1.2 Central Processor Unit
1.2 Central Processor Unit
The Central Processor Unit (CPU) chip is a 32-bit virtual memory
microprocessor with integral floating point capability and on-chip cache,
derived from the CVAX CPU, CFPA floating point unit and CVAX clock chips.
The CPU key features are
Feature Description
Subset of VAX computer
data types Byte, word, longword, quadword, character string, variable- length bit field, and support for f_floating and g_floating
point data types.
Full base instruction
group Integer and logical, address, variable-length bit field, control, procedure call, queue, character string instructions
CMPC3/CMPC5, LOCC, MOVC3/MOVC5, SCANC, SKPC
and SPANC, and operating system support. f_floating,
The CFP chip supports d_floating and g_floating point
instructions.
Full VAX memory
management Includes a demand paged memory management unit fully compatible with VAX computer memory management.
System space addresses are virtually mapped through
single-level page tables; process space addresses are
virtually mapped through double-level page tables.
Supports four gigabits of virtual memory and up to one
gigabits of physical memory.
On-chip memory cache The CPU chip has 8 Kbytes of on-chip cache to improve
execution times by minimizing the use of the memory
subsystem.
