Enumeration Type Documentation

MemoryAllocation_ChannelsType

enum MemoryAllocation_ChannelsType

strong

The number of channels.

Enumerator
MEM_ACC_11
MEM_ACC_N1	for each memory at maximum one direct access and one indirect access
MEM_ACC_NN	for each memory at maximum n parallel direct accesses and one indirect access
MEM_ACC_P1N	for each memory at maximum n parallel direct accesses and n parallel indirect accesses
MEM_ACC_CS	only external memory access Datapath see only 1 memory port, while the bus manage parallel accesses

Definition at line 76 of file memory_allocation.hpp.

MemoryAllocation_Policy

enum MemoryAllocation_Policy

strong

The allocation memory polycy.

Enumerator
LSS
GSS	all local variables, static variables and strings are allocated on BRAMs
ALL_BRAM	all global variables, static variables and strings are allocated on BRAMs
NO_BRAM	all objects that need to be stored in memory are allocated on BRAMs
EXT_PIPELINED_BRAM	all objects that need to be stored in memory are allocated on an external memory
NONE	all objects that need to be stored in memory are allocated on an external pipelined memory
