- S’Klallam and Chemakum Indian tribes on Olympic Peninsula when Jarman settled there in 1848-52 (skagitriverjournal.com)
We spun this story off from the William “Blanket Bill” Jarman biography in order to address the considerable confusion and contradiction in various accounts about the tribes present on the Olympic Peninsula when Jarman settled there temporarily, off and on, in the period 1848-52. The contradictions were present in both the contemporary U.S. Government documents of that time, private writing later in the century and books by various historians between then and now. In our review, we will also explain the genealogy of Alice, Jarman’s wife and companion for the next three decades. She and the Indians that Jarman met in that period helped shape both his life and the legends about him.
- 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.
