  • Page 72: Theory Of Operation

    CPU Theory of Operation: Theory of Operation Theory of Operation Clocks The main system logic operates from one of three clocks, all derived from a single 24MHz oscillator. That 24MHz clock is used directly by the FPGA to control the timing of internal peripherals. It is also used as the reference frequency for the LCD controller PLL clock synthesizer (after division to 12MHz) and the PLL clock synthesizer in the StrongARM (after division to 4MHz).

  • Page 73: Bootstrap Instruction Unpacker

    CPU Theory of Operation: Theory of Operation Bootstrap Instruction Unpacker The FPGA provides an interface that unpacks instructions to start the CPU from the byte wide SmartMedia card. Early during system startup, Curly extracts instruction bytes from the card and presents them to the FPGA for unpacking.

    CPU Theory of Operation: Theory of Operation Video Waveform Scrolling There are numerous ways of achieving this effect, none of which is supported by standard LCD controllers. MAC 5000 achieves scrolling through FPGA hardware placed between the LCD controller output and the LCD panel input.

  • Page 75: Interrupt Controller

    CPU Theory of Operation: Theory of Operation Interrupt Controller The StrongARM supports two external interrupts, FIQ (Fast Interrupt Request) and IRQ (Interrupt ReQuest). The FPGA expands these inputs to service numerous sources of interrupts in the FPGA internal logic and SuperIO.

    CPU Theory of Operation: Theory of Operation transceiver and a 3-way bi-directional multiplexer to attach to the three BBus microcontrollers. From the programmer’s standpoint, BBus operates like SPI, where each transaction exchanges a single byte between the host and peripheral. UARTS Two full duplex UARTs are provided for COM3 and COM4.

  • Page 78: Dram

    CPU Theory of Operation: Theory of Operation DRAM Program code and working data is stored in a single 1MWord bank of 32-bit wide memory (4MBytes). EDO DRAM is used to achieve moderate burst rates (75MBytes/sec @ 26MHz bus speed). All bus timing and refresh control is performed by the FPGA.

    CPU Theory of Operation: Theory of Operation 650 ohms. Presuming negligible driver leakage current, a single enabled dot would drop 3.9V. While there are mitigating influences (off-pixel driver leakage current and on-pixel driver saturation voltage) that might make accurate pixel resistance measurements difficult, it is certainly possible to differentiate pixels of nominal resistance from those that are blown open.

  • Page 80: Startup Self Identification

    CPU Theory of Operation: Theory of Operation Although there are four of these little fellows in the MAC 5000, each performing a different function, there is only one firmware image. By merging the code from each of the four functions into a single ROM image confusion is reduced.

  • Page 81: Larry

    CPU Theory of Operation: Theory of Operation Larry Larry controls the paper drive motor and quantizes the analog inputs. Since Larry’s code is not field alterable, every motor control parameter is alterable via BBus. Hopefully this renders the code immune to minor changes in the printer drive train.

Battery Pack The MAC 5000 uses a 15-cell nickel metal hydride (NiMH) battery pack with integral thermal sensor for charge termination detection and self resetting fuse for short circuit protection.

    CPU Theory of Operation: Theory of Operation peak currents (drawn during printing) are clipped to the current monitor’s full scale value. The effects of this are minimal as such high density printing occurs for short periods of time and represents only a small portion of system energy consumption.

    CPU Theory of Operation: Theory of Operation Untested "Nominal" These specifications are affected by battery pack characteristics. While they are of interest, it is not possible to test them in production. These Operating Time Specs are "nominal specs" and are only guaranteed for a new battery pack of 3.5A capacity.
