Abstract:
A system to manage out-of-order traffic in an interconnect network has initiators that provide requests through the interconnect network to memory resource targets and provide responses back through the interconnect network. The system includes components upstream the interconnect network to perform response re-ordering, which include memory to store responses from the interconnect network and a memory map controller to store the responses on a set of logical circular buffers. Each logical circular buffer corresponds to an initiator. The memory map controller computes an offset address for each buffer and stores an offset address of a given request received on a request path. The controller computes an absolute write memory address where responses are written in the memory, the response corresponding to the given request based on the given request offset address. The memory map controller also performs an order-controlled parallel read of the logical circular buffers and routes the data read from the memory to the corresponding initiator.
Abstract:
Current tasks being executed in a set of modules of a signal processing system managed via an interface block are aborted so as to permit the execution of new tasks by pipelining eliminating transactions of said current tasks and executing transactions of the new tasks. Upon arrival of a signal to abort the current tasks, data and/or memory accesses present in said interface block are discarded.
Abstract:
A microcontroller includes an input pin and internal pull-up and pull-down circuits. External pull-up and pull-down circuits are also coupled to the input pin. The microcontroller is operable according to different configuration modes which include configuring the input pin in a floating state. A control logic then configures the internal pull-up and pull-down circuits according to an internal pull-up mode to acquire a first input voltage signal (at a first logic value) from the input pin, and further configure the internal pull-up and pull-down circuits according to an internal pull-down mode to acquire a second input voltage signal (at a second logic value) from the input pin. A selection of the operating mode of the MCU is then made based on the acquired first and second logic values.

Abstract:
In accordance with an embodiment, a system includes an oscillator equipped circuit having an oscillator control circuit configured to be coupled to an external oscillator and a processing unit comprising a clock controller. The clock controller includes an interface circuit configured to exchange handshake signals with the oscillator control circuit, a security circuit configured to receive the external oscillator clock signal and configured to select the external oscillator clock signal as the system clock, and a detection block configured to detect a failure in the external oscillator clock signal. Upon detection of the failure, a different clock signal is selected as the system clock and the interface circuit to interrupts a propagation of the external oscillator.
Abstract:
A digital processor, such as, e.g., a divider in a PID controller, performs a mathematical operation such as division (or multiplication) involving operands represented by strings of bit signals and an operator to produce an operation result. The processor is configured by identifying first and second power-of-two approximating values of the operator as the nearest lower and nearest higher power-of-two values to the operator. The operation is performed on the input operands by means of the first and second power-of-two approximating values of the operator by shifting the bit signals in the operands by using the first and second power-of-two approximating values in an alternated sequence to produce: first approximate results by using the first power-of-two approximating value, second approximate results by using the second power-of-two approximating value. The average of the first and second approximate results is representative of the accurate result of the operation.
