Memory Map
The ADSP-21161N processor includes 1 MB of internal SRAM for pro-
gram storage or data storage. The configuration of internal SRAM is
detailed in the ADSP-21161 SHARC Processor Hardware Reference.
The ADSP-21161N EZ-KIT Lite board contains 512K x 8-bits of exter-
nal flash memory. The flash memory connects to the processors's
memory select pins. The flash memory can be accessed in either the
~BMS
boot memory space or the external memory space. The external memory
interface also connects to three 8M x 16-bit synchronous dynamic random
access memory (SDRAM). The SDRAM memory connects to the
memory select pin.
