ATLANTiS Framework
Embedded signal processing applications increasingly require flexibility, adaptability, and reprogrammability. The ability to modify a system in the real world is crucial for many systems. When this is coupled with the requirements of floating-point signal processing - low latency, high throughput, extended precision and dynamic range - the ability to properly satisfy all requirements using one processing technology diminishes. A design that includes both FPGAs and DSPs - a hybrid architecture - provides the best solution. But FPGAs are not processors, and therefore do not have an internal architecture, an instruction set, data paths, or a peripheral set. FPGAs, by definition, simply provide the raw materials and components that allow – and require – a user to create everything from scratch. If a user must create their own DMA/Memory interface or host/control interface for the FPGA in addition to proprietary algorithmic development, this defeats the basic purpose of COTS – to reduce development costs, risks, and time-to-deployment.
To successfully include FPGAs as part of the signal processing chain, board architectures must also include an FPGA framework: ATLANTiS. ATLANTiS provides fully validated board-level interfaces for I/O, communications, and memory; an internal dataflow interconnect fabric that allows the ATLANTiS modules to be easily connected; and a control fabric that allows them to be easily coordinated and controlled. This framework creates a stable, high performance signal processing platform that frees the designer to focus on application development rather than reinventing board-level infrastructure.
ATLANTiS Features
- Supports low-level board interfacing
- Allows the user to focus on proprietary algorithm development
- Supports dynamic connections between any on-board and off-board I/Os
- Communications can be point-to-point or broadcast to various outputs
- Provides communication between the TigerSHARC link ports and all other I/Os connected to the FPGA/board
- Off-board I/O is defined by board architecture
- Devices' connections can be reconfigured as requirements dictate without recompiling or changing cables
- Standard and custom developed IP blocks are available
ATLANTiS Overview
BittWare's ATLANTiS framework is an I/O switching and processing device implemented in the on-board FPGA. ATLANTiS facilitates off-board I/O and provides communications routing and processing, allowing system designers to setup and dynamically change connections as their specific applications require. All inputs and outputs are routed through ATLANTiS, supporting a throughput of greater than 5 GB/sec per DSP cluster. By tightly integrating DSPs, PCI bridge, PMC interface, and I/O peripherals with the on-board FPGA, ATLANTiS gives designers nearly infinite options for configuring and routing the I/O, greatly increasing the performance and flexibility of multi-processor, multi-board applications.
