Integrated Byte Instruction Processor (IBIP)

alias Daffodil/Daisy "P-chip"


Architecture Features:


o Dandelion CP "look-alike"
Existent microcode is "transportable" (Mesa, InterLisp, Smalltalk)
16-bit data paths

o No microtasking
No click structure, No "c1-c2-c3 waltz"

o Off-chip Microstore
48-bit Microinstruction
8K Microstore (up to 64K)

o Byte code instruction fetch unit (IFU)
8 Bytes

o "Self-timed" memory interface (AP bus)
Double word fetch

o On-chip clock generator
Clock is suspended while waiting for A Chip
