Abstract
The present invention, generally speaking, provides a reconfigurable computing solution that offers the flexibility of software development and the performance of dedicated hardware solutions. A reconfigurable processor chip includes a standard processor, blocks of reconfigurable logic (1101, 1103), and interfaces (319a, 319b, 311) between these elements. The chip allows application code to be recompiled into a combination of software and reloadable hardware blocks using corresponding software tools. A mixture of arithmetic cells and logic cells allows for higher effective utilization of silicon than a standard interconnect. More efficient use of configuration stack memory results, since different sections of converted code require different portions of ALU functions and bus interconnect. Many types of interfaces with the embedded processor are provided, allowing for fast interface between standard processor code and configurable 'hard-wired' functions.
