The PDP-11, VAX-11 (usually just VAX), and Alpha have been the strategic computer hardware architectures of Digital The PDP-11 is a CISC architecture with a 16-bit virtual address. The first PDF'-11 implementation -the The second was the instruction set and the instruction set encoding. The PDP-11 model is appealing due to its simplicity and its portability; however, lack of memory-safety proper-ties leaves code compiled to that model subject to We discuss the problems with supporting these idioms on existing models, including our CHERI ISA (a RISC instruction-set architecture that Unix PDP-11 Emulator. 1. Filename Conventions 2. The Assembler 2.1. Instructions 2.4.1. PDP-11 Mnemonics 2.4.2. Assembler Directives (Pseudo-Ops) 2.5. In fact, these are set up from a configuration file, read in at start up. This is the reason why you have to poll the busy bit repetitively. ERSATZ-11 PDP-11 EMULATOR. VERSION 7.3. Copyright c 1993-2017 by Digby's Bitpile, Inc. All rights reserved. Bob Supnik, formerly of DEC, and Alan Sieving of QED provided valuable details of poorly documented PDP-11 instruction set semantics. PDP-11 Model 20 Instruction Set (Basic Instruction Set). A. formal description of the basic instruction set is given in. Reserved op code Hove i nstruct ion.

The wiki page PDP-11 architecture has a cryptic paragraph with no references or examples The fact that no implementation was regarded as correct deserves another question: was there another instruction set architecture with similar inconsistencies without an officially declared correct way of PDP-11 instruction reference CSC 258 Overall notes Most numbers in this document are in octal (base 8). ''msb'' means ''most significant bit'' (sometimes 0; else V set iff div result would not fit in reg V set iff msb of [reg] changed during shift; C = last bit shifted out V set iff msb changed; C = last bit shifted A PDP-11 target for lcc. I have made this commentary as a straightforward case study which I hope might assist anyone else who is trying to retarget lcc. It was also an opportunity to complete my knowledge of the One True Instruction Set. If the other implementation surfaces, it may provide an PDP-11 simulator V4.0-0 Beta git commit id: 592deb8f Configuring PDP-11/20 with 16Kb of RAM Disabling XQ Loading BASIC paper tape image The next few instructions shift the TRAP right to see if bit 0 is set, and if it is not, then the TRAP instruction is restored by shifting it left again, and A PDP-11 target for lcc.
