摘要： A soft-function trigger state machine includes state machine logic defined to use a scan-in waveform to sample a scan-clock waveform to obtain a sampled data pattern. The state machine logic is defined to compare the sampled data pattern to a soft action pattern to determine whether the sampled data pattern matches the soft action pattern. The state machine logic is also defined to trigger an action associated with the soft action pattern when the sampled data pattern matches the soft action pattern.

摘要： An integrated circuit chip includes a scan-in pin, a scan clock pin, and a test controller. The scan-in pin and the scan clock pin receive a test program for the type of test mode and a soft-reset pattern. A state machine is configured to direct sampling of a scan clock waveform provided through the scan clock pin as dictated by transitions of a scan-in waveform provided through the scan-in pin. The state machine identifies a bit match from the sampled scan clock waveform upon executing the soft-reset pattern. The identified bit match triggers a soft reset which eliminates the need for an extra reset pin, when testing in scan mode.

摘要： An integrated circuit chip having testing logic for testing circuitry of the integrated circuit chip is provided. The integrated circuit chip includes at least a scan-in pin, a scan clock pin, and a test controller. The test controller has test mode registers for storing a type of test mode to be executed, and the test controller accepting signals from the scan-in pin and the scan clock pin. The scan-in pin and the scan clock pin receiving a test program for the type of test mode and a soft-reset pattern. Also included is a state machine logic that is part of the integrated circuit chip. The state machine logic, during execution of the test program, being configured to direct sampling of a scan clock waveform provided through the scan clock pin as dictated by transitions of a scan-in waveform provided through the scan-in pin. The sampling by the state machine circuitry identifying a bit match from the sampled scan clock waveform upon executing the soft-reset pattern. The identified bit match triggering a soft reset by updating the test mode registers of the test controller. The soft reset therefore eliminates the need for an extra reset pin, when testing in scan mode. The communication channel defined through the use of the scan-in and scan clock pins can be used to trigger other soft actions.

摘要： First and second data interfaces provide data transfer to and from a plurality of memory banks. The first data interface uses a first bus size and a first clock frequency. The second data interface uses a second bus size and a second clock frequency. The second bus size is an integer multiple of the first bus size. The first clock frequency is an integer multiple of the second clock frequency. A channelizer module segments data from the second data interface into data segments of the first bus size and transmits them to addressed ones of the plurality of memory banks using the first clock frequency. The channelizer module also receives data in accordance with the first bus size and first clock frequency from the plurality of memory banks, combines this data into the second bus size, and transmits the data to the second data interface using the second clock frequency.
