ANSI escape code

In computing, ANSI escape codes (or escape sequences) are a method using in-band signaling to control the formatting, color, and other output options on video text terminals. To encode this formatting information, certain sequences of bytes are embedded into the text, which the terminal looks for and interprets as commands, not as character codes.

ANSI codes were introduced in the 1970s and became widespread in the minicomputer/mainframe market by the early 1980s. They were used by the nascent bulletin board system market to offer improved displays compared to earlier systems lacking cursor movement, leading to even more widespread use.

Although hardware text terminals have become increasingly rare in the 21st century, the relevance of the ANSI standard persists because most terminal emulators interpret at least some of the ANSI escape sequences in the output text. One notable exception is the win32 console component of Microsoft Windows.

History

Almost all manufacturers of video terminals added vendor-specific escape sequences to perform operations such as placing the cursor at arbitrary positions on the screen. One example is the VT52 terminal, which allowed the cursor to be placed at an x,y location on the screen by sending the ESC character, a y character, and then two characters representing with numerical values equal to the x,y location plus 32 (thus starting at the ASCII space character and avoiding the control characters).

Reality Coprocessor

Reality Coprocessor (RCP) is one of the Nintendo 64's two main chips, alongside the NEC VR4300, a derivative of the MIPS R4200. The RCP was developed by Silicon Graphics for Nintendo, specifically for the Nintendo 64 video game console.

The RCP consists of two main components: the Reality Signal Processor (RSP) and the Reality Display Processor (RDP).

Reality Signal Processor

The RSP is a vector processor designed for high performance 3D calculations. It handles some audio and most video pre-processing of the Nintendo 64. Its capabilities include real-time edge anti-aliasing, automatic load-management, texture mapping, and real-time depth buffering. The RSP has access to 4 KB of DMEM (Data Memory) and executes instructions contained within its 4 KB of IMEM (Instruction Memory), allowing 1024 instructions to be stored at any given time. These instructions are collectively referred to as microcode. Microcode may be designed to perform specific tasks such as lighting calculations or RDP display list processing. The RSP is able to transfer data to and from main memory and DMEM/IMEM using DMA.
