LabVIEW 8.2.1 supports Windows Vista

Next: System on Chip Design

System on Chip Design A simple design for a video system SOC appears in Figure 6 . The Diamond Video Engine, like the other system components, attaches to the main system bus in this SOC design. A host System Control processor directs the SOC's operation and can run code from on-chip and off-chip memory.

One of Tensilica's Diamond HiFi 2 Audio Engine cores provides digital-audio decoding in this design. The Diamond HiFi 2 Audio Engine can run a wide range of ready-to-run digital-audio codecs. (In some designs, the Diamond HiFi 2 Audio Engine can also serve as the host processor.)

Both the Diamond Video Engine and the Diamond Audio Engine, which is currently in volume production inside of mobile-phone SOCs, illustrate how processors and ready-to-run firmware can form the core of a complex, high-performance, low-power IP block. Using the block-oriented approach to design illustrated in Figure 6 , development teams can rapidly assemble extremely complicated SOCs from complex, proven IP cores and then program these SOCs with application code to produce unique products for the market.

Backward compatibility with the legacy devices (IEEE 802.11b/g) The typical 802.11n network consists of legacy 802.11b/g enabled systems and new 802.11n enabled MIMO-OFDM systems. The channel access scheme used in both the systems is CSMA/CA which mandates the interoperability and backward compatibility across these standards.

Challenges: Based on the transmission from/to the MIMO-OFDM system, we can arrive at two challenges in achieving this goal.

4. Designers must weight the relative importance of property definition and resource assignments.

One caution to consider when choosing technologies for properties contained within the OCP specification is the form in which the spec describes the properties. For example, the OCP specification describes the following signal to have an unambiguous value during a request:
