The resource manager polls all the ME to core rings at regular intervals. A look at the thread.c file in the src/microace/common/resource_manager/driver directory will help. -- Shyamal Pandya Cogito, ergo sum! Addr: 920 S Terrace Rd #102 Tempe AZ 85281 Phone: 1-480-96601982

Hi,

Does anyone know how the Microengine pass the exceptional packets to the StrongARM? If we use Resource Manager in MicroACE, there is a ring buffer between them and the Microengine puts data into it. How does the Resource manager know there is a packet in the buffer? by polling or interrupt?

Thanks.
