(中文) SystemC TLM2.0学习笔记

# TLM2.0的建模时间精度 TLM2.0支持两种不同的建模时间精度 粗略时间精度 适用于操作系统启动时间级别的评估以及多核架构评估 处理器运算可以超前于仿真时间 每次传输事务支持2个时间点:起始和结束 支持直接存储器接口(DMI) 精确时间精度 时钟周期级别的精度 适用于架构级别的评估 处理器运算与仿真时间完全同步 每次传输事务支持4个时间点:开始请求、结束请求、开始响应、结束响应 TLM2.0的接口类型 阻塞传输接口: void b_transport(TRANS& trans, sc_time& delay); 包括时间标记 通常用于粗略时间精度 仅提供正向传输 非阻塞传输接口: nb_transport_fw(TRANS&, PHASE&, sc_time&); nb_transport_bw(TRANS&, PHASE&, sc_time&); 包括时间标记和传输阶段 通常用于精确时间精度 包括正向和反向传输 直接存储器访问接口: get_direct_mem_ptr(TRANS& trans, tlm_dmi& dmi_data); invalidate_direct_mem_ptr(sc_dt::uint64 start_range, sc_dt:uint64 end_range); 调试传输接口 transport_dbg(TRANS& trans); 00

It has been about half a year since my last post. So many things happened during the time. Firstly, I have finished my first wechat game and submitted the soft copyright application request a few months ago. Hopefully I could get it approved by this winter. If so, I’d love to put it upon the […]

Today I told my wife about my new year revolution, that is, I will stick my actions to these rules for this year: I will not buy any new games before I really have finished one that I have bought. I will not take any more part-time jobs before my game is finished. I will […]
