Abstract

Systems and methods are provided to enhance the functionality of an integrated circuit. Such an integrated circuit may include a primary circuitry and an embedded programmable logic programmable to adjust the functionality of the primary circuitry. Specifically, the embedded programmable logic may be programmed to adjust the functionality of the primary circuitry to complement and/or support the functionality of another integrated circuit. Accordingly, the embedded programmable logic may be programmed with functions such as data/address manipulation functions, configuration/testing functions, computational functions, or the like.

Claims (26)

1. An integrated circuit, comprising:

a first portion comprising base function circuitry of a system-on-chip (SoC), wherein the first portion operates using a first interface protocol; and

an embedded field programmable gate array configurable to perform protocol translation between the first interface protocol and a second interface protocol different than the first interface protocol.

2. The integrated circuit of claim 1 , wherein the second interface protocol comprises one or more standards.

3. The integrated circuit of claim 1 , wherein the first portion provides an advanced peripheral bus and the embedded field programmable gate array provides a receiver-transmitter interface.

4. The integrated circuit of claim 3 , wherein the embedded field programmable gate array comprises reconfigurable blocks to provide the receiver-transmitter interface.
