remora - Implementing audio processing and control interfaces on the 21489 SHARC DSP

Requirements

• Hardware:

  • Evaluation Board(EVB)
  • Emulator
  • USB-UART Adapter

• Software:

  • CrossCore Embedded Studio(CCES)
  • Visual Studio

Command Line Device Programmer(CLDP)

• Processor:

  • -proc ADSP-21479: Select ADSP-21479
  • -proc ADSP-21489: Select ADSP-21489
  • vice versa.

• Emulator Models and Configuration:

  • -emu ice-1000: AD-HP510ICE compatible.
  • -emu kit: Supports EZ-KIT Debug Agent.

• For serial booting, execute this command:

  cldp -proc ADSP-21479 -emu kit -driver "directory\to\driver\21479_m25p16_dpia.dxe" -cmd prog -erase all -format ascii -file "directory\to\program\in-application-programming.ldr"

• For parallel booting, use the following command:

  cldp -proc ADSP-21479 -emu kit -driver "directory\to\driver\21479_m29w320_dpia.dxe" -cmd prog -erase affected -format hex -file "directory\to\program\in-application-programming.ldr"

Things I easily forget

• Boot Mode Selection(Compiled option in CCES):

  • SPI Flash: For serial booting.
  • PROM: For parallel booting.

• EZ-KIT Boot Encoding Options(Rotatary switch on EZ-KIT):

  • 0: SPI Slave Boot.
  • 1: Boot from SPI Flash Memory (SPI Master Boot).
  • 2: Boot from 8-bit External Parallel Flash Memory (Default).

Overview

This project utilizes an Evaluation Board(EVB) purchased from Alibaba at a cost of $60. The EVB is equipped with high-quality audio components, including a 21489 SHARC DSP, a flash, a SDRAM, a PSU, an ADC-PCM1804, and a DAC-PCM1798, ensuring high fidelity quality.

An emulator, crucial for programming the EVB, was also sourced from Alibaba. This un-authorized unit(AD-HP510ICE), priced at $200, provides a cost-effective alternative to the official emulator(ICE-1000/ICE-2000), which is priced around $2,000.

Additionally, a USB-UART adapter was adopted for serial communication purposes. Priced at approximately $5, this adapter underscores our commitment to cost-efficiency without compromising on performance.

Overall, this setup offers an affordable and robust solution for developing high-quality audio DSP solutions in 2021.
