Abstract(in English) | SLM (Scalable Logic Module) is a fine-grained reconfigurable logic developed by Kumamoto University, characterized by its small configuration information size, which results in a smaller area for logic cells. We are currently developing a new FPGA that incorporates SLM, CPU, switches, and memory. This chip leverages the small configuration information of SLM to store multiple configuration data in internal memory and switch them rapidly. In this paper, we propose a method to compress configuration information, allowing us to store even more configuration data. This compression method can be quickly expanded within the chip and can be implemented with simple hardware. Additionally, the configuration information of the target SLM reconfigurable logic often exhibits recurring patterns within internal modules. Therefore, we propose DMC (Duplicated Module Compression) as a compression method that aligns with these conditions. DMC registers recurring patterns in a dictionary to perform run-length compression. Regarding the expansion circuit, logic synthesis for the NANGATE45nm process was conducted using Synopsys' Design Compiler N-2017.09-SP1. As a result, the expansion circuit, on its own, was found to operate at 1GHz with a small circuit area of 708.9μm2 when a delay was set. |
