چکیده

One question commonly asked about software defined radios is “How much memory do I need?”. While the answer depends greatly on the software framework and underlying operating system, this paper describes tools used to measure memory usage on a Linux based system running the OSSIE SCA framework. In addition to the conventional tools commonly used to study memory usage, this paper introduces the exmap and exmap-console tools for performing detailed memory usage measurements. Results from these measurements help define how much memory a radio requires by accurately measuring memory usage. Accurate memory usage measurements allow the system designer to reduce the number of memory chips in the final hardware design, this leads to lower cost radios that require less power to operate.

Efficient Delay Characterization Method to Obtain the Output Waveform of Logic Gates Considering Glitches

Accurate delay calculation of circuit gates is very important in timing analysis of digital circuits. Waveform shapes on the input ports of logic gates should be considered, in the characterization phase of delay calculation, to obtain accurate gate delay values. Glitches and their temporal effect on circuit gate delays should be taken into account for this purpose. However, the explosive numbe...

STRS Compliant FPGA Waveform Development

The Space Telecommunications Radio System (STRS) Architecture Standard describes a standard for NASA space software defined radios (SDRs). It provides a common framework that can be used to develop and operate a space SDR in a reconfigurable and reprogrammable manner. One goal of the STRS Architecture is to promote waveform reuse among multiple software defined radios. Many space domain wavefor...

Distributed Disk-based Solution Techniques for Large Markov Models

Very large Markov chains often arise from stochastic models of complex real-life systems. In this paper we investigate disk-based techniques for solving such Markov chains on a distributed-memory parallel computer. We focus on two scalable numerical methods, namely the Jacobi and Conjugate Gradient Squared (CGS) algorithms. The critical bottleneck in these methods is the parallel sparse matrix-...
