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...
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.

;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 ...
It involves connecting the TCM to the regular data master and the tightly-coupled instruction master, since the TCIM can't write to memory. 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 every...
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,...
For example, it would happen when your instruction master spans addresses 0 to 0xfffffff and you place TCM base address to 0x10000000; in this configuration the processor decoder needs to test only bit 12 in order to decide if it must access to main bus or TCM. The aim is 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...
A typical case where this might be done would be a dual port memory with one port connected to a trellis coded modulation (TCM) instruction master and the other port connected to a TCM data master. This configration is not supported. Workaround: Do not place program memory ...
