Reconfigurable system-on-chip and related methods

摘要

A circuit includes combinational circuit and sequential circuit elements coupled thereto. The circuit includes a multiplexor coupled to the combinational and sequential circuit elements, and a system register is coupled to the multiplexor. At least one portion of the combinational and sequential circuit elements is configured to selectively switch to operate as a random access memory.

1. A method of operating a reconfigurable digital circuit comprising combinational and sequential circuit elements, the method comprising:
selectively switching at least one portion of the sequential circuit elements to operate as random access memory within an address space; remapping the address space to receive a virtual random access memory (VRAM) input when the at least one portion of the sequential circuit elements is switched to operate as the random access memory; receiving the VRAM input at a VRAM combinational logic circuit; and transmitting the VRAM input from the VRAM combinational logic circuit to the sequential circuit elements.
