Directional two-dimensional router and interconnection network for field programmable gate arrays, and other circuits and applications of the router and network

A configurable directional 2D router for Networks on Chips (NOCs) is disclosed. The router, which may be bufferless, is designed for implementation in programmable logic in FPGAs, and achieves theoretical lower bounds on FPGA resource consumption for various applications. The router employs an FPGA router switch design that consumes only one 6-LUT or 8-input ALM logic cell per router per bit of router link width. A NOC comprising a plurality of routers may be configured as a directional 2D torus, or in diverse ways, network sizes and topologies, data widths, routing functions, performance-energy tradeoffs, and other options. System on chip designs may employ a plurality of NOCs with different configuration parameters to customize the system to the application or workload characteristics. A great diversity of NOC client cores, for communication amongst various external interfaces and devices, and on-chip interfaces and resources, may be coupled to a router in order to efficiently communicate with other NOC client cores. The router and NOC enable feasible FPGA implementation of large integrated systems on chips, interconnecting hundreds of client cores over high bandwidth links, including compute and accelerator cores, industry standard IP cores, DRAM / HBM / HMC channels, PCI Express channels, and 10G / 25G / 40G / 100G / 400G networks.

Flexible matrix fabric design framework for multiple requestors and targets in system-on-chip designs

The System-on-Chip (SOC) interconnection apparatus and system discloses an internal switching fabric that interconnects, via standard connection ports, one or more requestors and one or more addressable targets on a single semiconductor integrated circuit. Each target has a unique address space, may or may not have internal arbitration, and may be resident (i.e., on-chip) memory, a memory controller for resident or off-chip memory, an addressable bridge to a device, system, or subsystem, or any combination thereof. Targets and requesters are connected to the internal switching fabric using target and requestor connection ports. The internal switching fabric routes signals between requesters and targets using one or more decoder / router elements that determine which target is the designated target using an internal system memory map. Dedicated arbiters may be included for targets without internal arbitration.

Method of physical planning voltage islands for ASICs and system-on-chip designs

Voltage islands enable a core-level power optimization of ASIC / SoC designs by utilizing a unique supply voltage for each cluster of the design. Creating voltage islands in a chip design for optimizing the overall power consumption consists of generating voltage island partitions, assigning voltage levels and floorplanning. The generation of voltage island partitions and the voltage level assignment are performed simultaneously in a floorplanning context due to the physical constraints involved. This leads to a floorplanning formulation that differs from the conventional floorplanning for ASIC designs. Such a formulation of a physically aware voltage island partitioning and method for performing simultaneous voltage island partitioning, level assignment and floorplanning are described, as are the definition and the solution of floorplanning for voltage island based designs executed under area, power, timing and physical constraints. The physical planning of voltage islands includes: a) characterizing cell clusters in terms of voltages and power consumption values; b) providing a set of cell clusters that belong to a single voltage island Random Logic Macro (RLM); and c) assigning voltages for the voltage island RLMs, all within the context of generating a physically realizable floorplan for the design.

Sequential clock gating using net activity and xor technique on semiconductor designs including already gated pipeline design

The circuit design process requires ways to reduce the power consumption of large integrated circuits and system-on-chip designs. This is typically done by introducing a process of clock gating thereby enabling or disabling flip-flops associated with specific functional blocks within the circuit. However, such changes in the circuit require synthesis and verification to ensure correctness of design and operation as sequential clock gating changes the state function dynamically. It is therefore necessary to define synthesis methods adapted to such dynamic changes in the design. According to an embodiment a sequential clock gating method uses an exclusive-OR technique to overcome the deficiencies of the prior art methods.
