Abstract: A stream of data is accessed from a memory system using a stream of addresses generated in a first mode of operating a streaming engine in response to executing a first stream instruction. A block cache management operation is performed on a cache in the memory using a block of addresses generated in a second mode of operating the streaming engine in response to executing a second stream instruction.

Abstract: In some examples, a circuit includes an interface configured to couple to a memory that includes a set of outputs to provide a set of data from the memory. The circuit further includes a rotator coupled to the interface that includes a first set of multiplexors that each include a set of inputs coupled to the set of outputs of the interface and an output. The circuit further includes a storage circuit coupled to the rotator that includes a register file coupled to the outputs of the first set of multiplexors an alignment network. The alignment network includes a second set of multiplexors that each include a set of inputs coupled to the register file and an output.

Abstract: A streaming engine in a system receives a first set of stream parameters into a queue to define a first stream along with an indication of either a queue mode of operation or a speculative mode of operation for the first stream. Acquisition of the first stream then begins. At some point, a second set of stream parameters is received into the queue to define a second stream. When the queue mode of operation was specified for the first stream, the second set of parameters is queued and acquisition of the second stream is delayed until completion of acquisition of the first stream. When the speculative mode of operation was specified for the first stream, acquisition of the first stream is canceled upon receipt of the second set of stream parameters and acquisition of the second stream begins immediately.

Abstract: Software instructions are executed on a processor within a computer system to configure a steaming engine to operate in either a linear mode or a transpose mode. A stream of addresses is generated using an address generator, in which the stream of addresses includes consecutive nested loop iterations for at least a first loop and a second loop. While in the linear mode, the first loop is treated as an inner loop. While in the transpose mode, the second loop is treated as the inner loop. A matrix can be fetched from memory in the linear mode to provide row-wise vectors. A matrix can be fetched from the memory in the transpose mode to provide column wise vectors.

A matrix can be fetched from memory in the linear mode to provide row-wise vectors. A matrix can be fetched from the memory in the transpose mode to provide column wise vectors. Local storage on the streaming engine is organized as sectors based on the number of rows in the matrix to allow overlapping transposition processing and to minimize memory accesses.
