An important advantage of the half-bridge (and all other double-ended topologies) is that the effective duty cycle as seen by the input and output filter is twice that of the individual switch duty cycles. The effective frequency is also twice that of the individual switch frequencies. The max effective duty cycle can approach 100% during low input voltage conditions. This important advantage allows for a small transformer as well as smaller input and output filtering.

ASIC manufacturers that cater to low-to-medium volume applications with medium-logic density requirements have developed a class of custom logic device called a structured ASIC. Targeted at mid-range ASIC applications that require better logic density, lower part price, and reduced power consumption than an FPGA can provide but without the high-volume requirements of a standard-cell ASIC, structured ASICs offer advanced CMOS technologies at low to moderate volumes combined with affordable design-cycle costs and low part prices.

John Lofton Holt: Well, it is the equivalent rate at which we process data through the architecture. So a clocked FPGA with a circuit laid out in the same way as on an Achronix prototype would have to operate at 1.93-GHz to get the same processing done in the same time that the Achronix prototype FPGA does it.

When properly tuned, the circuit in figure 7 is capable of smooth, rapid adjustment to RPM set point changes. It will zero in” on a desired speed quickly, without oscillation, and maintain the actual speed within fractions of a percentage point of the desired speed. This is referred to as a critically damped control loop [Figure 8]. Assuming the electrical and/or software aspects have been correctly implemented, the fan control loop response depends entirely on adjusting gain multipliers for the proportional, differential and integral terms.

AES HW and device key management Optional components deliver advanced encryption standards and support digital rights management (DRM), allowing for protection of content.

Set partitioning and encoding The key to TCM encoding is the set partitioning (Fig. 2) . The convolutional encoder's output of the—k of the payload bits becoming n output bits (n is greater than k) for a rate k/n encoder—selects one of the set partition'ssubsets in the TCM mapper. There are 2n subsets. The remaining bits delivered to the TCM mapper choose a point within the subset selected by the other two bits. In the example, one symbol is sent the convolutional encoder, which is basically a delay and multiply operation that outputs two coded symbols. This dependent, coded pairing is sent to the mapper. The two bits pick a sub-constellation from the subsets which have been methodically broken down into bipolar pairs. The final bit chooses one of the signal space points of the two within the chosen subset.

Also new in Quartus 6.0 is support for the SystemVerilog language. At present, said Fasan, Altera supports design implementation constructs in the IEEE 1800-2005 SystemVerilog standard, and it is examining which verification features to support in future releases.

For example, effective system-level board design requires good termination of some specific pins, idling some peripherals, and taking advantage of idle and power-down modes on the DSP. This can be achieved by dynamically turning off all peripherals and internal functional units when they are not in use. Minimizing power consumption will also help reduce cost, heat and component density.
