Portable Devices
Portable handheld-size devices can implement field test equipment, such as multimeters, handheld scopes, and automotive diagnostic devices.
These portable devices have been implemented using a host of discrete components and a CPU. It takes more time and resources to implement these custom hardware platforms, resulting in:
- Wasteful efforts developing standard blocks instead of custom application blocks
- Obsolescence risk from multiple discrete ASSP and CPU components
- Integration risk, cost, and inflexibility of ASICs
With the latest Quartus II development tools, SOPC Builder, Nios® II embedded processor, and programmable hardware capabilities of Altera’s CycloneTM II and Stratix® II FPGAs, you can:
- Integrate multiple ASSP devices and the CPU into a single application-independent FPGA
- Implement independent functions into multiple Nios II processors on a single FPGA
- Couple coprocessing logic with a Nios II processor to "supercharge" functional performance
- Easily integrate all the application-specific and standard intellectual property (IP) functionality with SOPC Builder
Additional productivity benefits include:
- Reusing previous engineering IP development efforts
- Leveraging additional Altera® MegaCore® and partner IP blocks
- Separating application-specific analog I/O and sensor circuits onto modular daughter cards
Figure 1 shows how a Cyclone or Stratix series FPGA implements a system-on-a-programmable-chip (SOPC) using one or more Nios II processors, including custom logic. The user interface, application-specific analog functionality, and network connectivity can be added to complete the portable device.
These implementation capabilities featured in Altera’s new portable reference platform and reference designs provide significant business benefits to equipment OEMs:
- Accelerating handheld device implementations and time-to-market for higher profitability
- Lowering the cost and power of devices via integrated functionality
- Leveraging application-independent devices across many applications (economy of scale)
- Providing both hardware and software flexibility for extended device utility and upgrades
