Description
Technical Field
The invention belongs to the field of system-level chip design, and particularly relates to integrated circuit computing equipment and a computing processing system.
Background
Currently, in an FPGA (Field Programmable Gate Array) design, a processor hard core or a processor soft core is usually embedded, that is, an ASIC (application specific Integrated Circuit) Circuit of a processor is embedded inside an FPGA chip, or a processor is implemented on a Programmable logic of an FPGA in a manner of an HDL (Hardware description language) program code.
However, FPGAs with embedded processor hardcores are commercial IP cores such as ARM (Advanced RISC Machine), PowerPC, etc., and the use of commercial IP greatly increases the use cost of the FPGA user, on one hand, the cost of the FPGA itself is increased, and on the other hand, when the user wants to convert the design on the FPGA into an ASIC (Application specific integrated Circuit) design, the user still needs to pay extra IP use cost; secondly, the internal design details of most commercial IP cores (internal Property cores) are invisible, which cannot meet the requirements of application scenes (such as security scenes of national defense and military industry) with the requirement that the chips are completely safe and controllable; third, commercial IPs have poor design flexibility and, once a certain IP is selected, subsequent product upgrades are limited by IP capabilities. The FPGA using the soft core needs to occupy logic resources on the FPGA when the soft core is implemented, and occupies a large power consumption, a large area, and a lower computing power compared with the hard core, so that the FPGA cannot meet application requirements of high precision and high real-time performance, and is relatively poor in practicability.

The first processing module is a system on chip using RISC-V instruction set for the core processor, which can be CPUBlock, and the inner part is integrated with RISC-V instruction set processor hard core. The second processing module is an FPGA Block. Of course, in other embodiments, the processor in the first processing module may also be a circuit such as a GPU, a DSP, or a hardware accelerator that employs a RISC-V architecture.
In one embodiment, the apparatus further comprises:
