**************************************************************************** ADSP-BF535 EZ-KIT Lite Assembly based Cache Analog Devices, Inc. DSP Division Three Technology Way P.O. Box 9106 Norwood, MA 02062 Date Created: 1/30/02 This example shows how to configure the ADSP-BF535 to run with L1 memory configured as cache. Files contained in this directory: readme.txt this file cache_example.asm assembly file for cache example cache_example.dpj VisualDSP++ project file cache_example.dxe executable for this project cache_example.ldf linker description file _______________________________________________________________________________ CONTENTS I. FUNCTION/ALGORITHM DESCRIPTION II. IMPLEMENTATION DESCRIPTION III. OPERATION DESCRIPTION I. FUNCTION/ALGORITHM DESCRIPTION L1 Memory is configured as cache to run a simple blink program. II. IMPLEMENTATION DESCRIPTION Since the cache-line valid bits come up in a random state at reset, the first thing we need to do is clear each valid bit in both the data and instruction L1 caches. The next thing we need to do is to set up the CPLBs for data and instruction memory. The CPLB setup provided here is very basic. Once CPLB's are defined, cache can be enabled. There is a small blink program which is located in L2 memory. This code is actually cached in this example. III. OPERATION DESCRIPTION - Open the project "cache_example.dpj" in the VisualDSP Integrated Development and Debugger Environment (IDDE). - Under the "Project" tab, select "Build Project". - Open a ADSP-BF535 EZ-KIT Lite session in the Debugger. - Load "cache_example.DXE" - Place breakpoints as desired to see the operation of the program. - Focus on the ADSP-BF535 and select "RUN" from the menu bar. - View the LEDs on the EZ-KIT Lite to see the blinking in action.
