Privateeye Is an Image Viewer for RISC OS
Welcome PrivateEye is an image viewer for RISC OS. It requires RISC OS 3.6 or later and a Boot sequence with the Nested Wimp and a 32-bit Shared C Library. Features • Loads and displays bitmap and vector images • Sprites, JPEGs, GIFs and PNGs • DrawFiles and ArtWorks • Bitmap effects • Adjust gamma, brightness and contrast • Blur and sharpen • Change saturation and apply histogram effects • Alpha channel support • Bitmap rotation with interactive preview • Rotation is lossless for JPEGs • Native JPEG display using SpriteExtend • Inbuilt lossless “cleaning” transparently loads progressive JPEGs • JFIF, Exif and Adobe metadata information display • Multiple-channel histogram PrivateEye • Display images may be saved • Convert JPEGs, GIFs and PNGs to into Sprites Image Viewer • Any number of images may be open concurrently by David Thomas, © 1999–2017 • Customisable key map version 3.00 (08 Feb 2017) • Lots of interactive help (use it!) Supported Image Formats PrivateEye converts images as necessary into a JPEGs RISC OS-native format. This means that GIFs, PNGs and (optionally) JPEGs are converted into Sprite format when RISC OS’s SpriteExtend module, version 0.99 or later, is used they are loaded. to directly display JPEGs. This allows images larger than available free memory to be displayed by decompressing The converted image is referred to as the display image. and plotting on the fly. Operations such as saving, rotation and the effects system operate on the display image only. Progressive (multiple scan) JPEGs are supported. PrivateEye has an inbuilt version of jpegtran which automatically Sprites converts JPEGs into a baseline format that SpriteExtend can render. -

Ian PC 600 Burley gets a slice of the action. and CPU fans as the chip generates less than 1W of heat. Current ARM610s are 0.8 micron parts, and sample 0.6 micron parts are testing at 40MHz. One of the most striking aspects of the new RISC PC is its case, designed under the auspices of Allen Boothroyd, who designed the original BBC Micro and was a force behind hi-fi manufacturer Meridian. It is made of tough Bayer Bayblend ABS/Polycarbonate, which is used to make riot shields. Internal surfaces are coated to reduce radio frequency interference (RFI) but the external surface is an unpainted light grey. There is provision for screw-mounted peripherals inside but devices like CD-ROMs and hard disks will be clip-mounted Apple-style. Two twist-locking pins need to be turned 90° to get the case lid off. These can be padlocked and the case tethered. It takes less than a minute to open the case, swap processor modules and refit the lid, without any tools.

ARM Command Line Workbook
ARM Command Line Workbook CS160 Computer Organization Version 1.1 October 27th, 2002 Revised Fall 2005 ARM University Program Version 1.0 January 14, 1997 ARM Command Line Workbook Introduction Aim This workbook provides the student with a basic understanding of the facilities provided by the ARM Toolkit for command line users. Note: For all of the command line tools provided with the toolkit it is possible to get on- line help on the command line parameters by specifying the toolname followed by -help. Prerequisites Before getting started, you will need to add the ARM tools to your command path. Make the following change to the ~/.zsh_files/.zshrc file: • export PATH="$PATH:/pkgs/arm202u/bin" Next, you will need to add an environment variable so that the ARM compiler knows where to find the appropriate libraries. Make the following change to the ~/.zshrc file: • export ARMLIB="/pkgs/arm202u/lib" Ask the GTAs for help if you don’t know how to do this. When done, issue the commands: source ~/.zshrc ~cs160/bin/armsetup.pl The latter will create a hierarchy of subdirectories and files in a directory called arm within your cs160 directory. The reference /cmdline/hello.c thus should be read as ~/arm/cmdline/hello.c Compiler The ‘Hello World’ example program is a simple C program which calls a subroutine. This program file can be found as /cmdline/hello.c #include <stdio.h> /* Declare subroutine before used by main */ void subroutine (void); int main() { printf("Hello World from main\n"); subroutine(); printf("And Goodbye from main\n"); return 0; } /* Define subroutine */ void subroutine() { printf("Hello from subroutine\n"); } 2 ARM Command Line Workbook Exercise 1.1 Compile this program with the ARM C compiler type armcc -g hello.c The C compiler automatically invokes the linker to produce an executable with the same name as the C module but with no file extension. -
Updated Virtualrpc Components for RISC OS 6
ne of the main things that keeps me using my Risc PC is the versatility of the operating system - mainly due to it’s universal draw file format. For Oinstance I construct the centre pages in Artworks as this now has excellent PDF export facilities. However for proofing the magazine before it gets sent to the printers I like to do a printout to see if everything works properly. Because Artworks now can deal with multiple pages it is very easy to save each page either as an Artworks file or Draw file directly into the magazine’s Ovation Pro file by dragging and dropping. A two second job! Other computer platforms don’t generally have this facility of moving files directly into open application windows. Generally to move a file to another application you have to use the dreaded ‘save as’ filer window - choose a suitable format - navigate to where you need to save the file - save it - go to the other application - open a filer window - navigate to the saved file - open it in the new application. If you need to transfer a different file type you generally have to go through all that palaver again. Two seconds on RISC OS, thirty seconds on OS X or Windows. Draw is a great program with no real equivalent on a PC or Mac. For instance it can be put to good use in music for constructing objects the original program can’t do. I use the Sibelius music setting program on both RISC OS and Windows. The RISC OS still has one or two advantages over the PC version, one of which is it’s ability to export to Draw. -

A given ISA may be implemented with different microarchitectures.[1] Implementations might vary due to different goals of a given design or due to shifts in technology.[2] Computer architecture is the combination of microarchitecture and instruction set design. Relation to instruction set architecture The ISA is roughly the same as the programming model of a processor as seen by an assembly language programmer or compiler writer. The ISA includes the execution model, processor registers, address and data formats among other things. The Intel Core microarchitecture microarchitecture includes the constituent parts of the processor and how these interconnect and interoperate to implement the ISA. The microarchitecture of a machine is usually represented as (more or less detailed) diagrams that describe the interconnections of the various microarchitectural elements of the machine, which may be everything from single gates and registers, to complete arithmetic logic units (ALU)s and even larger elements. -
Chapter 13 ARM Image Format
Chapter 13 ARM Image Format This chapter describes the ARM Image Format (AIF). It contains the following sections: • Overview of the ARM Image Format on page 13-2 • AIF variants on page 13-3 • The layout of AIF on page 13-4. ARM DUI 0041C Copyright © 1997 and 1998 ARM Limited. All rights reserved. 13-1 ARM Image Format 13.1 Overview of the ARM Image Format ARM Image Format (AIF) is a simple format for ARM executable images, consisting of: • a 128-byte header • the image code • the image initialized static data. An AIF image is capable of self-relocation if it is created with the appropriate linker options. The image can be loaded anywhere and it will execute where it is loaded. After an AIF image has been relocated, it can create its own zero-initialized area. Finally, the image is entered at the unique entry point. 13-2 Copyright © 1997 and 1998 ARM Limited. All rights reserved. ARM DUI 0041C ARM Image Format 13.2 AIF variants There are three variants of AIF: Executable AIF Executable AIF can be loaded at its load address and entered at the same point (at the first word of the AIF header). It prepares itself for execution by relocating itself if required and setting to zero its own zero-initialized data. The header is part of the image itself. Code in the header ensures that the image is properly prepared for execution before being entered at its entry address. The fourth word of an executable AIF header is: BL entrypoint The most significant byte of this word (in the target byte order) is 0xeb. -
