Hi, I would like to know name of some Real Time Operating System for ADSP-2181, and company which produces this RTOS. Can anybody tell me is there posibility to store entire context of the ADSP-2181 processor, I mean not only data regs, but also stacks - PCSTACK, LOOP Stack, etc., in some structure, when switching from one task to another task on interrupt coming. With best regards Mr. Miroslav Rousenov |

Hi, At present, threr is no company that provides RTOS for ADSP218x. But ere is company called Express Logic that providesRTOS for ADSP2106x. You might apprach Express logic and ask them to port ThreadX for ADSP218x. Once agian, it depends on the kind of business you are ready to offer to them. You can search for ThreadX in web based search engine and get more info on it.

Hi, Can some explain to me why the integer multiplication leaves the result shifted one bit to the left. if mx0 = 10h and my0 = 10h then ie mr = mx0 * my0 (ss) leaves mr = 200h when it should be 100h. There is mention of 1.15 format and 16.0 format with respect to MSTAT (I think) but even changing this bit doesn't change the result. I presume the reason is to give you a fast multiplier that only takes one clock cycle, and you shift it right if you need to or half the magnitude of your FIR co-efficients, etc.... Any ideas are appreciated. Regards, Luke ------------------------------- Luke Enriquez (VK3EM) Trio Communications 2000 Pty. Ltd. Electronics Design Engineer. 41 Aster Ave. B.Eng (Comms) Hon.
