倚天710性能監(jiān)控—DDR PMU子系統(tǒng)
1. 倚天710的DDR5子系統(tǒng)
倚天710支持支持最先進(jìn)的DDR5 DRAM，為云計算和HPC提供巨大的內(nèi)存帶寬。倚天710有8 DDR5通道（channel），每個Die上有4個。每個通道相互獨(dú)立地服務(wù)系統(tǒng)的內(nèi)存請求，分別支持用于1DPC（DIMM Per Channel）的DDR5-4400和2DPC的DDR5-4000。
1.2 DDR5 Architecture
DDR5的一個主要變化是新的DIMM通道結(jié)構(gòu)（Fig 2中Channel Architecture）。DDR4 DIMM的總線位寬為72比特，由64比特數(shù)據(jù)位和8比特ECC位組成。DDR5的每個DIMM有兩個獨(dú)立的子通道。兩個通道中的總線位寬都為40比特：32比特的數(shù)據(jù)位和8比特的ECC位。盡管DDR4和DDR5的數(shù)據(jù)位寬相同（總共64比特），但兩個獨(dú)立通道可以提高內(nèi)存訪問效率并減少延遲。單通道單次任務(wù)只能讀或?qū)?，雙通道的DDR5則讀寫可以同時進(jìn)行。
1.2 DDR5 理論帶寬
倚天2DPC的DDR5-4000的理論帶寬為：
- 4000MHz *32bit / 8 *8 *2 = 128 *10^9 *2 bytes = 128GB/s *2= 256 GB/s
- 內(nèi)存等效頻率（4000MHz）_ 子通道位寬（32 bit）/ 8 _ 子通道數(shù)（8）* Die （2）
注意GB和GiB的不同：
- 1 GB = 1000000000 bytes (= 1000^3 B = 10^9 B)
- 1 GiB = 1073741824 bytes (= 1024^3 B = 2^30 B).
2. 倚天710 DDRSS PMU
倚天710的DDRSS為每個子通道都實(shí)現(xiàn)了獨(dú)立的PMU，用于性能和功能調(diào)試，每個子通道的PMU包含16個通用計數(shù)器。
帶寬計算公式為：
- DRAM Read Bandwidth = perf_hif_rd *DDRC_WIDTH *DDRC_Freq / DDRC_Cycle
- DRAM Write Bandwidth = (perf_hif_wr + perf_hif_rmw) *DDRC_WIDTH *DDRC_Freq / DDRC_Cycle
- DDRC_WIDTH: Units of 64 bytes
