【摘要】 本论文分为两个部分:FPGA(Field Programmable Gate Array)硬件仿真平台的设计与实现,MIPS芯片组的设计与实现。由于硬件仿真能够大大提高仿真速度,并且由于其贴近实际情况,更容易发现设计中的缺陷。因此,硬件仿真在VLSI(Very Large Scale Integration)设计的功能验证中起着至关重要的作用。本文设计并实现了一个通用的FPGA硬件仿真平台。该仿真平台可以独立工作也可以与微机协同工作,具有较好的性能和较强的灵活性。芯片组(Chipset)作为计算机系统的中枢,负责管理CPU与其它外围设备之间的通讯。本文在对现有MIPS芯片进行研究的基础上,设计了一个与MIPS微处理器兼容的芯片组。该芯片组结构简单,易于实现,但又提供了足够的功能。除此之外,该系统结构易于扩展,可以添加不同的IP(Intellectual Property)模块来提供不同的功能。在设计的基础之上,我们完成了绝大多数模块的设计。论文的主要贡献表现在以下两个方面:设计并实现了一个通用的FPGA硬件模拟平台。设计并基本实现了MIPS微处理器兼容的芯片组。更多还原

【Abstract】 This thesis can be divided into 2 parts: design and development of a FPGA (Field Programmable Gate Array) emulation platform, design and implementation of a MIPS microprocessor compatible chipset.Compared with software simulation, Hardware emulation has much faster speed. Moreover, bugs are often easily found by emulation because it is closer to the real world. As a consequence, hardware emulation plays an important role in modern VLSI (Very Large Scale Integration) verification process. In this thesis, a universal FPGA emulation platform is designed, which can work independently or cooperatively with a computer. Besides this, this emulation platform has a satisfactory performance and flexibility.Chipset is the key element in a computer system, which connect the microprocessor and peripheral devices, such as SDRAM, PCI devices et al. In this thesis, a survey is given on MIPS microprocessor compatible chipset and a chipset architecture is brought forward. This architecture supports enough functions to MIPS microprocessor and is easy to implement. Moreover, this architecture is flexible to upgrade, various IP (Intellectual Property) cores can be added to provide different functions. Based on this architecture, all modules have been almost finished.This thesis makes contribution to the following two areas:Design and implement a universal FPGA emulation platform.Design and implement a MIPS microprocessor compatible chipset.更多还原
