TCM(Tightly Coupled Memory)紧耦合存储器前身 参考paper《Scratchpad Memory : A Design Alternative for Cache On-chip memory in Embedded Systems》 在本文中,我们通过提出暂存器存储器作为缓存的替代方案,解决了计算密集型应用的片上存储器选择问题。使用CACTI工具计算不同暂存器和缓存大小的面积和能量,同时使用模拟...
;CONSTITUTION: method accesses TCM (210) with memory (TCM) request for being stored in close-coupled. The TCM transmits processing or memory to TCM managers (220). Handling information includes precedence information. Memory includes the memory of address access, access frequency and last access ...

By enabling the processor’s tightly-coupled memory host, Nios II processor gains guaranteed fixed low-latency access to on-chip memory for performance critical applications.
When I ran a program out of TCM I had two, an instruction and data memory. In the IDE I assigned .text to the instruction memory and everything else to the data memory. I don't know anything about custom linking scripts but I know I've seen examples on the forum so a...
Before using tightly coupled memory I had just one 8k normal onchip memory for the bootloader and the irq stuff of the main application was in sdram. This setup worked without any problems. With the tightly coupled memories I could successfully start the bootloader in the 6k tcm from the ...
The embodiment of the invention discloses a method for implementing code replacement by a TCM (tightly coupled memory). The method comprises the following steps of loading a first code to an instruction tightly coupled memory (ITCM); configuring the address of the ITCM as a first code address,...
I found that warning output whenever I put tightly coupled memory at low addresses. Trying to decode the error message led be to believe (IIRC) that the script was trying to find the low-high bounds of all the tightly coupled memory areas, but has a signed v unsigned compare error...
Not sure I understand all of this, but it sounds best to not use tightly coupled data memory unless I have a very specific need for it. --- Quote End --- I guess you missed the point. What dsl meant is that if you move code to TCM you might still have a few accesses to ...
Where I can find the tcm.zip example, mentioned in "Using Tightly Coupled Memory with the Nios II Processor" ? Actually, I can load my ISR function to the tightly_coupled_instruction_memory. But the tightly_coupled_data_memory seems to be unused. Til now, i haven't any perfor...
