystem, commanding the subsystem to transition to a first power level. A first of the plurality of components, associated with an asserted bit of the control register, operates at a second power level corresponding to a level of power consumption different from that of the first power level indicated by the power controller.

Abstract: Apparatus and methods are disclosed herein that provide reduced bus transaction latency on a bus architecture that includes at least one master coupled to a plurality of slaves. As disclosed herein, a device (e.g., a slave) may include bus logic and host logic coupled to the bus logic. The bus logic may obtain a serialization token permitting the host logic to complete a transaction received by the bus logic via the bus. Further, the bus logic may keep the serialization token to complete at least one other transaction.
