Abstract: A packet transmission apparatus includes a processor such as a central processing unit (CPU), a first processing chip, and a second processing chip. The second processing chip is separately connected to the processor and the first processing chip. The second processing chip is disposed between the processor and the first processing chip. The first processing chip is a non-programmable chip such as an application-specific integrated circuit (ASIC) chip, and the second processing chip is a programmable chip such as a field-programmable gate array (FPGA) chip. The second processing chip supports a second function, and the second function is updatable. Both the processor and the first processing chip are configured to exchange a packet with the second processing chip. The second processing chip is configured to process a received packet based on the second function and send the processed packet to the processor or the first processing chip.

Abstract: A data processing method and apparatus, and a heterogeneous system, pertaining to the field of computer technologies are provided. The heterogeneous system includes a processor connected to an accelerator. A secondary memory is connected to the accelerator. The processor is configured to write to-be-processed data into the secondary memory and trigger the accelerator to access and process the to-be-processed data stored in the secondary memory according to a processing instruction. The accelerator is configured to write a processing result of the to-be-processed data into the secondary memory and to trigger the processor to read the processing result. Processing efficiency is enhanced by reducing the number of times of interaction between the processor and the accelerator and simplifying the procedure for data processing.

Abstract: A memory access method comprises adding routing information to a memory page table, so that a memory management unit (MMU) queries, in a process of performing address translation on a virtual address (VA), the memory page table to obtain the routing information. After querying the memory page table and obtaining a physical address (PA), the MMU may directly route the PA based on the routing information, whereby a system address decoder (SAD) is not needed for further decoding the PA.
