Embodiment Construction

[0025] specific implementation plan

[0026] The solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] The simulation target of the functional simulator of the reconfigurable special-purpose processor core provided in this embodiment is a reconfigurable special-purpose processor core, and its hardware architecture is as follows: figure 1 shown. The processor core is mainly composed of register bank, SRAM, main controller and reconfigurable controller. It adopts runtime dynamic reconfigurable technology and uses its internal reconfigurable unit to realize the space mapping from algorithm to computing engine. Improve overall processor flexibility and resource utilization. The reconfigurable special-purpose processor realizes the hardware acceleration of commonly used signal processing algorithms, such as FIR algorithm, correlation algorithm, FFT / IFFT, matrix operations, etc. Its coarse-grained reconfigurabl...

Abstract

The invention relates to a functional simulator for a reconfigurable dedicated processor core. The functional simulator comprises an external interface module, a control module and a calculation realization module, wherein the external interface module simulates functions of an internal register set and an internal SRAM of the reconfigurable dedicated processor core, receives a configuration instruction required to be simulated, analyzes obtained task information according to the configuration instruction, and writes the task information into a global task queue; the control module simulates a function of an internal main controller of the reconfigurable dedicated processor core, transmits the task information among modules according to the task queue, obtains a calculation task required to be executed currently and a calculation task that is about to be executed from the task queue, and calls the calculation realization module to execute the calculation tasks; and the calculation realization module executes a plurality of algorithms to output calculation result data and calculation states, and executes the transportation of the task information and the calculation result data. The functional simulator has the beneficial effects of higher simulation speed, convenience for system-level debugging and optimization, and favorability for improving the efficiency and reducing the cost.

Description

technical field [0001] The invention relates to a functional simulator of a reconfigurable special processor core, which is suitable for the software system development and design of the reconfigurable special processor core. technical background [0002] In traditional SoC system development, software design must wait until the entire hardware is completed, which makes the entire development cycle very long. In order to solve this problem, the software-hardware co-design method based on SystemC has become increasingly popular. But even so, once the simulation of the entire system (including operating system, driver, API and application program) is required, the SystemC-based simulator often consumes a long time, especially the cycle-accurate simulator. This greatly affects the progress of software development. [0003] is a widely used open source computer emulator and virtual machine software. It can simulate processors of various architectures and necessary subsystems,...
