FPGA设计指南:器件、工具和流程.part1.rar少了。。。另外,感谢阿
已经重新上传 谢谢The OpenRISC 1200 is an implementation of OpenRISC 1000 processor family. The OR1200 is a 32-bit scalar RISC with Harvard microarchitecture, 5 stage integer pipeline, virtual memory support (MMU) and basic DSP capabilities. Default caches are 1-way direct-mapped 8KB data cache and 1-way direct-mapped 8KB instruction cache, each with 16-byte line size. Both caches are physically tagged. By default MMUs are implemented and they are constructed of 64-entry hash based 1-way direct-mapped data TLB and 64-entry hash based 1-way direct-mapped instruction TLB. Supplemental facilities include debug unit for real-time debugging, high resolution tick timer, programmable interrupt controller and power management support. General Microarchitecture - Central CPU/DSP block
- IEEE 754 compliant single precision FPU
- Direct mapped data cache
- Direct mapped instruction cache
- Data MMU based on hash-based DTLB
- Instruction MMU based on hash-based ITLB
- Power management unit and power management interface
- Tick timer
- Debug unit and development interface
- Interrupt controller and interrupt interface
- Instruction and Data WISHBONE B3 compliant interfaces
