Systems and methods for efficient data buffering

One or more computer-readable non-transitory storage media embodying software that is operable when executed to:

• store a first position tracker associated with a first window of memory blocks in a memory unit, the first window being associated with a first data writing process of a first processing unit;
• allow the first processing unit to write within the first window;
• receive, from a second processing unit, a read request for reading data stored at a memory-reading address;
• compare the memory-reading address to a first starting address of the first window;
• prevent the second processing unit from reading the data based on a determination that the memory-reading address is greater than or equal to the first starting address of the first window;
• store, based on a determination that the first data writing process is complete, an updated first position tracker associated with a second window of memory blocks in the memory unit;
• and
• allow the second processing unit to read the data based on a determination that the memory-reading address is less than a second starting address of the second window, wherein the second processing unit reads the data at a second speed faster than the first speed, and wherein the second processing unit is turned off in response to a determination that more than a threshold time period is needed for the second processing unit to wait for the first processing unit to complete a second data writing process associated with the second window of memory blocks.

A system comprising:

• one or more non-transitory computer-readable storage media embodying instructions;
• and one or more processors coupled to the storage media and operable to execute the instructions to:
• store a first position tracker associated with a first window of memory blocks in a memory unit, the first window being associated with a first data writing process of a first processing unit;
• allow the first processing unit to write within the first window;
• receive, from a second processing unit, a read request for reading data stored at a memory-reading address;
• compare the memory-reading address to a first starting address of the first window;
• prevent the second processing unit from reading the data based on a determination that the memory-reading address is greater than or equal to the first starting address of the first window;
• store, based on a determination that the first data writing process is complete, an updated first position tracker associated with a second window of memory blocks in the memory unit;
• and
• allow the second processing unit to read the data based on a determination that the memory-reading address is less than a second starting address of the second window, wherein the second processing unit reads the data at a second speed faster than the first speed, and wherein the second processing unit is turned off in response to a determination that more than a threshold time period is needed for the second processing unit to wait for the first processing unit to complete a second data writing process associated with the second window of memory blocks.
