Block Partitioning
(Ask a Question)Block partitioning aggregates consecutive elements of the original array into partitions.
The number of partitions (blocks) is defined by the factor argument.
#pragma HLS memory partition variable(array2d) type(block) dim(1) factor(2) int array2d[10][20];
For example, in the above code snippet array2d is specified to partition
dimension 1 with factor 2. The result is two
int[5][20] partitions where the first partitions has elements
0, 1, 2, 3, 4, and the second has elements 5, 6, 7, 8,
9 of dimension 1.
Important: If the number of
elements
N in the specified dimension is not divisible by
factor, all the partitions will have the same size B =
ceil(N/factor), except the last partition which will have the remaining
elements N - (factor - 1) * B. For example, if N = 10 and
factor = 3, the resulting partitions will have 4,
4 and 2 elements respectively.
