Abstract: An analog TV receiver implementation on DSP allows mobile platforms to view analog TV broadcasting on LCD displays. The analog television receiver includes a demodulator for demodulating a received analog television signal, an analog to digital converter for digitizing the demodulated television signal and a digital signal processor for producing display signals from the digitized television signals. The digital signal processor being programmed to search for a horizontal synchronization signal in the television signal, track the horizontal synchronization signal and search for a vertical synchronization signal in the television signal. Next the processor separates a luminance and a pair of chrominance components of the television signal and demodulates the pair of chrominance components. Red, green and blue values are constructed from the demodulated chrominance components and the luminance components. Display signals are produced from the red, green and blue values.

Abstract: A method which determines by an optimizing compiler whether any variable in the given program equals to the given acyclic mathematical function f(x,y,...) applied to the given variables x, y, ... in the program. In one embodiment, the method includes expressing the bits of the value of the function f(x,y,..) as a Boolean function of the bits of the inputs x, y, ...; expressing, for every variable v and program statement s, the value taken by v when s is executed as a Boolean function V(s,v)(x, y, ...) of the bits of x, y, ...; and expressing, for every statement s, the condition under which the statement is executed as a Boolean function C(s)(x, y, ...) of the bits of the inputs x, y, .... Finally, a determination is made using a Boolean satisfiability oracle of whether, for the given variable v and program statement s, the following Boolean expression holds: C(s)(x,y,...) P> V(s,v)(x,y...)=f(x,y,...). In a second embodiment, the method includes expressing the value of f(x,y,...) as a plurality of functions f j (x,y,..) having the corresponding predicate P j (x,y,..); expressing, for every variable v and program statement s, the value taken by v when s is executed as a plurality of functions V j (s,v)(x,y,...), one for each predicate P j (x,y,..); and expressing, for every statement s, the condition under which the statement is executed as a plurality of functions C j (s)(x,y,...), one for each predicate P j (x,y,..). Finally, a determination is of whether for the given variable v and program statement s, V j (s,v)(x,y,...)=f j (x,y,..) whenever the predicate P j (x,y,..) and the condition C j (s)(x,y,...) are true.

Abstract: A method of parallelizing a pipeline includes stages operable on a sequence of work items. The method includes allocating an amount of work for each work item, assigning at least one stage to each work item, partitioning the at least one stage into at least one team, partitioning the at least one team into at least one gang, and assigning the at least one team and the at least one gang to at least one processor. Processors, gangs, and teams are juxtaposed near one another to minimize communication losses.

Abstract: A receiver includes a controller which receives A/D sampled input signals and shifts the sampled digital signal to compensate for Doppler effect in the input signal prior to demodulation. The controller compensates for a Doppler increased frequency by shifting the sampled digital signal so as to skip a sample period every n samples. This may be achieved by decreasing a cycle of m samples by one sample period every n samples. The controller compensates for a Doppler decreased frequency by shifting the sampled digital signal so as to add a sample period every n samples. This may be achieved by repeating a sample every n samples to shift the sampled digital signal. The compensation is performed in software on a multi-threaded processor.
