摘要:
A most recently used bit (25) is used to determine if a data transfer should occur from a fill buffer (20) into a data memory (32) in a cache (15) If the data to be displaced in the data memory (32) has been referenced more recently than the data present in the fill buffer (20), then the transfer should not occur. When a cache miss does occur, a control register (50) is used to determine the conditions for loading the fill buffer (20).

摘要:
A processor may receive multiple signals corresponding to potential power faults. A control register in the processor may specify actions to be taken for each of the potential power faults.
摘要:
The present disclosure includes apparatus, systems, digital logic circuitry and techniques relating to data encoding. A method performed by a system on a chip (SOC) includes receiving data to be output to a memory unit external to the SOC. Also a key for scrambling the received data is received. A proper subset of the key is identified and used to scramble the received data. The scrambled data is output to the memory unit external to the SOC.
摘要:
An indication that a power supply is ramped up to a threshold level is received. A circuit is woken up in response to receiving the indication if a control field of configuration information is in a first state, and the circuit is not woken up in response to receiving the indication if the control field of configuration information is in a second state.
摘要:
Circuits in a processor may provide an indication that power supplies are ready when waking from a reduced power state. The processor may include timers to measure a period of time, and may utilize voltage detectors to detect the voltages on the power supplies. A control register in the processor may influence the operation.
