(2) DMC Function operation
(a) Arbiter operation
(b) Memory manager operation
•
(c) Memory interface operation
(d) Low Power function
According to use, there are three kinds of built-in FIFOs.
DMC provide 2 kinds of Low Power modes.
1. read/write access arbitration
2. For read accesses, QoS (Quality of Service) is provided.
3. Hazard detection (Read after Read (RAR) and Write after Write (WAW)).
4. The arbiter keeps track of the activity of the bank of FSMs in the memory
1. Monitor and control DMC circuit
2. Issuing direct comand
3. Auto Refresh function is provided
1. command FIFO: 2 words
2. read data FIFO:10 words
3. write data FIFO:10 words
1. Set dmc_memc_cmd_3 register to realize Low_power (Self Refresh Mode).
2. Set dmc_memory_cfg_3 register, stop memory clock (DMCCLK) or as no memory
As the FIFO sizes of either read or write FIFO is 10 words.
For one transfer, the max size is 8 words.
access, CKE is set to invalid (CKE = low).
Note: For DMC , Read after Write and Write after Read are not provided.
interface. This enables the arbiter to select an entry from the queue that does
not stall the memory pipeline.
