9 / 36 page  ADSP-2104/ADSP-2109 REV. 0 –9– ADSP-2109 Prototyping You can prototype your ADSP-2109 system with the ADSP- 2104 RAM-based processor. When code is fully developed and debugged, it can be submitted to Analog Devices for conversion into a ADSP-2109 ROM product. The ADSP-2101 EZ-ICE emulator can be used for develop- ment of ADSP-2109 systems. For the 3.3 V ADSP-2109, a voltage converter interface board provides 3.3 V emulation. Additional overlay memory is used for emulation of ADSP-2109 systems. It should be noted that due to the use of off-chip overlay memory to emulate the ADSP-2109, a performance loss may be experienced when both executing instructions and fetching program memory data from the off-chip overlay memory in the same cycle. This can be overcome by locating program memory data in on-chip memory. Ordering Procedure for ADSP-2109 ROM Processor To place an order for a custom ROM-coded ADSP-2109, you must: 1. Complete the following forms contained in the ADSP ROM Ordering Package, available from your Analog Devices sales representative: ADSP-2109 ROM Specification Form ROM Release Agreement ROM NRE Agreement & Minimum Quantity Order (MQO) Acceptance Agreement for Pre-Production ROM Products 2. Return the forms to Analog Devices along with two copies of the Memory Image File (.EXE file) of your ROM code. The files must be supplied on two 3.5" or 5.25" floppy disks for the IBM PC (DOS 2.01 or higher). 3. Place a purchase order with Analog Devices for nonrecurring engineering changes (NRE) associated with ROM product development. After this information is received, it is entered into Analog Devices’ ROM Manager System which assigns a custom ROM model number to the product. This model number will be branded on all prototype and production units manufactured to these specifications. To minimize the risk of code being altered during this process, Analog Devices verifies that the .EXE files on both floppy disks are identical, and recalculates the checksums for the .EXE file entered into the ROM Manager System. The checksum data, in the form of a ROM Memory Map, a hard copy of the .EXE file, and a ROM Data Verification form are returned to you for inspection. A signed ROM Verification Form and a purchase order for production units are required prior to any product being manufactured. Prototype units may be applied toward the minimum order quantity. Upon completion of prototype manufacture, Analog Devices will ship prototype units and a delivery schedule update for production units. An invoice against your purchase order for the NRE charges is issued at this time. There is a charge for each ROM mask generated and a mini- mum order quantity. Consult your sales representative for details. A separate order must be placed for parts of a specific package type, temperature range, and speed grade. |
