TMS320C672x is a floating point device family from Texas Instruments that provides high quality audio performance at low prices. The price/performance ratio makes C672x well suited for numerous audio applications. This application note shows how to use C672x to efficiently create delay-based audio effects. The application note explains: • How to leverage the data movement accelerator (dMAX) to ...

We propose a restructuring of U. S. Federal debt. All debt should be perpetual, paying coupons forever with no principal. The debt should be composed of the following: 1) Fixedvalue, floating-rate, electronically transferable debt. Such debt looks like a money-market fund, or reserves at the Fed, to an investor. 2) Nominal perpetuities. This debt pays a coupon of $1 per bond, forever. 3) Indexe...

The best known method for determining lower bounds on the vertex coloring number of a graph is the linear-programming column-generation technique first employed by Mehrotra and Trick in 1996. We present an implementation of the method that provides numerically safe results, independent of the floating-point accuracy of linearprogramming software. Our work includes an improved branch-and-bound a...

In an attempt to manage the risk of mismatch between the actual claims and the anticipated claim amounts in motor insurance pool, we introduce a few new concepts of motor loss ratelinked securities such as motor loss rate options and motor loss rate swaps. These hybrid derivatives can transfer the motor insurance loss rate risks to the capital markets. For the valuation of the motor loss rate-l...

A system for the rapid prototyping of floating point hardware designs is presented. This system, called Float, consists of a floating point class for the simulation of quantization effects associated with low precision floating point operators; an optimizer which can automatically determine the minimal number of exponent and fraction bits required for a specified degree of accuracy; and a param...

We consider the performance of the delta hedging strategy obtained from a local volatility model when using as input the physical prices instead of the model price process. This hedging strategy is called robust if it yields a superhedge as soon as the local volatility model overestimates the market volatility. We show that robustness holds for a standard Black–Scholes model whenever we hedge a...

l Modular architecture separated execution units with distributed microcode. Large memory up to 7 Mbytes of separated program and data memory configurable in l/2 Mbyte units. FORTRAN 77 fully supported, with the exception of I/O instructions, including double precision 64 bit floating point thus giving results identical bit for bit to an IBM CPU. Conservative design of execution units maximum c...

This paper is a quantitatively-oriented theoretical study into the interaction between housing prices, aggregate production, and household behaviour over a lifetime. We develop an overlapping generations model of a production economy in which land and capital are combined into residential and commercial structures. We …nd that, in the economy where land is more important for structures, the hou...

In the literature, the study of price subsidies of new technologies has focused on the tactical problem of achieving maximum penetration under a budget constraint over a short horizon. In practice, such tactical, short-termpenetration objectives seemboth to adequately reflect the structure ofmany price subsidy programs (e.g., solar energy), and account for their high failure rate. The present p...

It is suggested that instead of attempting to adjust the consumer price index (CPI) after tax reform it is better to measure changes in after-tax income.
