- The Group Decode ROM: The 8086 processor’s first step of instruction decoding (righto.com)
A key component of any processor is instruction decoding: analyzing a numeric opcode and figuring out what actions need to be taken. The Intel 8086 processor (1978) has a complex instruction set, making instruction decoding a challenge. The first step in decoding an 8086 instruction is something called the Group Decode ROM, which categorizes instructions into about 35 types that control how the instruction is decoded and executed. For instance, the Group Decode ROM determines if an instruction is executed in hardware or in microcode. It also indicates how the instruction is structured: if the instruction has a bit specifying a byte or word operation, if the instruction has a byte that specifies the addressing mode, and so forth.
- Vincent van Gogh (Wikipedia)
Vincent Willem van Gogh (Dutch: [ˈvɪnsɛnt ˈʋɪləɱ vɑŋ ˈɣɔx]; 30 March 1853 – 29 July 1890) was a Dutch Post-Impressionist painter who is among the most famous and influential figures in the history of Western art. In just over a decade, he created approximately 2,100 artworks, including around 860 oil paintings, most of them in the last two years of his life. His oeuvre includes landscapes, still lifes, portraits, and self-portraits, most of which are characterised by bold colours and dramatic brushwork that contributed to the rise of expressionism in modern art. Van Gogh’s work was only beginning to gain critical attention before his death from suicide at age 37. During his lifetime, only one of Van Gogh’s paintings, The Red Vineyard, was sold.
