31. It was a single-accumulator machine much like a DEC PDP-8, except using 16-bit instructions and data instead of 12 bits. 32. A VLIW is called a molecule and has room to store eight 32-bit instructions ( called atoms ) per cycle. 33. In 1.6 . 0, the 32-bit instructions of the ARMv8 ( AARCH64 ) architecture are emulated, but 64-bit instructions are unsupported. 34. In 1.6 . 0, the 32-bit instructions of the ARMv8 ( AARCH64 ) architecture are emulated, but 64-bit instructions are unsupported. 35. Like the earlier designs, the 400 and 500 used the same 14-bit address space and 24-bit instruction set and were compatible. 36. Parallax's SX are 8-bit RISC microcontrollers, using a 12-bit instruction word, which run fast at 75 MHz ( 75 MIPS ). 37. Easy answer : The vast majority of the software we're using right now was designed around older processors that understood 16-bit instructions . 38. In 1985, Intel released the 80386, the first x86 microprocessor with a 32-bit instruction set and a memory management unit with paging. 39. Its 3 operands are used along with those of the following instruction word to produce additional 32-bit instructions with up to six operands. 40. This technique packs two 16-bit instructions into one 32-bit instruction, which is then unpacked at the decode stage and executed as two instructions.
