FIG. 1 is a schematic diagram of an electronic device 100 according to an embodiment of the invention. The electronic device 100 can include a microprocessor 110 and a memory 120. The memory 120 can include a data memory 12, and can further include a program memory 124 such as an instruction memory, wherein the data memory 122 can include a plurality of data storage areas (not shown in FIG. 1). The microprocessor 110 and the memory 120 can be coupled to each other. For example, the data memory 122 and the program memory 124 can be coupled to the microprocessor 110 through the data bus and the program bus, respectively, but the invention is not limited thereto. The memory 120 can be used to store information. For example, the data memory 122 and the program memory 124 can store the program data 122D and the program code 124P, respectively. In this embodiment, the memory 120 (for example, the data memory 122 and the program memory 124) may be a random access memory, and the electronic device 100 may further include a non-volatile memory (NV memory) 130. The code 124P can be loaded from the non-volatile memory 130 to the program memory 124, but the invention is not limited thereto. According to some embodiments, the non-volatile memory 130 is not required to be disposed in the electronic device 100, and the code 124P can be loaded from the outside of the electronic device 100 to the program memory 124. According to some embodiments, the memory 120 can be any type of memory (eg, non-volatile memory). Examples of the electronic device 100 may include, but are not limited to, a storage device (such as a flash drive, a hard disk drive, a solid state drive), a television, a monitor, a wearable device, a multi-function mobile phone, a personal computer, or Any other type of electronic device. In particular, the electronic device 100 can be a multi-port electronic device.

The microprocessor 110 can execute a program code 124P, such as a set of code of the electronic device 100, to control multiple operations of the electronic device 100, which can respectively correspond to various functions of the electronic device 100. The plurality of operations includes a predetermined operation that can correspond to one of the various functions described above. For example, the set of code may include a predetermined program module for controlling the predetermined operation, the predetermined program module may include a partial program, and the partial program may provide a variable access service to the predetermined program module. To reduce the chance that the predetermined program module accesses the array variables (for example, to prevent the predetermined program module from accessing any array variables).

For ease of understanding, it is assumed that the conventional method uses the array variable variable[x] to store the variables of each 埠 of an electronic device, where x = 0 represents 埠0, x = 1 represents 埠1, and so on. The above array variable variable [x] is not only used once, and there are many other array variables in the various operations of this electronic device. If the designer attempts to give the electronic device a lot of functions, the access operations (such as reading and writing) of the various array variables will make the overall machine code of the firmware of the electronic device become large, and Cannot be placed in a limited memory storage space. Therefore, designers are forced to abandon some features.

In contrast, the present invention can effectively solve the problem. FIG. 2 is a diagram showing the data memory configuration 200 of the electronic device 100 shown in FIG. 1 in an embodiment. The shared memory storage area SHM and the data storage area {PM(0), PM(1), ..., PM(N - 1)} may be located in the data memory 122 shown in Fig. 1, wherein the program data The 122D can include data in the data memory configuration 200. The method of the present invention can change all array variables to general variables, that is, non-array variables, and can exchange data through the shared memory storage area SHM to manipulate all N 埠 variables. For example, the variables from 埠0 to 埠(N - 1) can be stored in the exclusive data storage areas {PM(0), PM(1), ..., PM(N - 1)}, respectively, and will not be affected by each other. Since the array variable variable[x] is changed to a general variable (such as the variable VARIABLE) to reduce the machine code of the microprocessor grabbing the address x, the more the number of variables or the more the number of variables being manipulated, Then the greater the amount of machine code reduction.

For ease of understanding, the variables 埠0 to 埠(N - 1) can be used as examples of the data in the data storage areas {PM(0), PM(1), ..., PM(N - 1)}, but the present invention Not limited to this. According to some embodiments, any other type of variable may also be used as an example of data in the data storage area {PM(0), PM(1), ..., PM(N - 1)}.

FIG. 3 is a flow chart of a method 300 for performing hardware resource management in an electronic device in accordance with an embodiment of the invention. The method 300 can be applied as an example of the method of the present invention described above, and can be applied to the electronic device 100 shown in FIG.

In step 310, the electronic device 100 loads the program code 124P (such as the above-mentioned set of code) into the program memory 124 to allow the microprocessor 110 to execute the program code 124P. For example, the set of code may not contain any array variables, but the invention is not limited thereto.

In step 320, the microprocessor 110 executes at least a portion of the code 124P to control the electronic device 100.

In step 330, the microprocessor 110 executes the partial program to control the electronic device 100 to perform the predetermined operation. For example, the local program can be a variable access service loop, and the microprocessor 110 can perform the variable access service loop according to the index X, so as to control the electronic with the change of the index X in the variable access service loop. The device 100 performs the predetermined operation, but the present invention is not limited thereto.

According to this embodiment, the microprocessor 110 can control the electronic device 100 to perform the predetermined operation according to the following steps a to g: a. Let X = 0; b. If X < N, go to step c, otherwise, go to step g; c. Copy the data storage area PM(X) corresponding to the index X to the shared memory storage area SHM, for example, copy the data corresponding to the index X from the data storage area PM(X) corresponding to the index X to the shared memory At least one shared variable (eg, a shared variable VARIABLE, or a plurality of shared variables {variable1, variable2, variable3, ...}) in the storage area SHM, wherein the at least one shared variable is a non-array variable, and the plurality of data storage areas include a shared memory storage area SHM and a data storage area PM(X) corresponding to the index X; d. operating a general variable located in the shared memory storage area SHM, for example, operating the at least one shared variable (eg, sharing variables) The data in the VARIABLE, or the shared variable {variable1, variable2, variable3, ...}), to control the electronic device 100 to perform at least a portion of the predetermined operation, wherein the at least one shared variable is operated The material may include accessing the data in the at least one shared variable; e. copying the shared memory storage area SHM to the data storage area PM(X) corresponding to the index X, for example, updating the latest data in the at least one shared variable Copying the at least one shared variable (eg, shared variable VARIABLE, or shared variable {variable1, variable2, variable3, ...}) from the shared memory storage area SHM to the data storage area PM(X) corresponding to the index X; f. Let X = X + 1 and proceed to step b; g. End; wherein the operation of step 330 may comprise at least a portion (eg, a portion or all) of steps a through g, particularly steps c through e, and steps b through f are formed The loop can be used as an example of the variable access service loop.

The method according to the present invention, such as method 300, by means of the variable access service, the amount of machine code of at least a portion of the code of the set of codes has become smaller, such that a memory of the electronic device 100 (eg, the program memory 124, or The storage capacity of any other type of memory is sufficient to store the set of code (i.e., the set of code has become smaller and smaller enough to be placed into the memory). In particular, through the variable access service, all of the required array variables in the predetermined program module have been replaced with respect to the at least one shared variable (eg, shared variable VARIABLE, or shared variable {variable1, variable2, variable3, respectively). A plurality of access operations are performed to reduce the amount of machine code in the program memory 124 of the predetermined program module (which represents the size of the predetermined program module in the program memory 124). For example, through the variable access service, when the set of code is loaded into the program memory 124, the predetermined program module in the set of codes has become smaller (for example, has been minimized), but the present invention does not Limited to this. It is assumed that the plurality of operations of the electronic device 100 respectively correspond to a plurality of functions of the electronic device 100, and the predetermined operation corresponds to one of the plurality of functions. For example, through the variable access service, the code corresponding to the predetermined function in the set of code codes has become smaller (for example, has been minimized), so that the storage space in the program memory 124 is reserved for the corresponding code in the set of codes. The code for other functions.

According to certain embodiments, the operation of step d can be varied. For example, operating the data in the at least one shared variable may further comprise: applying at least one operator to the at least one shared variable (eg, a shared variable VARIABLE, or a shared variable {variable1, variable2, variable3, ...} The information in the ) to generate the latest information in the at least one shared variable.

For example, the symbols {OP_A, OP_B, OP_C, OP_D, ...} may represent operators, examples of which may include (but are not limited to): read, write, various operations (such as addition, subtraction, multiplication, division, modulo (mod) ) Operations...etc.) and various operations involving reading/writing. The above conventional methods may operate various array variables such as array variables {variable1[x], variable2[x], variable3[x], ...}, as shown in the following virtual code: (in C language as an example) for(x= 0; x<N; x++) // N is Number of Port { OP_A variable1[x]; // Operate array variable variable1[x] OP_B variable2[x]; // Operate array variable variable2[x] OP_C variable1[x ]; // Operate array variable variable1[x] OP_D variable3[x]; // Operate array variable variable3[x] }

In contrast, the method of the present invention can operate the shared variable {variable1, variable2, variable3, ...} (which is a non-array variable) through the variable access service, as shown in the following virtual code: (in C language Example) for(X=0; X<N; X++) // N can represent the number of { { memcpy(shared_memory, port_memory[X], memory_size); // copy the data storage area corresponding to index X to shared memory Storage area OP_A variable1; // Operation shared variable storage area SHM shared variable variable1 OP_B variable2; // Operation shared memory storage area SHM shared variable variable2 OP_C variable1; // Operation shared memory storage area SHM Shared variable variable1 OP_D variable3; // Operation shared variable in shared memory storage area SHM variable3 memcpy(port_memory[X], shared_memory, count); // Copy shared memory storage area to data storage area corresponding to index X} The pointers shared_memory and port_memory[X] can point to the shared memory storage area SHM and the corresponding index X, respectively. The material storage area PM(X), the value memory_size may represent the size of the entire area of the data storage area PM(X) (for example, the size of the data storage area PM(X) is equal to the size of the shared memory storage area SHM), and the above The loop in the virtual code can be used as another example of the variable access service loop. For example, the predetermined program module can be a function, and the function can include the loop, but the invention is not limited thereto. Table 1  <TABLE border="1" borderColor="#000000" width="85%"><TBODY><tr><td> Memory Requirements</td><td> Traditional Method</td><td> The present invention Method</td></tr><tr><td> Data Memory Requirements</td><td> Q * M * N </td><td> Q * M * (N + 1) < /td></tr><tr><td> Requirements for program memory</td><td> M * K * (T + R) </td><td> 2 * S + M * K * R </td></tr></TBODY></TABLE>

Table 1 is a comparison table between the conventional method and the method of the present invention. Regarding the demand for data memory, Q is the average size of the variable, M is the number of variables, and N is the number of ,, where (Q * M) can be called the total byte count; for example: at least Each of the variables may occupy one byte, and/or each of the at least one variable may occupy a plurality of bytes. Since the conventional method uses array variables (for example, array variables {variable1[x], variable2[x], variable3[x], ...}), the storage space of the required data memory is the sum of the storage spaces of all the array variables, that is, (Q * M * N) Bytes. In addition, since the method of the present invention uses general variables, the storage space of the required data memory is the sum of the storage spaces of all the general variables (ie, the total number of bytes (Q * M)) and multiplied by (N + 1). That is, (Q * M * (N + 1)) bytes, where 1 means an additional general variable (which is stored in the shared memory storage area SHM). For example, the size of each of the data storage area PM(X) and the shared memory storage area SHM may be equal to the total number of bytes (Q*M).

Regarding the requirements of the program memory, M is the number of variables, K is the average number of times the variables are read/written, and T is the amount of machine code that needs to be additionally processed by the array when the microprocessor accesses ("8051" type micro For example, when using a compiler and an optimization level, when reading array variables, it is 10 bytes more than when reading general variables. The array variable is 12 bits more than when the general variable is written, but the present invention is not limited thereto, and R is the machine code amount of the microprocessor operation (for example, mathematical operation, logical operation, access, etc.) variable. S is the machine code of the function memcpy( ). The method of the present invention saves the machine code amount corresponding to (M * K * T), although it is more than the machine code amount corresponding to (2 * S), which is usually much larger than the corresponding (2 * S). The amount of machine code. Therefore, the method of the present invention can greatly reduce the machine code size of at least one program module (such as one or more program modules), and can give the electronic device 100 a lot of functions under the condition that the hardware resources are rather limited. The diversity of functions of the electronic device 100.

According to some embodiments, the program memory 124 such as the instruction memory may be a volatile memory (for example, a static random access memory (SRAM), a dynamic random access memory (Dynamic Random Access Memory). Memory; can be abbreviated as DRAM), or non-volatile memory (such as Mask Read-Only Memory (Mask ROM), Flash Memory; Referred to as Flash), Electrically-Erasable Programmable Read-Only Memory (abbreviated as EEPROM), etc.). According to some embodiments, the data memory 122 may be a volatile memory (eg, SRAM, DRAM, etc.), or a non-volatile memory (eg, Flash, EEPROM, etc.). According to some embodiments, the program memory 124 and the data memory 122 may share the same physical memory or use respective physical memory. For example, if you want to share, you can't use Mask ROM. According to some embodiments, the machine code may be fabricated only in the Mask ROM within the integrated circuit (IC), or may be only burned in the Flash or EEPROM, or may only be loaded into the random access memory. However, the invention is not limited thereto. For example, the machine code can be created in a Mask ROM in an integrated circuit, burned in Flash or EEPROM, and/or loaded into random access memory. According to some embodiments, the benefit of reducing the amount of machine code may include adding a program corresponding to more functions in the original storage space of the program memory 124 to increase the added value of the electronic device 100, and/or reducing The size of the program memory 124 is reduced to reduce cost. Depending on certain embodiments, different compilers or different levels of code optimization related settings may affect the machine code size.

In addition, in addition to the use of array variables, the conventional method may also use indirect access such as pointer variables, struct variables, union variables, and mixing of the above variables (additional processing of arrays/indicators is required). The index (array/pointer index) or structure/joint member (struct/union member) variable of the value. In contrast, the present invention can reduce the amount of machine code through the variable access service. For example, in some embodiments, a generic variable can generally refer to a variable that does not require additional processing such as array/index indexing or structure/joining members. According to some embodiments, in the data storage area PM(X) corresponding to the index X, the size of the different variables may be different, for example, the variable(s) may occupy 1 byte, and some (some) variables Can occupy 2 bytes, some (some) variables can occupy 4 bytes, and / or some (some) variables can account for more than 4 bytes.

In addition to the variable access service loop to implement the above-mentioned partial program, the method of the present invention can also implement the partial program in a non-loop manner. For example, the method of the present invention can operate the shared variable {variable1, variable2, variable3, ...} through the variable access service, as shown in the following virtual code: (in the C language as an example) void func(void) { OP_A variable1 ; // Operation shared variable storage area SHM shared variable variable1 OP_B variable2; // Operation shared memory storage area SHM shared variable variable2 OP_C variable1; // Operation shared memory storage area SHM shared variable variable1 OP_D Variable3; // Operation shared variable storage area SHM shared variable variable3 } // 埠0 memcpy(shared_memory, port_memory[0], memory_size); // copy the data storage area corresponding to index X (X = 0) to Shared memory storage area func(); memcpy(port_memory[0], shared_memory, memory_size); // Copy shared memory storage area to data storage area corresponding to index X (X = 0) // 埠1 memcpy(shared_memory , port_memory[1], memory_size); // copy the data storage area corresponding to the index X (X = 1) to the shared memory storage area func(); memcpy(port_memory[1 ], shared_memory, memory_size); // Copy the shared memory storage area to the data storage area corresponding to the index X (X = 1) //....... // 埠(N - 1) memcpy(shared_memory, port_memory[N- 1], memory_size); // Copy the data storage area corresponding to the index X (X = N - 1) to the shared memory storage area func(); memcpy(port_memory[N-1], shared_memory, memory_size); Copy the shared memory storage area to the data storage area corresponding to the index X (X = N - 1) where func( ) can represent the function. The operation of the variable access service loop described above has been broken up into N sets of instructions of the reference function func( ), so that the microprocessor 110 performs the variable access service loop as in the index X, but the invention is not limited thereto. this. The N sets of instructions (of the reference function func( )) can simulate the variable access service loop, but the invention is not limited thereto.
