WebRegisters are created when the value stored by a variable must be maintained over one or more clock cycle. Arrays of a fixed size or variables must be used in place of any dynamic memory allocation." It also says: "Memory allocation system calls must be removed from the design code before synthesis." So in short malloc is not supported. WebAn HLS compiler has to optimize the memory hierarchy of a hardware implementation and parallelize its data paths [5]. In order to achieve good Quality of Results (QoR), HLS languages demand programmers also to specify the hardware architecture of an application instead of just its algorithm. For this reason, HLS languages offer hardware ... philtrum purpose in humans

WebFrom what I know of HLS and Vivado, I expect that HLS will include the array in its synthesis output - but Vivado will remove it during synthesis as long as it's really not connected to anything. If the array is accessible from outside the block then that counts as being used, so it'll be kept by both tools.
