For the TMSC Pin PowerPAD plastic quad flatpack, the external . Another key feature of the C67x CPU is the load/store architecture, where all. C DSK Features. • A Texas Instruments TMSC DSP operating at MHz. • An AIC23 stereo codec. • 16 Mbytes of synchronous DRAM. Starter Kit (DSK), based on the TMSC floating point DSP running at MHz. The C processor has KB of internal memory, and can potentially address a pretty good idea of the TMSC architecture and features.

In this mode, the DAGs are configured to generate t,s320c6713 addresses into the circular buffers, a necessary part of the FFT algorithm. Digital Filters Match 2: For short this DSP will be. In fact, dssp we were executing random instructions, this situation would be no better at all.

The Von Neumann design is quite satisfactory when you are content to execute all of the required tasks in serial. First, let’s look at how the instruction cache improves the performance of the Harvard architecture. The Codec has 4 channels: A handicap of the basic Harvard design is that the data memory bus is busier than zrchitecture program memory bus. We only need other architectures when very fast processing is required, and we are willing to pay the price of increased complexity.

Download this chapter in PDF format Chapter Program Language Execution Speed: There are also many important features of the SHARC family architecture that aren’t shown in architectjre simplified illustration. In addition, an abundance of circular buffers greatly simplifies DSP code generation- both for the human programmer as well as high-level language compilers, such as C.


This includes datasuch as samples from the input signal and the filter coefficients, as well as program instructionsthe binary codes that go into the program sequencer.


When two numbers are multiplied, two binary values the numbers must be passed over the data memory bus, while only one binary value the program instruction is passed over the program memory bus. Block diagram of frequency multiplier: In the jargon of the field, this efficient transfer of data is called a high memory-access bandwidth.

As an example, suppose you write an efficient FIR filter program using coefficients. In comparison, an interrupt in the SHARC family is handled by moving the internal data into the shadow registers in a single clock cycle.

Why so many circular buffers? Everything else is secondary. You can expect it to require about to clock cycles per sample to execute i. These control the addresses sent to the program and data memories, specifying where the information is to be read from or written to.

The data paths are described in more detailin Chapter 2.

Dzp feature allows step 4 on our list managing the sample-ready interrupt to be handled very quickly and efficiently. In addition, the standard multichannel buffered serial port McBSP may be used to communicate with serial peripheral interface SPI mode peripheral devices.

It is used to communicate between Codec and DSP. The first time through a loop, the program instructions must be passed over the program memory bus. The main buses program memory bus and data memory bus are also accessible from outside the chip, providing an additional interface to off-chip memory and peripherals.

In fact, most computers today are of the Von Neumann design. This means that each DAG holds 32 variables 4 per bufferplus the required logic.

This is a small memory that contains about 32 of the most recent program instructions. Table of contents 1: Since the buses operate independently, program instructions and data can be fetched at the same time, improving the speed over the single bus design. However, DSPs are designed to operate with circular buffersand benefit from the extra hardware to manage them efficiently. This means that all of the memory to CPU information transfers can be accomplished in dspp single cycle: Filter Comparison Match 1: The components required to perform experiments using this kit are: As shown in aa Von Neumann architecture contains a single memory and a single bus for transferring data into and out of the central processing unit CPU.
