Abstract: A method includes receiving a first request to allocate a line in an N-way set associative cache and, in response to a cache coherence state of a way indicating that a cache line stored in the way is invalid, allocating the way for the first request. The method also includes, in response to no ways in the set having a cache coherence state indicating that the cache line stored in the way is invalid, randomly selecting one of the ways in the set. The method also includes, in response to a cache coherence state of the selected way indicating that another request is not pending for the selected way, allocating the selected way for the first request.

Abstract: The present disclosure provides methods and apparatuses for interrupt processing. An interrupt processing method includes executing a first interrupt by using a common register, receiving a second interrupt and a second priority of the second interrupt during execution of the first interrupt, comparing a first priority of the first interrupt with the second priority of the second interrupt, generating a first register index corresponding to the second priority of the second interrupt by using a look-up table based on the second priority of the second interrupt being greater than the first priority, and, based on the first register index being a dedicated index, maintaining a context of the first interrupt stored in the common register, assigning a dedicated register for execution of the second interrupt, and executing an interrupt program corresponding to the second interrupt by using the assigned dedicated register. The interrupt program is saved in a memory.

Abstract: A digital data processor includes an instruction memory storing instructions specifying data processing operations and a data operand field, an instruction decoder coupled to the instruction memory for recalling instructions from the instruction memory and determining the operation and the data operand, and an operational unit coupled to a data register file and an instruction decoder to perform an operation upon an operand corresponding to an instruction decoded by the instruction decoder and storing results of the operation. The operational unit is configured to perform a table recall in response to a look up table read instruction by recalling data elements from a specified location and adjacent location to the specified location, in a specified number of at least one table and storing the recalled data elements in successive slots in a destination register. Recalled data elements include at least one interpolated data element in the adjacent location.

Abstract: An apparatus includes a central processing unit (CPU) core and a cache subsystem coupled to the CPU core. The cache subsystem includes a first memory, a second memory, and a controller coupled to the first and second memories. The controller is configured to receive a transaction from a master, the transaction directed to the first memory and comprising an address; re-calculate an error correcting code (ECC) for a line of data in the second memory associated with the address; determine that a non-correctable error is present in the line of data in the second memory based on a comparison of the re-calculated ECC and a stored ECC for the line of data; and in response to the determination that a non-correctable error is present in the line of data in the second memory, terminate the transaction without accessing the first memory.
