In this document, the term Ô60xÕ is used to denote a 32-bit microprocessor from the PowerPC architecture family that conforms to the bus interface of the PowerPC 601ª, PowerPC 603ª, or PowerPC 604 microprocessors. Note that this does not include the PowerPC 602ª microprocessor which has a multiplexed address/data bus. 60x processors implement the PowerPC architecture as it is speciÞed for 32-bit addressing, which provides 32-bit effective (logical) addresses, integer data types of 8, 16, and 32 bits,and ßoating-point data types of 32 and 64 bits (single-precision and double-precision).1.1 Overview The MPC106 provides an integrated high-bandwidth, high-performance, TTL-compatible interface between a 60x processor, a secondary (L2) cache or additional (up to four total) 60x processors, the PCI bus,and main memory. This section provides a block diagram showing the major functional units of the 106 and describes brießy how those units interact.Figure 1 shows the major functional units within the 106. Note that this is a conceptual block diagram intended to show the basic features rather than an attempt to show how these features are physically implemented on the device.

Abstract: This reference design provides design ideas for a cost-effective, low-power liquid-level measurement dataacquisition system (DAS) using a compensated silicon pressure sensor and a high-precision delta-sigma ADC. Thisdocument discusses how to select the compensated silicon pressure sensor, suggest system algorithms, and providenoise analyses. It also describes calibration ideas to improve system performance while also reducing complexity andcost.

This application note describes the implementation of a two-dimensional Rank Order filter. Thereference design includes the RTL VHDL implementation of an efficient sorting algorithm. Thedesign is parameterizable for input/output precision, color standards, filter kernel size,maximum horizontal resolution, and implementation options. The rank to be selected can bemodified dynamically, and the actual horizontal resolution is picked up automatically from theinput synchronization signals. The design has a fully synchronous interface through the ce, clk,and rst ports.

The power of programmability gives industrial automation designers a highly efficient， cost-effective alternative to traditional motor control units （MCUs）。 The parallel-processing power， fast computational speeds， and connectivity versatility of Xilinx® FPGAs can accelerate the implementation of advanced motor control algorithms such as Field Oriented Control （FOC）。 Additionally， Xilinx devices lower costs with greater on-chip integration of system components and shorten latencies with high-performance digital signal processing （DSP） that can tackle compute-intensive functions such as PID Controller， Clark/Park transforms， and Space Vector PWM. The Xilinx Spartan®-6 FPGA Motor Control Development Kit gives designers an ideal starting point for evaluating time-saving， proven， motor-control reference designs. The kit also shortens the process of developing custom control capabilities， with integrated peripheral functions （Ethernet， PowerLink， and PCI® Express）， a motor-control FPGA mezzanine card （FMC） with built-in Texas Instruments motor drivers and high-precision Delta-Sigma modulators， and prototyping support for evaluating alternative front-end circuitry.

Abstract: Many modern industrial, medical, and commercial applications require temperature measurements in the extended temperature rangewith accuracies of ±0.3°C or better, performed with reasonable cost and often with low power consumption. This article explains how platinumresistance temperature detectors (PRTDs) can perform measurements over wide temperature ranges of -200°C to +850°C, with absolute accuracyand repeatability better than ±0.3°C, when used with modern processors capable of resolving nonlinear mathematical equation quickly and costeffectively. This article is the second installment of a series on PRTDs. For the first installment, please read application note 4875, "High-Accuracy Temperature Measurements Call for Platinum Resistance Temperature Detectors (PRTDs) and precision Delta-Sigma ADCs."

The Audio File Library provides a uniform programming interface to standard digital audio file formats. This library allows the processing of audio data to and from audio files of many common formats (currently AIFF, AIFF-C, WAVE, NeXT/Sun .snd/.au, IRCAM, AVR, Amiga IFF/8SVX, and NIST SPHERE). The library also supports compression (currently G.711 mu-law and A-law and IMA and MS ADPCM) as well as PCM formats of all flavors (signed and unsigned integer, single- and double-precision floating point).
