context_page_description: The Atari Falcon030, released in 1992, was the final personal computer product from Atari Corporation. A high-end model of the Atari ST line, the machine is based on a Motorola 68030 CPU and a Motorola 56000 digital signal processor, a feature which distinguishes it from most other microcomputers of the era. It includes a new VIDEL programmable graphics system which greatly improves graphics capabilities.
  Shortly after release, Atari bundled the MultiTOS operating system in addition to TOS. TOS remained in ROM, and MultiTOS was supplied on floppy disk and could be installed to boot from hard disk.
  The Falcon was discontinued in late 1993–a year after its introduction–as Atari restructured itself to focus completely on the release and support of the Atari Jaguar video game console. The Falcon was sold in relatively small numbers, chiefly to hobbyists.
context_section_description: The heart of the system is the 32-bit Motorola 68030 clocked at 16 MHz.  It runs at about 5.76 MIPS while displaying video modes with the fewest colors. Despite its 32-bit CPU, the Falcon does not have 32-bit architecture throughout its design, as it has a 16-bit data bus and a 24-bit address bus. This reduces the 68030's performance when not operating inside its tiny cache and limits the maximum system memory to ≈14 MB.
  The microprocessor is supported by a Motorola 56001 DSP clocked at 32 MHz and performing ca. 16 million instructions per second. Although it is oriented to sound processing (it is directly connected to the RAM and codec via an interconnection matrix), it is also capable of graphics processing (for example, calculation of fractals, deformations, 3D projections, and JPEG decompression). It can even, jointly with the 68030, play MP3 files in real time.
  Another innovation (for its time) is the VIDEL video controller. The possibilities offered by the graphics processor are limited only by its frequency (25/32 MHz core, adjustable to 50 MHz with a hardware accelerator) and the slowness of the RAM, as the graphics memory is shared with system memory which can degrade performance significantly when using high resolutions or video modes requiring many bit planes. The parameters are numerous; each timing of a video line (start, end, number of pixels, etc.) is adjustable, the image may be interlaced or not, and the vertical frequency can go down to 50 Hz interlaced to display on a television. The number of colors is also adjustable when VIDEL operates in bit plane mode. This mode is available for compatibility with the previous generation, but is quite complex to manage. There is also a true color 16-bit mode in which bits defining each pixel are grouped together to display 65,536 colors simultaneously, though CPU performance is degraded while displaying this mode.
  In addition, Atari adopted the IDE bus in addition to the SCSI bus for connecting hard drives and CD-ROM drives. This allows for less expensive disk and CD-ROM devices, as SCSI interfaced devices remained relatively expensive. However, the IDE connector is internal and requires case modification to connect two hard disks or a single CD-ROM. The other drawback is that this early IDE port uses only programmed I/O unlike a SCSI drive that can directly access the RAM (DMA).
