    Abstract: Location cache memory architectures that only require 32 Kbits or less per frame to store erasure information with simple address mapping to the main MPE-FEC RAM for easy column-wise and row-wise access. Alternative architectures are designed to greatly reduce the size and logic complexity of the MPE-FEC erasure cache memory. Two architectures reduce the erasure cache size down to 32 Kbits and 28 Kbits, correspondingly, without introducing additional erasure locations, while another architecture further reduces the required memory size down to 16K, 8K, 4K, or 2K bits with a slight increase in the total erasure locations. All architectures group the data in MPE-FEC frame memory into blocks of 2M consecutive bytes and use one or a few bits to store the erasure status in each block, thereby, greatly reducing the required cache memory size.

    Abstract: Methods and apparatus for reducing precision of an input signal, by comparing a portion of the input signal to a preselected threshold value, and determining a selectable bias responsive to the comparison. By combining a portion of the input signal with the selectable bias, a reduced precision signal, having minimized or eliminated rounding error, is generated. The selectable bias corresponds to a predetermined characteristic of one of bias, an error signal, the input datum, the reduced precision datum, and a combination thereof.

    Abstract: A multi-chip antenna diversity architecture and method includes a first receiver chip that receives a first input signal from a first antenna. The first receiver chip includes a first tuner that amplifies the first input signal, a crystal operatively connected to a first crystal oscillator circuit, and a first crystal oscillator clock buffer that receives a clock signal from the first crystal oscillator circuit. A first demodulator demodulates the input signal received from the first tuner. A second receiver chip receives a second input signal from a second antenna. The second receiver chip includes a second crystal oscillator circuit, a second crystal oscillator clock buffer, a second tuner, and a second demodulator that receives diversity data from the first demodulator. The first crystal oscillator clock buffer drives the clock signal to the second crystal oscillator clock buffer, the second tuner, and the second demodulator of the second receiver chip.
