example 1

[0066] NOR flash with 16-bit bus width: 16 x data + 25 x address + 5 x control = 46 leads / pin

[0067] Typical maximum speed: read 128MByte / s, write 1.2MByte / s

example 2

[0069] eMMC (managed NAND flash) with 8-bit bus width: 8 x data + 3 x control = 11 leads / pin

[0070] Typical maximum speed: read 44MByte / s, write 20MByte / s

[0071] Whereas the RAM interface with 32-bit width still exists and runs e.g. at 533MHz (or greater):

[0072] 533MHz DDR*32 bits=1066T / s*4Byte=Maximum 4264GByte / s

[0073] Other interfaces are typically provided to persistent storage 204, but all persistent storage requires its own special interface and has a similar cost-speed dilemma.

[0074] figure 2 The principle structure of the assembly according to the invention is shown. Shown is a microcontroller 206 with a fast working memory interface 210 via a memory management unit 212, which connects a fast volatile memory 202 (RAM) to the system via an external bus.

[0075] What is new is a fast stand-alone processor 234 (controller) connected in the middle, which provides a standardized RAM module interface (JEDEC, eg JESD79) via interface 240 . The standardized ...

Abstract

The invention relates to a method (660) for transmitting data within a computer system (200) between a memory interface (208) of a volatile memory (202), a memory interface (214) of a non-volatile memory (204) and an interface (210) of a microcontroller (206), wherein the method (660) comprises a step of reading in (662) data from the memory interface (214) of the non-volatile memory (204) in response to an information and a step of providing (664) the read-in data at the memory interface (208) of the volatile memory (202).

Description

technical field [0001] The invention relates to a method for transmitting data within a vehicle computer system, a corresponding storage management device, a corresponding storage system, a corresponding computer system for a vehicle and a corresponding computer program. Background technique [0002] Today's computer systems basically work with two types of memory: fast volatile memory (Random Access Memory RAM) and different types of non-volatile memory (Read Only Memory ROM, Flash Memory, Disk). In this context, flash memories are primarily used as permanent storage in the field of mobile systems, which also includes smartphones and tablet computers, and in particular also infotainment systems in vehicles or motor vehicles. For historical reasons this runs at a different interface. [0003] The allocation of the two memory types applications is due to their different characteristics. The non-volatile memory first contains the program code that each computer essentially n...
