Implementing DSPs with programmable logic

Article Abstract:

Many designers are beginning to view programmable logic as a solution to process signals digitally. Programmable logic devices (PLDs) have been utilized to process signals for some time, although not in mainstream applications. One of the first forays was in television mixing boards and special-effects modules, for real-time image manipulation and enhancement. PLDs are appealing compared to other options because they provide the time-to-market and the flexibility advantages of general purpose DSPs and the performance of application-specific standard products (ASSPs) and ASICs. In addition, PLDs add attractive pricing for medium and low volumes. The price for PLDs has decreased significantly between 1991 and 1996, averaging a 30% decrease each year. The per-device cost of PLDs still does not mimic that of ASICs or standard DSPs for high volume, the biggest number of users are not in the consumer sector or other high volume applications.

Choosing the right source for pre-created designs

Article Abstract:

Logic designers have to make efficient use of intellectual property (IP) to keep pace with the rapid development of high-density programmable logic devices (PLD). IPs are pre-created designs that easily integrate into a system-level chip. The four major sources of IP are EDA companies, in-house libraries, silicon vendors and independent developers, all of which provide a range of complicated functions including DSP cores and microcontrollers and PCI interface designs in a number of formats such as hard macros, mask sets, VHDL or Verilog description and schematics. These products range in size from 2K to 200K and are pre-defined and pre-tested. IP from a tool supplier's library is well-integrated for creating a company's toolset and offers technology and architectural independence. Independent IP developers typically specialize in a specific area of design such as communications or microcontroller design.

DSPs can build cheaper, efficient control systems

Article Abstract:

Complex control software can decrease the cost and energy consumption of control systems by providing for the use of less memory, cheaper motors and fewer system sensors. Such systems are quickly moving to implement DSPs to get the real-time MIPS and the tightly integrated peripherals required to introduce high-end control at low-end prices. DPSs are the processor of choice for numerous embedded control applications taking the place of microcontrollers. Currently, DSPs are quickly penetrating embedded applications, such as graphics systems, computers, wireless communications systems, consumer electronics, appliances and mass-storage devices. The main function of nearly all control systems is controlling the motor. The versatility, integration and performance of 16-bit DSPs provide for the design of very complicated by inexpensive controllers for cheap AC motors.
