An 8-bit register can store 2 8 different values. The range of integer values that can be stored in 8 bits depends on the integer representation used. With the two most common representations, the range is 0 through 255 (2 8 − 1) for representation as an binary number, and −128 (−1 × 2 7) through 127 (2 7 − 1) for representation as two's complement.
The first computer to have multiple parallel discrete single-bit ALU circuits was the 1951 Whirlwind I, which employed sixteen such "math units" to enable it to operate on 16-bit words. In 1967, Fairchild introduced the first ALU-like device implemented as an integrated circuit, the Fairchild 3800, consisting of an eight-bit arithmetic unit ...
An arithmetic logic unit (ALU) capable of adding and subtracting 8-bit 2's complement integers from registers A and B. This module also has a flags register with two possible flags (Z and C). Z stands for "zero," and is activated if the ALU outputs zero. C stands for "carry," and is activated if the ALU produces a carry-out bit.
The Intel 8008 ("eight-thousand-eight" or "eighty-oh-eight") is an early 8-bit microprocessor capable of addressing 16 KB of memory, introduced in April 1972. The 8008 architecture was designed by Computer Terminal Corporation (CTC) and was implemented and manufactured by Intel.
A full adder can be viewed as a 3:2 lossy compressor: it sums three one-bit inputs and returns the result as a single two-bit number; that is, it maps 8 input values to 4 output values. (the term "compressor" instead of "counter" was introduced in [ 13 ] )Thus, for example, a binary input of 101 results in an output of 1 + 0 + 1 = 10 (decimal ...
8-bit to 9-bit bus transceiver with parity register, non-inverting three-state 24 SN74ABT833: 74x834 1 8-bit to 9-bit bus transceiver with parity register, inverting three-state 24 IDT74FCT834: 74x835 1 8-bit shift register with 2:1 input multiplexers, one input latched, serial output 24 74F835: 74x839 1 field-programmable logic array 14x32x6
68HC11 block diagram. Internally, the HC11 instruction set is backward compatible with the 6800 and features the addition of a Y index register. [a] It has two eight-bit accumulators, A and B, two sixteen-bit index registers, X and Y, a condition code register, a 16-bit stack pointer, and a program counter. In addition, there is an 8 x 8-bit ...
A binary multiplier is an electronic circuit used in digital electronics, such as a computer, to multiply two binary numbers.. A variety of computer arithmetic techniques can be used to implement a digital multiplier.
