摘要： A method for operating a host device includes comparing a predetermined response of a peripheral device to a response token received from the peripheral device. The predetermined response and the response token are generated based on a first command transmitted from the host device to the peripheral device. The method further includes controlling a transfer of first data from a first memory to a peripheral control module based on the comparison between the predetermined response and the response token without interrupting a host control module, and selectively passing interrupts to the host control module when the predetermined response does not match the response token.

摘要： Controlling access to memory includes receiving a plurality of memory access requests and assigning corresponding time values to each. The assigned time values are adjusted based upon a clock pulse and a priority access list is generated. Factors consider include missed access deadlines, closeness to missing access deadlines, and whether a page is open. The highest ranked client is then passed to a sequencer to allow the requested access. Time values may be assigned and adjusted according to client ID or client type (latency or bandwidth). A plurality of power modes of operation are defined wherein operation in a selected power mode of operation is based at least in part on the assigned or adjusted time values. The processing is performed in hardware in parallel (at the same time) by associated logic circuits.

摘要： In some embodiments, a method for supporting multiple devices on a high speed physical link may be described. An embedded device may assert a link request pin to request to transmit data on a multi-point communications link that may serve a plurality of embedded devices. A controlling device may receive the link request signal. When the controlling device finishes sending data on the link, it may address the plurality of embedded devices in a round robin format and may determine which device asserted the link request pin. The embedded device that asserted the link request pin may send an acknowledgement signal to the controlling device when it is addressed.

摘要： In one embodiment the present invention includes a method and apparatus for enabling a main core and one or more co-processors to operate in a de-coupled mode, thereby facilitating the execution of two or more instruction threads in parallel. A co-processor, according to an embodiment of the invention, has a coupling manager including a loop buffer for storing instructions which can be independently fetched and executed by the co-processor when operating in de-coupled mode. In addition, the coupling manager includes a loop descriptor and a counter/condition descriptor. The loop descriptor and condition descriptor work in conjunction with one another to determine what, if any, action should be taken when a co-processor is in a particular processing state, for example, as indicated by a counter keeping track of loop processing.
