Like the 68HC11, the 68HC12 has two 8-bit accumulators A and B (referred to as a single 16-bit accumulator, D, when A & B are cascaded so as to allow for operations involving 16 bits), two 16-bit registers X and Y, a 16-bit program counter, a 16-bit stack pointer and an 8-bit Condition Code Register.
When code generation occurs at runtime, as in just-in-time compilation (JIT), it is important that the entire process be efficient with respect to space and time. For example, when regular expressions are interpreted and used to generate code at runtime, a non-deterministic finite-state machine is often generated instead of a deterministic one, because usually the former can be created more ...
In 1988, researchers began investigating how to use regions for safe memory allocation by introducing the concept of region inference, where the creation and deallocation of regions, as well as the assignment of individual static allocation expressions to particular regions, is inserted by the compiler at compile-time. The compiler is able to ...
A long double (eight bytes with Visual C++, sixteen bytes with GCC) will be 8-byte aligned with Visual C++ and 16-byte aligned with GCC. Any pointer (eight bytes) will be 8-byte aligned. Some data types are dependent on the implementation. Here is a structure with members of various types, totaling 8 bytes before compilation:
Enough to uniquely identify one codon of genetic code. The size of code points in Base64; thus, often the entropy per character in a randomly-generated password. 7 bits – the size of code points in the ASCII character set – minimum length to store 2 decimal digits. 2 3: byte (B) 8 bits – (a.k.a. octet or octad(e)) on many computer ...
The Intel 8080 ("eighty-eighty") is the second 8-bit microprocessor designed and manufactured by Intel.It first appeared in April 1974 and is an extended and enhanced variant of the earlier 8008 design, although without binary compatibility. [3]
A POWER8 processor is a 6- or 12-chiplet design with variants of either 4, 6, 8, 10 or 12 activated chiplets, in which one chiplet consists of one processing core, 512 KB of SRAM L2 cache on a 64-byte wide bus (which is twice as wide as on its predecessor [1]), and 8 MB of L3 eDRAM cache per chiplet shareable among all chiplets.

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.
