init_data |
void * |
pointer to the iniltialization data |
reconos_hwt_create
Description
Creates a new hardware thread running in the a specific slot. Before executed the slot will be resetted.
Parameters
| Name | Type | Description |
|---|---|---|
hwt |
struct reconos_hwt * |
pointer to the configuration structure |
slot |
int |
slot number to run the hardware thread in |
arg |
void * |
arguments for the delegate thread (passed to pthread_create) |
reconos_hwt_create_reconf
Description
Creates a new reconfigurable hardware thread running in the specific slot. Before executed the slot is reconfigured with the appropriate bitstream and resetted.
Parameters
| Name | Type | Description |
|---|---|---|
hwt |
struct reconos_hwt * |
pointer to the configuration structure |
slot |
int |
slot number to run the hardware thread in (same as in cfg) |
cfg |
struct reconos_configuration * |
pointer to the configuration |
arg |
void * |
arguments for the delegate thread (passed to pthread_create) |
reconos_configuration_init
Description
Initializes a new configuration with default values. This function must be called for every configuration you want to use.
Parameters
| Name | Type | Description |
|---|---|---|
cfg |
struct reconos_configuration * |
pointer to the configuration structure |
name |
char * |
name to identify the configuration |
slot |
int |
the slot number you want to run the configuration in |
reconos_configuration_setresources
Description
Associates a resource array to this configuration. This is the equivalent to reconos_set_resources for not reconfigurable hardware threads.
Parameters
| Name | Type | Description |
|---|---|---|
cfg |
struct reconos_configuration * |
pointer to the configuration structure |
resorce |
struct reconos_resource * |
pointer to the resource array to use |
resource_count |
size_t |
number of resources in the resource array |
reconos_configuration_setbitstream
Description
Associates a bitstream to this configuration to program the FPGA on reconfiguration.
Parameters
| Name | Type | Description |
|---|---|---|
cfg |
struct reconos_configuration * |
pointer to the configuration structure |
bitstream |
uint32_t * |
pointer to the bitstream data |
bitstream_length |
unsigned int |
length of the bitstream in 32bit-words |
reconos_configuration_loadbitstream
Description
Loads a bitstram from the filesystem and associates it to the configuration by calling reconos_configuration_setbitstream.
Parameters
| Name | Type | Description |
|---|---|---|
cfg |
struct reconos_configuration * |
pointer to the configuration structure |
filename |
char * |
filname of the bitstream-file |
