Abstract: Various examples disclosed herein relate to deterministically controlling interconnect operations to provide dynamic power gating for a system. In an example, a microcontroller unit (MCU) is provided that includes a group of processing devices, a group of target resources, interconnect circuitry, and clock control circuitry. The interconnect circuitry connects the group of processing devices to the group of target resources. The clock control circuitry is coupled to the interconnect circuitry. The clock control circuitry is configured to identify an upcoming occurrence of a communication between a pair of devices comprised of one of the processing devices and one of the target resources, and prior to the occurrence of the communication, enable a clock associated with a path through the interconnect circuitry between the pair of devices.

Abstract: Various embodiments disclosed herein relate to compute offloading by supplying operands to hardware accelerators from central processing units. An example embodiment includes a system configured to perform compute offloading. The system comprises a processing unit configured to write data to a memory and a memory adaptor bridge coupled between the processing unit and the memory. The memory adaptor bridge is configured to, in response to an attempt by the processing unit to write an operand to a memory location mapped to a function of a hardware accelerator, write the operand to a different memory location accessible by the hardware accelerator. The memory adaptor bridge is further configured to obtain a result of the function performed on the operand by the hardware accelerator and provide the result of the function to a memory location accessible by the processing unit.

Abstract: A system for prefetching program code from flash memory that includes processing circuitry configured to execute program code and prefetch circuitry coupled to the processing circuitry. In an implementation, the prefetch circuitry is configured to analyze branch logic within the program code to identify a block of code to prefetch from flash memory. Once identified, the prefetch circuitry causes the block of code to be prefetched from flash memory and loaded to a memory buffer. In another implementation, the prefetch circuitry is further configured to receive a request to supply the processing circuitry with the block of code. Upon receiving the request, the prefetch circuitry determines that the block of code has already been fetched and loaded in the memory buffer. Once identified in the memory buffer, the prefetch circuitry causes the block of code to be supplied to the processing circuitry.

Abstract: Various examples disclosed herein relate to trimming of system elements to prepare the elements for execution of boot code and application code. In an example embodiment, a system is provided. The system includes memory access circuitry and processing circuitry coupled to the memory access circuitry. The memory access circuitry is configured to receive a read request corresponding to a set of instructions for execution by processing circuitry stored in non-volatile memory, determine whether to preempt current access to the non-volatile memory corresponding to one or more access requests in favor of the read request based on a priority of the read request relative to the one or more access requests, obtain the set of instructions from the non-volatile memory, and supply the set of instructions to the processing circuitry. The processing circuitry executes the set of instructions.
