Many manufacturers will sell you a low cost evaluation kit, allowing you toexperience their products first-hand. These are a great educational tool; it doesn't matter if youare a novice or a pro, they are the best way to become familiar with a particular DSP. Forinstance, Analog Devices provides the EZ-KIT® Lite to teach potential customers about itsSHARC® family of Digital Signal Processors. For only $179, you receive all the hardware andsoftware you need to see the DSP in action. This includes "canned" programs provided with thekit, as well as applications you can write yourself in assembly or C. Suppose you buy one ofthese kits from Analog Devices and play with it for a few days. This chapter is an overview ofwhat you can expect to find and learn.The ADSP-2106x familyIn the last chapter we looked at the general operation of the ADSP-2106x"SHARC" family of Digital Signal Processors. Table 29-1 shows the variousmembers of this family. All these devices use the same architecture, but havedifferent amounts of on-chip memory, a key factor in deciding which one touse. Memory access is a common bottleneck in DSP systems. The SHARCDSPs address this by providing an ample supply of on-chip dual-ported SRAM.However, the last thing you want to do is pay for more memory than you need.DSPs often go into cost sensitive products, such as cellular telephones and CDplayers. In other words, the organization of this family is determined bymarketing as well as technology. The oldest member of this family is the ADSP-21020. This chip contains thecore architecture, but does not include on-chip memory or I/O handling. Thismeans it cannot function as a stand-alone computer; it requires externalcomponents to be a functional system. The other devices are complete The Scientist and Engineer's Guide to Digital Signal Processing536PRODUCT Memory NotesAD14604 Mbit ×4Quad-SHARC, Four ADSP-21060's in thesame module; provides an incredible 480MFLOPS in only 2.05"×2.05"×0.16".

Not quite a SHARC DSP.TABLE 29-1Members of the SHARC family.computers within a single chip. All they require to operate is a source ofpower, and some way to load a program into memory, such as an externalPROM or data link.Notice in Table 29-1 that even the low-end products have a very significantamount of memory. For instance, the ADSP-21065L has 544 kbits of internalSRAM. This is enough to hold 6-8 seconds of digitized speech (8k samples persecond, 8 bits per sample). On the high-end of the family, the ADSP-21060has a 4 Mbit memory. This is more than enough to store an entire digitizedimage (512×512 pixels, 8 bits per pixel). If you require even more memory,you easily add external SRAM (or slower memory) to any of these devices. In addition to memory, there are also differences between these GETTING STARTED Getting started Grammar: Questions Vocabulary: Introductions Complete the text Italy for my job in a bank school university listening quickly understand from all over the world words my favourite songs Mary’s questions Where are you from Gianni?
