Turbo equalization also flowed from the concept of turbo coding. In addition to turbo codes, Berrou also invented recursive systematic convolutional (RSC) codes, which are used in the example implementation of turbo codes described in the patent. Turbo codes that use RSC codes seem to perform better than turbo codes that do not use RSC codes.
With the release of Turbo C++ 1.0 (in 1990), the two products were folded into one and the name "Turbo C" was discontinued. The C++ compiler was developed under contract by a company in San Diego, and was one of the first "true" compilers for C++ (until then, it was common to use pre-compilers that generated C code, ref. Cfront).
Turbo coding is an iterated soft-decoding scheme that combines two or more relatively simple convolutional codes and an interleaver to produce a block code that can perform to within a fraction of a decibel of the Shannon limit. Predating LDPC codes in terms of practical application, they now provide similar performance.
The ability to more precisely manage the connections of the various constituent codes and the level of redundancy for each input bit give more flexibility in the design of LDPC codes, which can lead to better performance than turbo codes in some instances. Turbo codes still seem to perform better than LDPCs at low code rates, or at least the ...
Turbo Assembler (sometimes shortened to the name of the executable, TASM) is an assembler for software development published by Borland in 1989. It runs on and produces code for 16- or 32-bit x86 MS-DOS and compatibles for Microsoft Windows .
When investigating the possibility of removing friend name injection from the C++ programming language, Barton and Nackman's idiom was found to be the only reasonable use of that language rule. Eventually, the rules for argument-dependent lookup were adjusted [ 2 ] to replace friend name injection by a less drastic mechanism, described above ...
Turbo C++ 3.0 was released on November 20, 1991, amidst expectations of the coming release of Turbo C++ for Microsoft Windows. Initially released as an MS-DOS compiler, 3.0 supported C++ templates , Borland's inline assembler and generation of MS-DOS mode executables for both 8086 real mode and 286 protected mode (as well as 80186 ). 3.0 ...
For example, \11 is an octal escape sequence denoting a byte with decimal value 9 (11 in octal). However, \1111 is the octal escape sequence \111 followed by the digit 1 . In order to denote the byte with numerical value 1, followed by the digit 1 , one could use "\1""1" , since C concatenates adjacent string literals.
