A system and method to improve the transparency and security of an election are provided. In a first version, a tabulation system includes a paper ballot reader. The ballot reader informs a computational engine of the tabulation system in a digital data format of an informational pattern detected on each paper ballot. The computational engine processes the information provided by the ballot reader in accordance with a system software and in light of instruction and data inputs. The system software and a history of the tabulation system operations are provided as public rectory. The history may include the ballot reader output, computational activity of the tabulation system, computational results of the tabulation system, and instruction and data inputs.

Method and system for transparent and secure vote tabulation

Switched pull down (SPD) ECL circuits have a switching circuit within the pull down portion of the output stage, so that a large portion of the total pull down current is switched to the negative going output node, and so that a small portion of the total pull down current is switched to the positive going output node. The negative going output node has a larger that normal ECL pull down current attached to it. The larger pull down current on the negative going node discharges the output capacitor in a shorter period of time. The shorter discharge time of negative going output results in a shorter fall delay time. Two smaller current sources are connected to each of the two differential ECL outputs to insure that both pull up transistors are forward biased so as to provide an adequate noise margin and insure correct circuit operation. Forward biasing the pull up transistors with a minimum acceptable amount of bias current at the emitters of the output pull up transistors provides proper immunity to noise.

Switched pull down emitter coupled logic circuits

A specialized apparatus and method for providing fast programmed I/O for transferring information in a multi-processor environment which includes a CPU, and a memory coupled to an I/O port across an internal data bus. Multiple bytes of data are transferred in successive processing cycles to the I/O port from the memory, or from the I/O to the memory by first determining the upper limit for the number of bytes that are going to be transferred. This number and the memory start address are then stored in CPU registers. The I/O module is then checked by the CPU to see if a data byte is available from an external device. If a data byte is available, the I/O module is instructed to place the data byte on the bus for storage within the memory at the start address. The address is then incremented and the count is decremented. The above procedure is repeated until the count drops to zero, after which time the next instruction is fetched.

Apparatus and method for fast I/O data transfer in an intelligent cell

A computer architecture and method capable of retaining data after a system clock has been halted to conserve power. The computer comprises first processing circuitry, the first circuitry comprising dynamic components. The dynamic components include such devices as intermediate pipeline registers, arithmetic logic units, address generators, and instruction decode and control circuitry. The computer further comprises second processing circuitry, the second circuitry comprising static components. In a preferred embodiment, the static components comprise instruction registers, stop controls, general purpose registers, status registers, and random access memory. The use of dynamic components in the architecture of a preferred embodiment maximizes cost and size considerations, while the static components allows instruction execution and the system clock to be halted. The combination of dynamic and static components preserves information which enables the system to resume execution after the system clock has been stopped without data loss. This architecture reduces power consumption compared to a system implemented entirely in dynamic logic, while minimizing cost and area. Methods are also provided to stop this architecture and restart it without data loss.
