Abstract

The invention discloses a circuit board based on SOPC (System on a programmable chip) analog brain waves and a method for constructing a brain dynamic model. The circuit board comprises an FPGA (Field Programmable Gate Array) chip, a configuration chip, a clock source, an SDRAM (Synchronous Dynamic Random Access Memory), a FLASH, a display screen, a JTAG (Joint Test Action Group) debugging and downloading interface and buttons. The method comprises the steps as follows: creating a project, naming the project, and creating an SOPC system; establishing a top module of the system; establishing a new project and a corresponding BSP project; compiling a program and arranging a compiler. Through the circuit board and the method, transformation between a single nerve cluster model and a three nerve cluster coupled model, parameter adjustment and static display of a display screen can be realized by the buttons, and brain waves similar normal brain waves and brain waves in epileptic attack are generated and statically displayed by the display screen, thereby providing a foundation for further study on the brain dynamic model, the brain mechanism and hardware controlled by the brain dynamic model.

Description

technical field [0001] The present invention belongs to the intersecting field of digital integrated circuits and neurodynamics, and mainly develops and builds a brain power model based on a System on a programmable chip (SOPC) circuit board to generate brain waves similar to normal and epileptic seizures. In particular, it relates to a circuit board for simulating brain waves based on SOPC and a method for constructing a brain dynamics model. Background technique [0002] With the development of chip manufacturing technology, SOPC technology, that is, programmable system on chip, has become a development direction of embedded system design. It is a more flexible and efficient SOC solution. The second generation of customer-configurable The general-purpose 32-bit RISC soft-core processor, that is, the NIOS II embedded processor system, is currently the more popular SOPC. It is an IP core of FPGA. It is debugged through JTAG. Its biggest feature is that it is a soft core and...
