Difference between Loosely Coupled and Tightly Coupled …

WebA Nios II core can have zero, one, or multiple tightly-coupled memories. The Nios II architecture supports tightly-coupled memory for both instruction and data access. Each tightly-coupled memory port connects directly to exactly one memory with guaranteed low, fixed latency. The memory is external to the Nios II core and is located on chip. WebSome ARM SoCs have a so-called TCM (Tightly-Coupled Memory). This is usually just a few (4-64) KiB of RAM inside the ARM processor. Due to being embedded inside the CPU, the TCM has a Harvard-architecture, so there is an ITCM (instruction TCM) and a DTCM (data TCM). The DTCM can not contain any instructions, but the ITCM can actually …
