ADSP-2192M
16-Bit PCI DSP I/O Memory Map (BAR4)
PCI Base Address Register (BAR4) allows indirect access to the
ADSP-2192M Control Registers and DSP Memory. The DSP
Memory Indirect Access Registers accessible from BAR4 are
shown in
Table 10
.
DSP P0 Memory Indirect Address Space occupies PCI BAR4
Space 0x000000 through 0x01FFFF
DSP P1 Memory Indirect Address Space occupies PCI BAR4
Space 0x020000 through 0x03FFFF
All Indirect DSP Memory Accesses are 24-bit or 16-bit Word
Accesses.
Using the USB Interface
The ADSP-2192M USB design enables the ADSP-2192M to be
configured and attached to a single device with multiple inter-
faces and various endpoint configurations, as follows:
1. Programmable descriptors and a class-specific com-
mand interpreter are accessible through the USB 8052
registers. An 8052 compatible MCU is supported
on-board, to enable soft downloading of different config-
urations, and support of standard or class-specific
commands.
2. A total of eight user-defined endpoints are provided.
Endpoints can be configured as BULK, ISO, or INT,
and can be grouped.
