Stack, RT Circular Buffers, MT Command Stack, and MT Data Stack; BC Op
Code Parity Error, (RT) Illegal Command, (BC) General Purpose Queue or
(RT/MT) Interrupt Status Queue Rollover, Call Stack Pointer Register Error, BC
Trap Op Code, and four User-Defined interrupts for the Enhanced BC mode.
RAM PARITY
The BC/RT/MT version of the PCI Enhanced Mini-ACE is available with options of
4K or 64K words of internal RAM. For the 64K option, the RAM is 17 bits wide. The
64K X 17 internal RAM allows for parity generation for RAM write accesses, and
parity checking for RAM read accesses. When the PCI Enhanced Mini-ACE
detects a RAM parity error, it reports it to the host processor by means of an
interrupt and a register bit. Also, for the RT and Selective Message Monitor modes,
the RAM address(es) where a parity error(s) was detected will be stored on the
Interrupt Status Queue (if enabled).
RELOCATABLE MEMORY MANAGEMENT LOCATIONS
In the PCI Enhanced Mini-ACE’s default configuration, there is a fixed area of
shared RAM addresses, 0000h-03FF, that is allocated for storage of the BC’s or
RT’s pointers, counters, tables, and other “non-message” data structures. As a
means of reducing the overall memory address space for using multiple PCI
Enhanced Mini-ACEs in a given system (e.g., for use with the DMA interface
configuration), the PCI Enhanced Mini-ACE allows this area of
RAM to be
relocated by means of 6 configuration register bits. To provide backwards
compatibility to ACE and Mini-ACE (Plus), the default for this RAM area is 0000h-
03FFh.
Figure 12 illustrates a generic connection diagram between a PCI “Master” and a
PCI PCI Enhanced Mini-ACE “Target.” Figures XX and XX illustrate read and write
timing.
