Section F:
In a CPU, a register in which intermediate results are stored. Without an accumulator, it would be
necessary to write the result of each calculation (addition, subtraction, shift, and so on.) to main
memory and read them back. Access to main memory is slower than access to the accumulator,
which usually has direct paths to and from the arithmetic and logic unit (ALU).
1. A logic signal having its asserted state as the logic 1 state.
2. A logic signal having the logic 1 state as the higher voltage of the two states.
1. A logic signal having its asserted state as the logic 0 state.
2. A logic signal having its logic 1 state as the lower voltage of the two states: inverted logic.
The label or number identifying the memory location (RAM, ROM, or register) where a unit of
information is stored.
A procedure for solving a mathematical problem in a finite number of steps that frequently
involve repetition of an operation.
The temperature of the air in a designated area, particularly the area surrounding the PSoC
device.
As opposed to digital, signals that are on or off or ‘1’ or ‘0’. Analog signals vary in a continuous
manner. See also analog signals .
The basic programmable opamp circuits. These are SC (switched capacitor) and CT (continuous
time) blocks. These blocks can be interconnected to provide ADCs, DACs, multi-pole filters, gain
stages, and much more.
An output that is capable of driving any voltage between the supply rails, instead of just a logic 1
or logic 0.
A signal represented in a continuous form with respect to continuous times, as contrasted with a
digital signal represented in a discrete (discontinuous) form in a sequence of time.
A device that changes an analog signal to a digital signal of corresponding magnitude. Typically,
an ADC converts a voltage to a digital number. The digital-to-analog (DAC) converter performs
the reverse operation.
