Mini_core_tile MAS
1. Overview
Brief Description:
This document outlines the micro-architecture of the mini_core_tile module, which serves as a tile within a tile-based system. It manages data communication with neighboring tiles in multiple directions (North, East, West, South) and includes a local interface.
Purpose and Functionality:
The mini_core_tile module facilitates inter-tile communication and routing of data within a tile-based system. It supports UART communication, interfaces with neighboring tiles, and includes a local interface for communication with the mini core.

4. Functional Description
Operational Modes:
The mini_core_tile module operates in a single mode, facilitating data routing and communication with neighboring tiles.
Data Flow Description:
- The module receives clock (
clk) and reset (rst) signals for control. - It manages data communication in all four cardinal directions (North, East, West, South) with neighboring tiles using the specified input and output signals.
- Local requests are received and processed via the
in_local_req_valid,in_local_req, andin_local_readysignals. - It interfaces with the
routermodule for routing data between directions.
5. Configuration and Control
Configuration Registers:
The mini_core_tile module does not include explicit configuration registers. Configuration and control may be implemented at a higher system level.
