The NaplesPU single core system is defined in the npu_system.sv module, under src/sc/system folder. The following figure depicts the organization of the NaplesPU Single Core version:
The single core version instantiates the following modules:
- NaplesPU core: module
npu_core(described in NaplesPU core architecture) - item interface:
npu_item_interfacemodule allows host-device communication and performance info fetching. - transaction logger:
npu_core_loggermodule logs both incoming responses from the main memory and issued requests from the core to the memory. This module stores up to CORE_LOG_SIZE (default 512) for the core issued transactions, and MEM_LOG_SIZE (default 512) - core interface:
core_interfacemodule connects the NaplesPU core and the cache-controller for the single core version, modulesc_cache_controller - cache controller:
sc_cache_controllermodule, the cache controller for the single core version of the NaplesPU architecture, described in Cache Controller - system bus:
mux_multimastermodule, shared multi-master bus. It allows both the core and the host-interface to concurrently access the main memory and custom devices - test device:
io_device_testmodule, an example of a memory mapped custom device in the NaplesPU system - synchronization core:
synchronization_coremodule, acts as the synchronization master allowing thread synchronization through barriers. The module is the same as the many core version, although it requires minor adjustments:
assign network_available = 1'b1; assign ni_account_mess_valid = c2n_account_valid;
Since the single core version of the system has no network, the network availability input port has to be constantly high.
