This paper describes space-time resource tradeoff experiments carried out on the dynamically reconfigurable “Plastic Cell Architecture (PCA)” with cryptographic and evolutionary computation kernels. Data-path-oriented processing functionality is encapsulated in asynchronous hardware objects with variable graining and implemented using look-up tables.(More)
This paper describes a dynamically reconfigurable hardware-based computer called the Plastic Cell Architecture (PCA). PCA consists of dualstructured sea-of -cells that consist of a built-in part and a plastic part. The built-in part forms ‘cellular automata’ while the plastic part looks like an SRAM-based FPGA. We detail the design flow especially how to(More)
We propose a new general-purpose computer architecture based on programmable logic. It consists of a dual-structured array of cells accommodating a fixed “built-in part” and a freely programmable “plastic part”. We call this composition the “Plastic Cell Architecture” (PCA). The built-in part with its fully connective two-dimensional mesh structure serves(More)
This paper introduces a new concurrent processing model called "Communicating Logic" (CL). As the target architecture we adopt the dual layered "Plastic Cell Architecture" (PCA). Data-path-oriented processing functionality is encapsulated in asynchronous hardware objects with variable graining and implemented using look-up tables. Communication (i.e.(More)
