Cache Memory Storage

Architecture Cache
Use of the Cache block as the L2 cache, receiving request from the I_1 and D_1 in the processor and a miss to a DRAM.
Cycle-Accurate Cache
Modeling the cycle-accurate cache with 4-way associativity and snoop flag disabled.
Cache/Memory Hierarchy
Shows an end-to-end operation with Processor core as a trace, 2 level cache, AXI bus, Memory Controller and DRAM
Architecture Memory
Use of the Cache block as the L2 cache, receiving request from the I_1 and D_1 in the processor and a miss to a DRAM.
Cycle-accurate Memory
Modeling multiple requester with addresses to DDR and LPDDR
Disk
Host computer with SATA interface to a local disk drive
Hybrid Drive
Multi-level drive with cache, SDRAM, flash and disk drive. Uses a ARM R8 for contorl processing
Flash
Evaluate flash from different memory vendors by varying standard Flash parameters
SSD
SSD using a generic Flash and a RISC-V for processing
Network-Attached Storage
Modeling a video streaming server that is stored on a redundant NAS

"This model makes requests to a moving disk with ""Read"" or ""Write"" commands in a field of the incoming data structure. Each request address associates a disk zone (A_Address_Min), disk sector (A_Address_Max) with fields of the DS. Commands alternate ""Read"", ""Write"". The zone and sector are randomized, so the head movement, latency is noticible.

The Disk has a Cache with a user settable threshold for accumulating transactions in the model. When this threshold is reached, then it begins to send transactions to the disk, looking for sequential reads and writes in shortening the head latency. There is a latency for the cache currently in the model, and assumes the cache is within the disk. There is provision for sequential read and write commands in the Traffic Generator. Zone is the classic zoning nomenclature, Sector is for purposes of segmenting the disk, there are Disk parameters that also mention sector, more related to disk tracks where a sector is typically 512 bytes. The Disk does not fragment incoming data structures, assumes they are fragmented and ready for the disk."
