80 * This function initialises the NpeMgr module.
81 * It should be called before any other function in this module is called.
82 * It only needs to be called once, but can be called multiple times safely.
83 * The code will ASSERT on failure.
86 * - It must be called before any other function in this module
89 * - NPE Configuration Register memory space will be mapped using
90 * IxOsal. This memory will not be unmapped by this module.

103 * This function will uninitialise the IxNpeDlNpeMgr sub-component.
104 * It should only be called once, and only if the IxNpeDlNpeMgr sub-component
105 * has already been initialised by calling @ref ixNpeDlNpeMgrInit().
106 * No other IxNpeDlNpeMgr sub-component API functions should be called
107 * until @ref ixNpeDlNpeMgrInit() is called again.
108 * If possible, this function should be called before a soft reboot or unloading
109 * a kernel module to perform any clean up operations required for IxNpeMh.

156 * @brief sets a NPE to RESET state
158 * @param IxNpeDlNpeId [in] npeId - id of target NPE
160 * This function performs a soft NPE reset by writing reset values to the
161 * Configuration Bus Execution Control registers, the Execution Context Stack
162 * registers, the Physical Register file, and the Context Store registers for
163 * each context number. It also clears inFIFO, outFIFO and Watchpoint FIFO.
164 * It does not reset NPE Co-processors.
167 * - The NPE should be stopped beforehand
170 * - NPE NextProgram Counter (NextPC) will be set to a fixed initial value,
171 * such as 0. This should be explicitly set by downloading State
172 * Information before starting NPE Execution.
173 * - The NPE Instruction Pipeline will be in a clean state.
176 * - IX_SUCCESS if the operation was successful
177 * - IX_FAIL if the operation failed

191 * Ensures only background Execution Stack Level is Active, clears instruction
192 * pipeline, and starts Execution on a NPE by sending a Start NPE command to
193 * the NPE. Checks the execution status of the NPE to verify that it is
