Instruction cache tuning for embedded multitasking applications

S.K. Dash, T. Srikanthan
<span title="2010-11-01">2010</span> <i title="Institution of Engineering and Technology (IET)"> <a target="_blank" rel="noopener" href="https://fatcat.wiki/container/34xrdbeizvba5cnrxymhir5cxi" style="color: black;">IET Computers &amp; Digital Techniques</a> </i> &nbsp;
The proposed techniques are also highly scalable and can be relied upon to predict the instruction cache hit rate for any range of instruction cache sizes after a one-time simulation and profiling.  ...  Cache tuning for RTOS-driven multitasking applications is achieved by intelligently separating the user tasks and RTOS components and profiling them in isolation to identify the nature of loops in them  ...  This reuse distance information can then be used to estimate the hit/miss rate for multiple cache sizes.  ...

An embedded RTOS dynamically schedules multiple tasks onto the PE's. Process synchronization is achieved using cached semaphores.  ...  Each PE contains a 32-b RISC core with DSP enhancements and a 64-b single-instruction, multiple-data vector coprocessor with four 16-b MAC/s and a vector reduction unit.  ...  In the case of a cache hit, the output of the data RAM is driven to IDATA (for instruction cache) or MDATA (for data cache).  ...

The trace compressor requires an on-chip area that is equivalent to one third of a 1 kilobyte cache and it allows for continual and unobtrusive program tracing in real-time.  ...  Our mechanism requires only 0.15 bits/instruction/CPU on average on the trace port, which is a six-fold improvement over state-of-the-art commercial solutions.  ...  ACKNOWLEDGMENT The authors would like to thank the anonymous reviewers for their valuable suggestions. This work was supported in part by a National Science Foundation grant CNS-0855237.  ...

High-performance timing simulation of embedded software

<span title="">2008</span> <i title="ACM Press"> <a target="_blank" rel="noopener" href="https://fatcat.wiki/container/5vn6yyeefbbxtoo3uhwxwjwtme" style="color: black;">Proceedings of the 45th annual conference on Design automation - DAC &#39;08</a> </i> &nbsp;
This paper presents an approach for cycle-accurate simulation of embedded software by integration in an abstract SystemC model.  ...  This allows the consideration of data dependencies during run-time and the incorporation of branch prediction and cache models by efficient source code instrumentation.  ...  After that, a function call to the cache handling model is added. This code uses a cache model to find out possible cache hits or misses.  ...
