Abstract: A real-time computational device includes a programmable real-time processor, a communications input port which is connected to the programmable real-time processor through a first broadside interface, and a communications output port which is connected to the programmable real-time processor through a second broadside interface. Both broadside interfaces enable 1024 bits of data to be transferred across each of the broadside interfaces in a single clock cycle of the programmable real-time processor.

Abstract: A computational system includes one or more processors. Each processor has multiple registers, as well attached memory to hold instructions. The processor is coupled to one or more broadside interfaces. A broadside interface allows the processor to load or store an entire widget state in a single clock cycle of the processor. The broadside interface also allows the processor to move and store 32 bytes of information into RAM in less than four to five clock cycles of the processor while the processor concurrently performs one or more mathematical operations on the information while the move and store operation is taking place.

Abstract: Scratch pad register banks are used as shared fast access storage between processors in a multi processor system. Instead of the usual one to one register mapping between the processors and the scratch pad register banks, an any to any mapping is implemented. The utilization of the scratch pad register banks is improved as the any to any mapping of the registers allow the storage of any processor register anywhere in the scratch pad register bank.

Abstract: In the L2 FIFO architecture incoming frames are stored in a multi bank FIFO to enable offloading the programmable real-time unit to do other tasks. The L2 FIFO buffers data coming from the L1 FIFO, reducing the polling time for received data. Status is always checked for errors before processing the data and updating the state variables. Implementing a state machine to perform some of the checks results in a PRU utilization that is not a function of the bytes that need to be processed.
