Code for TM320C54x (v2a.asm) download
This project involves the design and implementation of a audio synthesis device that converts moving images into audio signals. The system is built on a TM320C54x DSP with interface to an IMAQ camera module via the serial port on a PC. Brief description: A LabVIEW VI acquires an image from the IMAQ camera module. It quantizes the image into a 5x5, 3-bit image, and sends the data to the TM320C54x DSP via a serial port. The TM320C54x DSP constructs a 64-tap FIR by combining a series of 64-tap head related transfer functions (HRTF) according to the incoming data, and then filters an input audio signal with this FIR filter, in effect creating a correspondence between the filtered signal and the original image.
The concept of the Altera Nios II embedded processor implementation inside Field Programmable Gate Array [FPGA] of the CCD camera for the “Pi of the Sky” experiment is presented. The digital board of the CCD camera, its most important components, current implementation of firmware [VHDL] inside the FPGA and the role of external 8051 microcontroller is briefly described. The main goal of the presented work is to get rid of the external microcontroller and to design new system with Nios II processor built inside FPGA chip. Constraints for implementing the design into the existing camera boards are discussed. New possibilities offered by a larger FPGA for next generation of cameras are considered.

This design contains four top level circuits: sv_chip0.vhd, sv_chip1.vhd, sv_chip2.vhd and
sv_chip3.vhd each of them built by one Virtex2000E fpga chip. This design is hierarchical and the
sub-circuits can be used as smaller benchmarks.
The TW2835 has four high quality NTSC/PAL video decoders, dual color
display controllers and dual video encoders. The TW2835 contains four
built-in analog anti-aliasing filters, four 10bit Analog-to-Digital converters,
and proprietary digital gain/clamp controller, high quality Y/C separator to
reduce cross-noise and high performance free scaler. Four built-in motion,
This document contains a detailed description of the usage and configuration of the JSVM [Joint Scalable Video Model] software for the Scalable Video Coding [SVC] project of the Joint Video Team [JVT] of the ISO/IEC Moving Pictures Experts Group [MPEG] and the ITU-T Video Coding Experts Group [VCEG].
It provides information how to build the software on Windows32 and Linux platforms. It contains a description of the usage and configuration for the binaries built from the software package, including examples for spatial, SNR and combined scalability scenarios.
Guidelines for the integration and validation of new tools in the software are provided.
Abstract: This application note describes the program and data flash and how to erase/write the flash using the built-in utility
ROM. This application note applies to the MAXQ flash-based microcontrollers that use a sector erasable flash
The main MIPS processor of SMP8630 comes with a JTAG interface, allowing:
access to caches and data bus (DRAM) with a bandwidth of about 200kbit/s
examining the processor state whatever the execution mode (monice)
connecting to monice using mdi-server and using a gdb client on the processor to step and break
accurately whatever the execution mode
running semi-hosted applications
fl ash write tool

real-time traces: has not been built in CPU (Config3_TL=0) and only supported by MajicPLUS probes
(maybe built into emulator?)
S60 SDL is a Simple DirectMedia Layer adaptation for S60. SDL is a cross-platform multimedia library: Applications and libraries built on SDL can easily be ported to other operating systems. But S60 SDL does more than makes porting easy: S60 multimedia applications can be implemented without any knowledge of Symbian C++ native API and a developer can use SDL and standard C, C++ interfaces. The SDL development supports both Nokia OpenC and Symbian stdlib (ESTLIB) C implementations.
