16 Claims

1. A method of writing data to, and reading data from, one or more buffers, the method comprising:

determining a first write rate associated with writing data into a first buffer, wherein only updated parts of the first buffer are written to;

determining a first read rate associated with reading data from the first buffer;

determining a portion of the first buffer associated with the first write rate and the first read rate, wherein the portion of the first buffer is determined such that the reading of data from the first buffer does not overtake the writing of data into the first buffer;

writing data into the portion of the first buffer;

reading data from the first buffer responsive to completing the writing of data to the portion of the first buffer;

writing data into a remaining part of the first buffer, different from the portion of the first buffer; and

wherein determining the portion of the first buffer comprises determining a starting time for beginning to read the data from the first buffer such that t_r,0+(f(m)+1)TR/N≥t_w,m, where t_r,0is the time at which the zeroth row is read, f(m) is a function mapping each m-th updated row of M updated rows to a corresponding row in the first buffer, T_Ris the time required to read the entire first buffer, N is the number of rows of data in the first buffer to be read, and t_w,mis the time at which the m-th row is written to the first buffer.
