Effective January 1st 2022, ICE Enterprises will increase all product prices by 20%. Market forces, both rising component cost and increasing material lead time, are requiring the first price adjustment in company history. This price increase will allow ICE Enterprises to continue to design and manufacture quality electronic hardware as has been the case for over two decades. ICE Enterprises will honor all current price quotes and accept orders at existing pricing through the end of December 2021.
ICE in Brief
- Product: Low Cost, High Performance, Digital Signal Processing
- Approach: Software Reconfigurable Hardware
- Ported X-Midas to Linux PC for low-cost system-in-a-box and LapTop applications (1994).
- Developed Java-based MIDAS technology for the Web. NeXtMidas = Networked XMidas.
- Java environment for graphics, portability, rhobustness, and industry interface (JavaBeans).
- Java primitives support local host or browser based processing and/or real-time GUIs.
- Native code (C/C++/Fortran) processing primitives support local host or DSP nodes.
- Extended Midas macro language for application and GUI development at the engineering level.
- Two-tier application model. Remote Midas InterFace with network bandwidth reduction hooks, embedded WebServer.
- Goal is to provide framework allowing Midas engineers to program hardware.
- Open source model - runs on Unix, Windows, or VMS.
- Developed ICE-PIC, high-speed PCI data acquisition / playback (1996)
- Dual channel modular I/O.
- High-level programmable DSP.
- Run-time programmable Gate Array.
- Special purpose digital tuner chips.
- Multi-site modular Processing. (2002)
- Flexible data-flow and module interconnects.
- Drivers for Linux, OpenVMS, Digital Unix, Solaris, SGI, Windows-9X/NT, MacG3.
- Growing line of products - keeping in step with current technologies.
- DSPs - general purpose, good at FFTs, data movement, sequencing, terrible with bits. Easy to program.
- TigerSharc TS201 = 3.6GFlop, 14.4GOp, 5Gby/sec IO, 2.5Watts.
- FPGA - good at bits, serial correlation, data packing, terrible at floating point.
- Fixed point 16x16 multiply takes 100nS, 600 cells. Typical size 2-5000 cells. E321 algorithm in 1000 cells = one Alpha 4100.
- DIGITAL TUNERS - great for tuning, filtering. Low power. No programming.
- Graychip GC4016 = 4 chan, 100MHz, 18GOp.
- PLATFORM FPGA - Field Programmable Gate Arrays with RISC core, dedicated FP multipliers and 3GIO.
- With 44 MAC units at 250MHz = 22GOp. 3.2Gby/s full duplex serial IO bandwidth.
- At 2Watts per chip, it is possible to bring 22GOp to a Laptop, or 220GOp to a PCI slot. (Xilinx Virtex-2 Pro or Altera Stratix)
Fixed Point vs Floating Point
- Floating point is easy to code, fixed point must handle scaling issues.
- Fixed point (usually 16bit) typically requires only 1/2 the IO bandwidth.
- Fixed point performance/power: 10GOp/W (PFPGA), 2GOp/W (TI6414).
- Floating point performance/power: 1GFlop/W (TMS), 0.5GFlop/W (TigerSharc), 0.2GFlop/W (Pentium).
- Telecommunications algorithms are usually fixed point code for portability/power reasons.
- Max processing in a PCI slot: 200GOp Fixed (PFPGA), 4GFlop Float (TMS).
- Max processing in a LapTop slot: 20GOp Fixed, 0.6GFlop Float (SHARC/PPC).
- There will always be more data to process than we have resources for. Maximize processing density.
The Near Future
- Extreme fixed/floating-point processing, running standard software primitives.
- 200GOp processing in PCI slot, 20GOp in Laptop.
- 10 Gbit/sec I/O architecture, with capture to disk.
- Hanging hardware off the network with RMIF (ICEBOX, ICE-NIC).
