Abstract: A method for enabling and disabling Port Error detection and customizing corresponding error count threshold values. The method allows for adjustment of signal error verification thresholds before a connected port signals a loss of connection due to corrupted characters detected during normal operation and initialization on an IEEE-1394 serial bus. Also, the method customizes the limits for a Loss of Synchronization transition and reduces the probability for Bus Resets. Further, the method provides for a more stable bus operation, which is critical for usage in tight-looped and low-latency control systems.

Abstract: A data producer stores input data in a buffer in response to a slow clock signal and provides read data from the buffer in response to a read pointer signal. A data movement circuit reads the input data from the buffer using the read pointer signal and provides an update read pointer signal in response to reading the input data. The data movement circuit operates in response to a fast clock signal, and includes a metastable-free synchronizer circuit having inputs for receiving the update read pointer signal, the slow clock signal, and the read pointer signal, and an output for providing a synchronized read pointer signal equal to the read pointer signal except between a change in the read pointer signal while the slow clock signal is active until an inactivation of the slow clock signal. The buffer provides the read data in response to the synchronized read pointer signal.

The tracks are indicated at positions in the cache list with respect to the determined insertion points.

Abstract: A method for processing data read/write includes receiving a data read/write request. The data read/write request includes a command type, data, an address, a resource identifier, and a priority level. If the read/write request is the read request, determining whether the read request meets a first placement rule, the first rule being that the address of the read request is different from any and all write request addresses in the write command queue. If the first placement rule is not satisfied, the data stored in the conflicting (i.e., duplicated) address of the write request in the write command queue is acquired as the read data. A data read/write processing apparatus and a computer readable medium related to the data read/write processing method are also disclosed.

Abstract: Techniques and mechanisms for communicating packets of image information, the packets each having a respective format that is defined or otherwise indicated by a camera serial interface standard. In an embodiment, circuitry of a first physical layer (PHY) is operated to facilitate such communication via a lane of an interconnect that is coupled between the first PHY and a second PHY. The PHYs further communicate between each other a packet delimiter sequence between two such packets. In another embodiment, the plurality of packets and the packet delimiter sequence are communicated after a transition of one PHY from a relatively low power state, and prior to any subsequent transition of that PHY back to the relatively low power state. The camera serial interface standard specifies or otherwise indicates a protocol whereby a transition to such a low power state is performed between the respective communications of any two successive packets.

The memory space is divided into a plurality of memory regions. The address generation unit generates a cache memory address from a memory address specified by an external access request, based on a memory region among the plurality of memory regions which is associated with the memory address specified by the access request. A main unit is searched according to the cache memory address, thereby searching and replacing different ranges of cache lines for different memory regions.

Abstract: Techniques are disclosed for tracking memory page accesses in a unified virtual memory system. An access tracking unit detects a memory page access generated by a first processor for accessing a memory page in a memory system of a second processor. The access tracking unit determines whether a cache memory includes an entry for the memory page. If so, then the access tracking unit increments an associated access counter. Otherwise, the access tracking unit attempts to find an unused entry in the cache memory that is available for allocation. If so, then the access tracking unit associates the second entry with the memory page, and sets an access counter associated with the second entry to an initial value. Otherwise, the access tracking unit selects a valid entry in the cache memory; clears an associated valid bit; associates the entry with the memory page; and initializes an associated access counter.
