Abstract

A computer has a CPU (10) comprising central ALU (12) operating in conjunction with stack means (16), decode logic (20) and microcode control store (18). The stack means (16) is adapted to hold a mixture of microcode and higher level languages, each with separate stack pointer in a corresponding number of registers (32), to enable nested and recursive routines to be implemented directly. The ALU (12) is connected to backing store (26) and core store (14) only via an autonomous pager/indexer (28) in an arrangement which makes page faults invisible to the ALU. The backing store (26) and core store (14) form a one-level, heap-based structure in which data is held in a common format. A novel form of garbage collection from core store is also described.
