Abstract: A system and method for a common unified debug architecture for integrated circuits and System on Chips (SoCs) are provided. A system consistent with the present disclosure may comprise of an integrated circuit or SoC which includes a display port, plurality of logic blocks, and debug logic. The debug logic may receive debug data from one or more of the plurality of logic blocks in response to the integrated circuit or SoC operating in a debug mode. In addition, control logic coupled to the debug logic. The control logic provides display data to the display port in response to the integrated circuit operating in an operational mode. The control logic further directs high-speed debug data to the display port in response to the integrated circuit or SoC operating in the debug mode. The high-speed debug data is to be based on the debug data.

Abstract: Techniques of debugging a computing system are described herein. The techniques may include generating debug data at agents in the computing system. The techniques may include recording the debug data at a storage element, wherein the storage element is disposed in a non-core portion of the circuit interconnect accessible to the agents.

Abstract: In one embodiment, the present invention includes a system-on-a-chip (SoC) with first and second cores, interface logic coupled to the cores, chipset logic coupled to the interface logic, and a virtual firewall logic coupled between the chipset logic and the second core. The interface logic may include a firewall logic, a bus logic, and a test logic, and the chipset logic may include a memory controller to provide for communication with a memory coupled to the SoC. In some system implementations, both during test operations and functional operations, the second core can be disabled during normal operation to provide for a single core SoC, enabling greater flexibility of use of the SoC in many different implementations. Other embodiments are described and claimed.

Abstract: Methods and apparatus for output of high-bandwidth debug data/traces in electronic devices using embedded high-speed debug port(s). Debug data is received from multiple blocks and buffered in a buffer. The buffer's output is operatively coupled to one or more high-speed serial I/O interfaces via muxing logic during debug test operations. The buffered data is encoded as serialized data and sent over the one or more high-speed serial I/O interfaces to a logic device that receives serialized data and de-serializes it to generate parallel debug data that is provided to a debugger. The buffer may be configured as a bandwidth-adapting buffer that facilitates transfer of debug data that is received at a variable combined data rate outbound via the one or more high-speed serial I/O interfaces at a data rate corresponding to the bandwidth of the serial I/O interfaces.

Abstract: An interconnect bandwidth throttler is disclosed. The interconnect bandwidth throttler turns off the interconnect, based on whether a maximum number of transactions has taken place within a predetermined throttle window. Both the maximum number of transactions and the throttle window are adjustable. Characteristics such as performance, thermal considerations, and average power are adjustable using the interconnect bandwidth throttler.

Abstract: This invention describes a game of inverse chess, with a pre-identified start position, and end position and arbitered moves chosen amongst a set of possible moves, played between two opponents on a chess board. This differs from normal chess in that it is played backwards in time where the objective is to reconstruct the pre-identified start position, from the pre-identified end position. While the pieces used in the game are essentially the same as that of regular chess, the moves they make are reversed. Since the state-space of this game is much larger in the potential moves, an arbiter is used to validate possible moves that one player might choose to make. Using either a regular or modified chess board, the pieces on the board move backwards. Three such moves are described in the I-castle, spawn and I-check moves. A variant of the game is the two-knight game wherein two knights play each other and the piece reaching the pre-identified start position, win.
